Beethoven Analysis – Piano Sonata in Cm (Op. 10)

AUTHOR’S NOTE: I will continue analyzing Beethoven sonatas in blogs but I will no longer make YouTube videos on the subject as it takes way too much time. I have also struggled with some time to describe melodic line and harmony changes without being tedious, sounding like I’m merely describing every little thing in the music, and making YouTube videos does not help. I should hopefully do better. – I should still learn to condense this a bit. Sonata form movements are the hardest. It should only have 4 paragraphs.

The Cm sonata (Op. 10) is Beethoven’s first published piano sonata to have only three movements instead of four. Beethoven wrote the first four sonatas to sound like symphonies through many different means; he wrote them in four movements, wrote each movement to be large to allow subjects much space to develop, and often writes for orchestral parts such as clarinet parts in the Fm sonata (Op. 1) and horn parts in the Eb sonata (Op. 7).

Now Beethoven tries something different and writes a more typical sonata; with only three movements and with no obvious orchestral parts. Still, Beethoven develops his subjects and follows his ideas in a clear, forceful, concise way, in fact even more so in this sonata. It is useful to see the striking differences between this Cm sonata and the Fm sonata (Op. 2) Beethoven wrote a while back as both are dark and impassioned music but approached in very different ways.

The way Beethoven ends this sonata is also important; a fizzling out to a quiet finish rather than slamming thick chords at the end. Indeed Beethoven ends many future sonatas in this way as an alternate way to finishing a piece of music and fulfilling the journey back to the home key.

Allegro molto e con brio

The first movement is in sonata form and is based on the Mannheim rocket; an intense phrase where notes rise in a broken chord to a high register. The main subject in Cm is short but complex, broken into three parts. In the first part Beethoven forces two sharply contrasting colors together; a thundering Mannheim rocket played in dotted notes to make it even more intense followed by a soft sighing motif. In the second part Beethoven builds off a descending scale, starting at a high G (the dominant note), and repeats it, each new phrase more intense, until he hangs at a low G (again the dominant note). In the third part, Beethoven suddenly breaks away into new material again; right hand arpeggios resolving in Cm. Beethoven consistently plays Cm and Bd (diminished) chords the entire time, using Bd as a darker counterpart to G7. He uses only two chords for most of the main subject but he does much with them.

The transition is simply the Mannheim rocket again, using G (again) as the high note. Beethoven simply uses Cm and G the entire time and simply decides to break it off after he resolves in Cm. The main subject and transition here are very different from their counterparts in the Fm sonata (Op. 2). The Fm sonata main subject is far simpler as it slowly moves from piano to sforzando using a simple Mannheim rocket the entire time. The Fm sonata transition, by contrast, is complex as Beethoven makes a big deal modulating to Ab, using Dba (augmented) and Bbm to spice things up. But in this Cm sonata, it is quick and simple. Beethoven is fine jumping from Cm right to Eb (the mediant).

The subordinate subject is based on the submediant; the first phrase starts in Eb7, the second in C7, the third in Ab7. A simple descending base makes up the backbone while the soprano and alto parts fill the harmony in. From now on Beethoven stays in Eb, which is pretty typical for classical sonata form. The second subordinate subject is a rising arpeggio with an Alberti base underneath, harmonies simple Eb-Bb7. He quickly gets more interesting with a chromatic melody, using Ad and Aa harmonies. He thunders with the Mannheim rocket again for a while so he can lead us to the closing subject, but he uses Ebd and Cd7 instead of Bb. The closing subject itself is built on the small sighing motif we saw way back in the main subject to slowly fall to a low Eb, while Beethoven uses some Cm7 and Gm7. The purpose is to darken the Eb closing theme a bit and connect it to the main theme in Cm, to show how close we are to dark and minor keys.

