Lesson 2 · AMEB List A · Classical
His only C minor sonata — a stormy drama that refuses a happy ending, and the one Haydn himself called "the longest and most difficult".
Joseph Haydn spent most of his working life as the music director for one very rich family — the Esterházy princes — living in a grand palace far from any big city. Being cut off from the world was, he said, his secret weapon.
1732 born in Rohrau (a village in Austria) → choirboy in Vienna → years of odd jobs → 1761 joins the Esterházy court (full Kapellmeister 1766) → two famous trips to London (1791–92, 1794–95) → dies 1809.
① Called the "father of the symphony" and of the string quartet.
② A close friend of Mozart; Beethoven studied with him.
③ His works are numbered Hob. (Hoboken catalogue, grouped by type — XVI = keyboard sonatas).
About his lonely years at the Esterházy palace: "There was no one near me to confuse or torment me, and so I was forced to become original." Being alone made him invent.
This sonata has a lot of labels. Get them all right and you look very organised.
Hob. XVI:20 (Hoboken) = Landon 33 (chronological) = Op. 30 No. 6 (the old print). Always quote the Hoboken number — "Sonata No. 20" is ambiguous because under Landon it means a different piece.
Dated 1771 on the autograph, published 1780 (Artaria, Vienna — announced in the Wiener Zeitung, 12 April). Nine years. The usual explanation is his Esterházy contract — but see the box below, because that answer does not survive contact with the evidence.
Last of six sonatas dedicated to Katharina (1755–1825) and Marianna (1759–1782) von Auenbrugger. Haydn to Artaria, 31 January 1780: "Übersende die 6te Clavier Sonate, weil dieselbe die längste und schwerste ist" — "I am sending the 6th keyboard sonata, because it is the longest and most difficult." Note he wrote Clavier, not pianoforte.
It is a good description and a bad citation. The phrase is Richard Wigmore's, from his Haydn guide and a 2012 liner note. It appears in no musicological monograph. So say "Richard Wigmore calls it Haydn's Appassionata", never "it's known as". And don't confuse it with Symphony No. 49, "La Passione" — that one is a genuine, long-established Haydn nickname from these same years.
The dedication was the publisher's act. Haydn wrote on 20 March 1780: "I only regret one thing, that I cannot have the honour of dedicating these Sonatas to the Demoiselles von Auenbrugger myself." A small correction that shows you have read the letters, not just the liner notes.
The AMusA rule is blunt: "One work must be chosen from List A. At least three works must be chosen from any of Lists B, C, or D." List A is not "Classical" — it is the large multi-movement repertoire: sonatas, suites and variation sets, from C. P. E. Bach and a Bach French Suite through twelve Beethoven sonatas, Clementi, Dussek, Field, nine Haydn sonatas, ten Mozart sonatas and three Schubert sonatas. So this sonata is doing double duty in your programme: it is the single compulsory pillar, and — at fifteen to twenty minutes — it is also most of your 25-minute timing floor. Both of those facts should change how you rehearse it. Full list breakdown →
You will read everywhere that the nine-year gap was contractual: clause 4 of Haydn's 1761 Esterházy contract bound his music to the family, the 1779 contract dropped the clause, and publication followed. Both halves of that are true. The causal link between them is not.
Two problems. First, clause 4 forbade composing for others "without the knowledge and permission of His Highness" — a permission clause, not an absolute ban. Second, and fatally: Haydn had already authorised a public print of six other sonatas in 1774 (Kurzböck, Hob. XVI:21–26), and another set circulated in 1776 — all while this sonata sat unpublished. Landon's verdict on the clause is blunt: it "had long been a dead letter anyway."
So why did this one wait? A. Peter Brown's suggestion is far more interesting: that it was held back because the first movement was unfinished — and Henle indeed calls the 1771 layer an Entwurf, a draft. Remember what is missing from the autograph. The likeliest answer is not a lawyer's, it is a composer's: the piece wasn't done yet.
The 1780 title page says "per il Clavicembalo o Forte Piano" — "for harpsichord or fortepiano". That's a snapshot of history: the piano was so new that publishers had to sell the same music to owners of both instruments.