Beethoven builds the development with two cores, both based on the less striking melodies in the exposition. He elevates those melodies by playing them in octaves in a very singing manner. But first he needs to make a bridge to lead you to the first core; and he does this with the Mannheim rocket subject in C (submediant leap from Eb), and he uses it like he did with the transition by cutting it off after he resolves. The first core in Fm is based off the filler melody of the first subordinate subject underscored by an Alberti base. The second core in Bbm is based off the second subordinate subject while the base is taken from the closing subject. The retransition is based off the sighing motif but he strings many motifs together to make a long melodic descent all the way from a high G (dominant) to middle C (tonic). Meanwhile, he keeps the base at G to emphasize a V-I return to the main subject. But do notice how many different harmonies Beethoven plays throughout; it’s anything but a boring V-I for 11 measures.

The main subject is just as before and Beethoven skips a transition altogether, making the journey even more streamlined. The subordinate subject comes right after, now in Db7 (IIb7 of Cm), and he breaks his descent by submediant theme to quickly move to Cm. However, do note how he frequently plays C also, the mutation of Cm to make the harmonies more interesting. But the quick resolution to Cm is a ruse. The second subordinate subject is in F instead (mediant of Db) then quickly goes to Fm (the subdominant of Cm). This is important as the subdominant is usually emphasized in a recapitulation but Beethoven delays for a while to keep the listener guessing. The closing subject neatly wraps it all up in Cm.

Adagio molto

The second slow movement is in sonata form without development but with a coda with a variation of the main subject. The main subject is in Ab and is played twice; the first in its “base” form and the second as a variation where the base becomes arpeggios and repeating 16th notes. The subject is based on a rising and falling third, the melody rises to a climax in Db (the subdominant) before making a long fall back to Ab. The transition is a striking contrast to the lyrical subject; a loud drop by two octaves. The harmonies sometimes blur together in the little sighing motifs and, while F7 is a striking submediant leap from Ab, the harmonies are the usual ones around Cm.

The subordinate subject in Eb is made of two different parts. The first part; we have a rising 3rd motif similar to the main subject, and it also peaks at a subdominant note (Ab in this case). The virtuoso 64th note arpeggios in Bb9 is a development of the rising 3rd. The second part; a long rising scale from G to Eb on dotted notes. This would be boring in itself but Beethoven uses Eba, Dd7, and Ad7 to make chromatic use of it. The variation that follows peaks in the harmony of Cb7, the tension highest in a distant key of Eb. The retransition is based on the subordinate subject and is in Eb, preparing to return to Ab.

The main subject has little change in it except some variation in the base, first dotted notes and later arpeggio triplets. The transition has an extra phrase; sighing motifs clumped together to make a chromatic descent to Db. Beethoven uses many distant keys such as Fb, Gbm, and Fhd7 (half diminished); a striking alternate way to going to the dominant. The usual method is F-Bb-Eb or Dm-Bb-Eb, but Beethoven plays odd F chords before going to Bb-Eb.

The subordinate subject and retransition are almost verbatim similar as before except now in Ab. The coda is a variation of the main subject, now in cantabile as we have a viola part in the middle made of syncopated notes. The coda has no dramatic peaks but simply slowly falls down the Ab scale: from Eb5 to Ab4, from Ab4 to Ab3.


The finale is in sonata form but is very brief, much like rondos of classical sonatas, a breezy finish. Still, it has some weight. The main subject is based on a rising chord, this case Cm, but the melody dramatically peaks in dissonant F while the harmony is F#d7. The second time around Beethoven climbs up the G scale and peaks at F again while the harmony is in Fm. Then the rhythm intensifies to 16th notes so Beethoven can rush down to G (dominant) with flair. There is no transition. A jump from G to Eb happens instead. Notice how the melodic line of this main theme climaxes on a subdominant note, not too unlike the main theme from the last movement, while also highlighting G like in the first movement. The harmonies matter too; Beethoven sometimes mutates Cm to C, while he uses the F#d and Bd chords to lead to G and Cm.

The subordinate subject is based on a rising and falling 3rd with a distant last note; it reaches a sudden climax in Ab (subdominant). At first Beethoven falls to Bb into what seems a quiet finish but suddenly rises to Eb at the last moment; a creative way to avoid a typical resolution. The closing theme uses the turn motif of the main subject over different registers, and it peaks at Ab (again subdominant) before resolving to Eb. Beethoven then resorts to more distant harmonies; Ed and Bd, diminished versions of the tonic and dominant, and frequently uses Fm and Cm too. He does all this to make the ear less certain it is in Eb, making Cm stronger. He also drops a sudden Cb7; instead of going from Bb to Eb to goes from Bb to its Neapolitan (IIb7/V).

We only have a small development of the main subject motif; though in Eb it uses Bd, Dd, and Bb, all related by a 3rd. Beethoven also briefly uses C7 to again disrupt the expected Cm and he develops the melodic line by having it rise to a very high F (subdominant of Cm). The main subject makes little change while the subordinate subject is in C (mutation of Cm), except with a chord progression from Dm-D7-G. The closing theme is different, starting with the main subject motif rather than a tremolo. The next part has the same chord structure as before except tailored around Cm; this includes C#d leading G and the sudden drop now in Ab7. The closing theme halts, holds the tension on suspended Ab7, withholding the ending.

We enter a brief coda based on the subordinate subject in Db, the music suspended in a slow calando. It’s mostly V7-I except for a brief Ebm-Eb-Ab (chromatic base) and how the colando suspends in Ad7. Then, an abrupt eruption as the music resumes its normal tempo, but rather than race to the finish it fizzles out, slowly moving from Ab to C. Beethoven does this by pretending the C is just Cm and playing the usual nexus of neighboring chords. The melodic line, back in the main subject motif, starts at a high Eh note but falls down the C chord to lowest C on Beethoven’s pianoforte. The lowest range of the pianoforte back then was F1.

Beethoven Analysis – Piano Sonata in Fm (Op. 2)

Beethoven’s first published piano sonata is far longer and more complex than his Kurfursten sonatas, and we see the mature Beethoven for the first time. His basic musical tastes, harmonies, and means of developing material stay firmly in place despite him transforming through three different styles. We also see Haydn’s influence in using a few notes (like the Mannheim rocket) as a base to build the entire movement. Beethoven composed this sonata when he was only 25.

A complete formal and harmonic analysis of the piano sonata is in the video above, a general outline of the form is below.

Form of Fm (Op. 2)

00:00 – The 1st movement uses the Mannheim rocket for its main subject and its inversion for the first subordinate subject. He uses the melody to create a hard dissonance (m2nd) against the harmony of the base. He blurs harmonies a lot with his “triplets” in the second subordinate subject.

5:38 – The 2nd movement is made from recycled material from an unpublished piano trio, but now the material is more complex and is developed more. It features complex melodies with a strong emphasis on rising and falling and a sighing motif. Beethoven is also fond of mixing a chord in the base with a note in the treble that implies the chords’ subdominant. Like in the 1st movement, he cadences with an 11 chord.

10:28 – The 3rd movement has has a murky feeling. The minuet is in Fm, yes, but it doesn’t sound like such a clear, tragic minor piece, because Beethoven uses Bbm (ii) a lot along with Fm. His orchestration as it were is frequently is in 4 parts, suggesting a string quartet. The trio is more straightforward, using a chromatic C-Bh-Bb descent in its latter parts.

13:13 – The 4th movement is volcanic, with less restraint than the other movements, as if Beethoven saving the pent up energy for the last movement. It’s main subject makes great use of 1st-7th-1st notes, a simple cadence, with V9 and viihalfdim chords. The transition is very dense, with many different harmonies squeezed into one measure, like Beethoven is trying his hardest not to play I-V. The subordinate subject is in a minor key (Cm, Fm) but frequently stays in the mediant (III) (Eb, Ab). The long downward scales give a dramatic, tragic feeling to the music, a falling down to ruin.

Beethoven Analysis – Piano Sonata in Eb (WOo47)



We first see Beethoven writing piano sonatas in 1783, not the wild man we turned into a titan genius through myth but a mere boy of twelve. By this time Beethoven’s father Johan could no longer teach his son through his brutal methods so he turned his son over to more able tutors such as Christian Neefe, who introduced the young Beethoven to Johan Sebastian Bach’s Well-Tempered Clavier. The boy learned quickly, practicing on the piano long past midnight for many nights to refine his skills, soon mastering J.S. Bach’s works.