Haydn's own manuscript of this sonata survives, it is free to look at on your phone, and it contains a surprise.
The autograph lives in the Bibliothèque nationale de France in Paris (MS-133) and is digitised free on Gallica. It is not a complete manuscript: it holds the first movement bars 1–37 (plus sketches for what follows and for the final bars), and the finale bars 1–130. And in between — nothing. The A♭ major Andante is not in the autograph at all.
Nobody is certain why. Henle says simply that whether it had been sketched by then "is unclear". One scholar, Ulrich Leisinger, goes further and argues the slow movement was composed new for the 1780 publication. If he is right, the emotional centre of your sonata is 1780 music sitting inside an 1771 frame — and the nine-year gap stops being an accident of paperwork and starts being a compositional history.
The heading reads "Sonata p[er] il Clavi Cembalo | In Nomine Domini | di me Giuseppe Haydn mpria". Haydn began nearly every manuscript "In the name of the Lord" and ended it "Laus Deo" — praise be to God. It is right there on the first page of your sonata.
The year is written as three digits, and A. Peter Brown warns the last numeral is ambiguous — it may read 771 or 777 — and "should not be accepted without question". So even "1771" has a small asterisk on it.
Haydn's heading says Clavicembalo — harpsichord. Yet the same pages carry f and p marks a harpsichord cannot execute. Whatever he meant, he wasn't being tidy about it.
Because the autograph is partial, a modern Urtext follows it where it exists and the 1780 first edition everywhere else — so your score is a seam of two documents. That is also why the first movement's tempo marking differs: see below.
The autograph reads "Moderato". The 1780 Artaria print reads "Allegro moderato", and so do Henle, Universal and Peters. Some free scores online print the autograph's reading. Brown treats exactly this change as evidence that Haydn revised the movement before publishing it — a slightly faster, more urgent basic tempo, chosen nine years later.
So don't just look up "the" tempo marking. Look at yours, and know which document it came from. "My edition prints Allegro moderato, which is the 1780 first edition; the 1771 autograph says only Moderato, and the difference is one of the things that shows he went back to the piece" is a Distinction-level sentence.
Around 1768–72, Haydn's music got darker, bigger and more daring. This phase has a dramatic German name: Sturm und Drang — "storm and stress".
Minor keys, sudden loud–soft contrasts, dramatic silences, wide leaps, unexpected key changes — music that surprises and frightens instead of being politely neat. Your sonata is full of all of these.
Symphony No. 44 "Trauer" (Mourning), No. 45 "Farewell", No. 49 "La Passione", and the Op. 20 "Sun" string quartets — all around 1768–72.
The son of J. S. Bach, C. P. E. Bach, wrote in an emotional "sensitive style" (empfindsamer Stil) that Haydn loved. The abrupt gestures and speech-like "recitative" moments in this sonata point straight to him.
The label is borrowed, and the borrowing is anachronistic. Klinger wrote the play in 1776 and it was premiered in 1777 — after this music. (It was originally called Wirrwarr, "Confusion"; a friend talked him into the better title, and Klinger later grumbled that it was forced on him.) Nobody applied it to Haydn until Théodore de Wyzewa in 1909, and it was H. C. Robbins Landon who made it standard.
The objection is live scholarship, and you can quote it. James Webster in New Grove: the term "properly pertains to a literary movement of the middle and late 1770s rather than a musical one of about 1768–72, and early proponents of this interpretation assumed implausibly and without evidence…" Clive McClelland calls the label "demonstrably unsatisfactory" and proposes tempesta instead.
⚠️ But don't overclaim the fix. It is sometimes said that scholars therefore "prefer empfindsamer Stil for the keyboard works." That is not a documented consensus — the C. P. E. Bach influence is thoroughly established, but that is a different statement from replacing the period label. The strong answer is: "I use the term because everyone does, but I know it's a 20th-century import from a play written after the music, and Webster in Grove thinks it does more harm than good." Having a view beats having a label.
Examiners love this one, and the answer is not a single word. The scholars genuinely disagree — and explaining the disagreement is better than a slogan.
The sonata carries detailed dynamics — rapid f–p alternations in the first movement around bars 9–10, 12–13 and 15, and in some editions a startling p f p f p inside bar 14. A harpsichord cannot play those: its volume doesn't answer to the key. So the music demands a touch-sensitive instrument. And the marks are genuinely Haydn's — you can see f and p already in the 1771 autograph.
⚠️ Two precisions that matter. ① Those are neighbouring bars and beats, not neighbouring notes — don't overstate it. And the bar-14 group is Haydn's own: p: f: p: f: p: stands in his autograph (Paris, BnF MS-133) and in the Artaria-descended Breitkopf print of 1800 — both authentic branches. So Peters transmits Haydn; it is the 1901 Universal edition that drops it. Conversely the f at bar 9 appears in the prints but not in the autograph, so it looks like Artaria's. (If you compare editions yourself: Päsler/Breitkopf 1918 inserts a whole extra echo group in bar 11 that neither the autograph nor the older prints have.) ② The dynamics rule out the harpsichord; they do not prove fortepiano. A. Peter Brown: "it is almost certain that these sonatas were composed for the clavichord" — an instrument that is touch-sensitive and quieter than conversation. Howard Pollack argues clavichord in 1771, possibly touched up for fortepiano in 1780.
The safest sentence remains: "the dynamic markings in the sources demand a touch-sensitive instrument." And note that Haydn's own autograph heading says "per il Clavicembalo" — harpsichord — which is exactly the instrument the dynamics rule out. That contradiction, in his own hand, is the real story here.
| Movement | Tempo | Key | Metre | Form |
|---|---|---|---|---|
| I | Allegro moderato (autograph: "Moderato") | C minor | 4/4 | Sonata form · 100 bars |
| II | Andante con moto | A♭ major | 3/4 | Aria-like, over a running bass · 67 bars |
| III | Finale: Allegro | C minor | 3/4 | Sonata form (NOT a minuet!) · 152 bars |
The first subject opens quietly, in parallel thirds and sixths, then falling semitones — cool on the surface, tense underneath. Then the music travels to the second subject in E♭ major — the relative major (the standard minor-key move, i → III).
Normally a sonata-form exposition has a clean stop in the middle (a "medial caesura"). This one has no articulated one — it flows onward instead. Hepokoski and Darcy discuss this movement by name and call it "a special, Haydnesque variant of the expansion-section subtype of the continuous exposition", though they do hear "the suggestion of a light" caesura around bar 19. (Not everyone accepts the label: Lauri Suurpää expressly declines it. Say "no articulated medial caesura" and you are safe either way.)
You will see it written that "analysts disagree whether the recapitulation begins at bar 69 or bar 78." They don't. The recapitulation begins at bar 69, and nobody argues otherwise. The "78" comes from Suurpää's analysis, which divides each section into three functions — for the recapitulation, initiating 69–77, medial 78–92, concluding 93–100. Bars 69 and 78 are two adjacent labels inside one analysis, not two rival readings. (A second confusion feeds it: bar 78 is the recapitulation point of the finale.)
Here is the argument that genuinely exists, and it's a better one to bring up: where does the second subject begin? Jens Peter Larsen says bar 26. A. Peter Brown says bar 32, and Hepokoski & Darcy side with Brown; Tom Beghin has suggested it may start as early as bar 15. Three answers, all in print. And the loveliest detail: Larsen's bar 26 is exactly where "Tempo primo" resumes after the written-out Adagio and its fermata — he is hearing that flourish as the structural divide. So the cadenza isn't decoration; it may be doing the job the missing medial caesura would have done.
It reaches a real B♭ minor at bar 47, then repeats that material in E♭ minor at bar 53. Bars 56–59 are the strange part: a sequence of parallel six-four chords which, as Suurpää puts it, "lacks stable sonorities altogether" — the harmony slides rather than steps, arriving on an E♭ major six-four at bar 59. The bass then walks B♭ (59) → C (61) → D (62) to the structural dominant at bar 63.
A caution about a claim you may have read: some notes list this passage as "touching A♭ minor and G♭ major", G♭ being spectacularly remote for 1771. Careful — those are passing sonorities inside the sliding six-four sequence, not established keys. That is precisely Suurpää's point about the passage. Calling them "keys" overstates it; "unstable chromatic sonorities" is both safer and more accurate about what your ear actually hears.