Beethoven occupied himself with other tasks and hobbies. He played the organ in his church and the viola in the court orchestras of the prince electors ruling Bonn at the time. – The nation of Germany did not yet exist; the land was part of the Holy Roman Empire, broken into many small territories each ruled by a different prince. – In his spare time, Beethoven frequented the local university lectures, salons, and other forums, and quickly became enchanted by the principles of the Enlightenment, ideals he held until his final days.

The young Beethoven composed his first three piano sonatas in this climate, dedicating them to his Prince Elector Maximillian Frederick as per custom. The pianist Ronald Brautigam describes, in his booklet that comes with his recordings of Beethoven’s piano sonatas, that Beethoven drew heavily on Carl Phillip Bach’s “sensitive style” keyboard works and Haydn’s “storm and stress” piano sonatas. He then mentions how Beethoven was lucky his father was too drunk to discipline his son to compose in a so-called proper style; had Mozart tried to write such music his father would have stopped him.

I am listening to C.P.E Bach’s keyboard works as I write this very essay and I do hear some of the same muses who stirred Beethoven when he was only a teenager and would inspire him for the rest of his life. The music is indeed in a “sensitive style”, with touching melodies one moment and stormy, abrupt chords in another, elements Beethoven puts in his own sonatas. I hear adolescent melancholy, youthful play, ventures in playing dark and difficult music, and some sight into the abstract realms music takes you when you really listen to it.

Let us now study the first of these earliest sonatas. I created a road map, posted just below this paragraph, and a YouTube video with the entire sonata in annotations, link at

Scan Forms i


The first movement, unlike Beethoven’s later sonatas, does not have any clear first subject, second subject, and so forth. It is like Mozart’s earlier sonatas and Classical ideals in general; you hear one gracious melodic line, then another, a new idea develops, all in balance and harmony. You can really think of movement one’s sonata form as a few melodies in Eb, then a few melodies in Bb, and so on.

Beethoven thinks along these lines of balance and harmony, his ideas mostly abstract, not trying to state any definite idea. He does explore a simple contrast between a high delicate woodwind range, a warm middle string range, and low stormy range. He does put more thought in his later “Kurfursten” sonatas on what he wants to say and how to say it; in the Fm sonata he explores loftier thoughts, but he is not used to writing in sonata form at the moment. Give the kid a break. He should do better things anyway, like try to get rid of his pimples, go to Hot Topic, and flirt with girls.

Beethoven’s “main subject” is made of a few melodies with little relation, but they do connect in the same way a few sentences create a paragraph; the paragraph being the “first subject”. The boy does put some color and contrast between sentences; sentence one has a rising then falling arc and implies a string ensemble (bars 1-4), another sentence leaps then falls in a woodwind’s register (bars 11-14).

When he modulates he plays many sixteenth notes to amp up the tension. Beethoven is technically in Bb already but he wants to establish a Bb harmony by modulating, so he does so as if he was in Eb in two sentences. In his first sentence he starts his first phrase in Bb, the second phrase in C (bars 15-18). He changes the harmony by moving it up a whole step, a technique Beethoven is fond of. The whole point of his exercise is to move to F, the V chord (or dominant) of Bb. By using the F harmony, Beethoven “overshoots” so he can play a V-I cadence of F-Bb.

The “subordinate subject” (bars 25-30) is very short and also counts as a closing statement, but what a striking and playful tune it is! Beethoven plays it twice, once as a flute, another as a violin. He brings back a similar contrast as before in his “first subject” but the order is reversed (woodwinds first, strings second). Beethoven does develop a few simple ideas; a contrast between high and low keys, and he develops it further.

We can break down the development into two “cores” where Beethoven explores an idea in the exposition. The first “core” . (bars 30-40). imitates the second idea but in Cm, among the highest keys. Nothing too new here. The second “core“ (bars 48-55)  is made of arpeggios in minor chords, mostly Cm, the register low, dark, stormy. He retransitions to the “main subject” easily by playing Bb then Eb.

I can only comment little on the recapitulation since everything is the same as before, just a 5th lower, in Eb. The only difference is the “main theme” is truncated, so we only hear one sentence. For a while I wondered by Beethoven played a sentence in Bb so soon (bars 11-14) but I may have a clue now. Beethoven may have seen how the line in the recap is in Eb exactly repeats the line in the expo, so he may have changed the latter to Bb to avoid repeating himself and create a bigger feeling of returning home as the movement closes.


Beethoven shows his true talent and craft in this movement. Like in many sonatas, including the Fm sonata, the middle movement is the heart of the sonata, the highest seat of thought and feeling and a fulcrum between the two fast movements. Beethoven uses this form in many later sonatas throughout his career but he takes it to a much higher level. A good slow movement can change the nature of the entire sonata, such a crucible seems to transform the music as you go from the first movement to the last movement. As a composer myself, I find slow movements hardest to write but when I do it somehow helps me write later fast movements far better.

In the second movement we can really see Beethoven express the sensitive style he picked up from C.P.E. Bach as he sings his lonesome and tender song. The constant mood is of adolescent melancholy; you truly understand how sad and lonely this boy was, with no intimate friends, with only a few sensitive adult women to comfort and protect him. Already we see the young Beethoven improving as a composer in learning what emotions to express and what techniques he needs to do so.

Beethoven sets this mood by cleverly using chromatic notes in the treble and base and in the way he uses his sentences; he makes them “two-bodied” where the first phrase or clause, if you can call it that, is simpler and the second one is more complicated and intense. You tend to hear this in the second part (of B part) of the exposition and recapitulation. However, his base is somewhat staid, as he plays Alberti base for almost the entire movement. He lets the melody do most of the work and, like in a lot of early classical music, the base is used for harmonic filler.

In the main subject and very short transition (bars 1-13), Beethoven makes both Bb and Eb natural. This adds color, yes, but also suggests the key of C, which is the V chord of F, the dominant. He plays a chromatic rising base as he transitions, up from Bb, to B, to C. This way he plays an inverted F chord, making the cadence imperfect, keeping suspense kind of like how a novelist refuses to resolve the plot of a story just yet. The harmonies he implies throughout are Bb, F, C, F (IV-V-V/V-V), again he “overshoots” by playing a C-F cadence, which is V-I relative to the key of F.

Beethoven writes two subordinates subjects in F. The first subject (bars 14-19), is in the tenor and base registers. Beethoven suggests a viola and cello, the warm tones contrast high notes in the rest of the piece. It is a shame Beethoven doesn’t use more contrast. He again plays a chromatic rising base, this time suggesting Bb-F (IV-I) harmonies, and again keeps us in suspense with an imperfect cadence.

The second subject (bars 19-25) is more straightforward. The harmony is “offbeat here”, starting as V-I not I-V, and Beethoven plays a string of 32nd notes in fortissimo afterward to intensify the emotion. He also plays an F# note, implying Gm to make the harmony more ambiguous. Beethoven is very fond of the F# and Bh chromatic notes in the second and third movement of this sonata. And finally, he plays a perfect cadence at the end, resolving the tension he set up earlier and leading us to a poignant closing statement (bars 26-31).

The development section (bars 31-37) is very short but Beethoven makes good use of it by playing many chromatic notes; these include F#, G#, Eb, and C#. While Beethoven technically plays F-C7 (I-V) the whole time the chromatic notes imply other harmonies like Am, Cm, and Dm. In the very brief retransition he plays the Bb note at the end to imply a subdominant harmony (relative to the key of F) to return to the home key of Bb.

The recapitulation, like in the last movement, repeats the exposition almost verbatim, most of the material is transposed a 4th higher. The main subject (bars 38-42) is shortened so much it merges with the transition to make one sentence. The second subordinate subject (bars 49-56) has an extra bar but it is important. Beethoven uses it to play an Ab note; at the moment it suggests a Bb7 chord but in the entire subject it creates a strong subdominant feel. Most composers at the time dwelled in the IV chord in their recapitulations to anchor your sense of hearing back to the home key and usually to play a IV-V-I harmony. Beethoven does something similar here.


Beethoven changes form in this movement; now he opts for a rondo form not the usual sonata form, but it does sound a lot like a sonata. Its three main stanzas of A,B,C each resemble an exposition, development, and recapitulation, and each stanza is made of four lines of a,b,c,d. Like the first movement, this last movement is made of a string of different melodies that have little relation to each other but the emotions expressed are more intense. The major lines are more zesty and playful, the minor ones more brooding, the cadenzas otherworldly.

In stanza A, line a (bars 1-8) is a theme in Eb in the standard I-V-I harmony. Line b (bars 9-16) acts like a transition of sorts; Beethoven plays a arpeggios throughout to fill out harmonies, he toys with a chromatic rising base a bit to create Ebaug harmony, and later modulates by playing Bb-Cm7-F-Bb. Line c, the “subordinate subject” (bars 17-23), Beethoven plays arpeggios again, just with the hands reversed, plays Bb and Eb to create a I-IV-I feeling, as if he didn’t modulate to Bb at all. Beethoven ends the line by playing Edim7 then holding out on F a bit. This is a diminished cadence where the composer plays viidim7-I rather than the usual V-I (relative to F in this case). It adds some spice to the music and lets the composer travel to a distant key easily without having to worry about a V-I cadence. It becomes clear to us at this point this piece focuses more on harmonies than having distinct melodies, a contrast to the first two movements, especially the second movement.

His closing statement is in two sentences (bars 18-36). Beethoven must get back all the way from F (which is a whole step above Eb, notice how this parallels the first movement) to Eb. He does this by going down the harmonies by 4ths, from F to Bb to Eb. Once there, he goes briefly to Cm before going to Bb (playing I-V-I) where he suspends us in a Bb chord. We are now in the end of stanza A, the suspending chord acts as a cadenza, which many pianists fail to improvise as they lack invention.

Stanza B begins. Line a (bars 37-44) is our familiar first tune. Now in line b (bars 38-55), we enter the first “core” of a “development” section. Here Beethoven explores the arpeggios from before but this time he cycles through a bunch of flat harmonies close to Eb; these are Ab, Fm, Bb, Gm, Cm, Bb7, and F7. The second “core” in line c (bars 56-62), he plays a Ebdim7-F cadence so he can hold on to F a bit. Then in line c, the “retransition”, (bars 63-71) he hangs around Ebmin (the minor version of the home key) before arriving to a second cadenza in Bb.

Stanza C mimics a recapitulation but Beethoven is more inventive here than in the last two movements. Before he played the exact same material just a 4th below in harmony. Now he does a few new things. We hear the first tune again (bars 72-79) as a “main subject”, barely any different than before. In line b, the “transition” (bars 80-87), he moves to Cm. He returns to using diminished cadences, this time twice; first with Bdim7-Cm, then with F#dim7-G. In line c, the “subordinate subject” (bars 88-99), is in Eb with the standard V-I, spiced up a bit with Ab (the subdominant) and another diminished cadence from F#dim7-Gm. Next Beethoven hangs around Cm, playing V-I with some Fm in it. This Cm sentence thus mirrors the Eb sentence before.

We enter the final cadenza, the notes held out in a single voice on the C note. Then we enter line d, the “closing section” (lines 100-109), where the main tune repeats again with a small extra flourish at the end to finish the movement. The main Eb theme changes very little throughout the entire movement, which shows how the young Beethoven is still pretty new to sonata form. The mature Beethoven would never repeat himself like that, a good counterexample being his “Rage Over a Lost Penny” rondo. He transforms the theme in so many ways; he changes its register, plays it in a remote key, diminishes it, embellishes it, shortens it, develops bits of it elsewhere in the piece, makes at least two variations out of it, uses it build a coda, and so on, all in five and a half minutes. However, the young Beethoven’s genius is emerging, even now he is getting the knack of writing complex and passionate music.