Movement I contains two "quasi-cadenzas" — passages Haydn wrote out in full, marked Adagio with fermatas, that sound like an improvised solo. They come straight from C. P. E. Bach's style (concerto rhetoric inside a sonata). The slow movement does the same before its final cadence. Point at one and explain it.
A♭ major — the flat submediant (♭VI) of C minor, a warm, distant key Beethoven later loved. A singing melody unfolds over a running bass, full of syncopation that keeps it restless even at a slow tempo.
The finale sounds like a minuet (3/4, graceful opening) — but it is not a minuet and trio: it's a full sonata-form movement that grows in intensity, with virtuosic hand-crossing where the left hand leaps between the extremes of the keyboard. And it ends in C minor — with no Picardy third, no happy major chord. For 1771, refusing to end happily was a striking, almost shocking choice. That bleak ending is the expressive point of the whole sonata.
The 18th-century default is a trill starting on the upper note, on the beat (C. P. E. Bach, Türk). But Haydn's own signs are inconsistent — his single "Haydn ornament" can mean a turn or a mordent. Say what you decided and why.
Play the f and p as sudden, terraced contrasts — like flipping a switch — not as smooth crescendos. Keep the pedal out of those f–p moments: they need a dry, clean attack.
AMEB: "Repeats may be performed at the candidate's discretion, as long as all other program requirements are met." Since this sonata is most of your 25-minute floor, the exposition repeat is load-bearing arithmetic as well as musical shape. Take it, and be ready to justify the second-half repeats in terms of proportion — how much drama can the music bear? (Note the separate rule one line later: "All da capo directions must be observed.")
Two sisters, a doctor, and a publisher — and every one of them is a better story than you'd expect from a dedication page.
Leopold Auenbrugger invented percussion of the chest — the tapping a doctor still does on your back today — and published it in Vienna in 1761. The idea reportedly came from watching his father, an innkeeper, tap wine casks to hear how full they were. He listened to bodies the way you listen to a piano: by striking them and judging the resonance.
The same doctor wrote the libretto for Der Rauchfangkehrer ("The Chimney Sweep"), commissioned by Emperor Joseph II and premiered at the Burgtheater on 30 April 1781, with music by Salieri.
The younger sister wrote a Sonata per il clavicembalo o forte piano in E♭. She died in 1782, aged 23 — two years after your sonata was printed. Salieri paid out of his own pocket to publish her sonata, attaching his own funeral ode and calling himself "friend and admirer of her rare abilities."
"Both of them, and in particular the elder, play extraordinarily well and are thoroughly musical." So when Haydn says this sonata is "the longest and most difficult", he is saying it about music he expected these two to play.
Artaria were an Italian family firm from Lake Como who sold engravings, maps and art before they sold music, and set up Vienna's first music printing press in 1776. Your sonata's volume was their first Haydn publication — the start of a relationship that would later take in Mozart and Beethoven.
Haydn asked Artaria to print a notice, and they did. The Avertimento warns that two of the six sonatas begin with the same idea and that "the Author gives notice that he has done this on purpose" — a composer heading off an accusation of self-plagiarism, in print, in 1780.
The right hand has three identical ornament signs — and one old edition prints two different realisations side by side, separated by "oder:" ("or:"). An editor openly admitting defeat, in print. The manuscript settles part of the mystery: the sign there is a compound — a turn symbol stacked on a mordent zigzag, written three times over — so it is not that editors couldn't read it; the sign genuinely asks for two things at once. So when you are asked "how do you play that ornament?", the honest and impressive answer starts: "the sign is ambiguous, and here's why I chose this one."
The Andante closes in A♭ with a proper cadence and repeat dots — no attacca, no segue. So the gap is yours to shape, and the syllabus explicitly marks you on "appropriate timing between, and linking of movements." Decide how long that silence is.
The finale spans FF♯ up to f‴ — bottom to top of the whole five-octave compass. That low F♯ matters: a typical Viennese harpsichord of the day, with a short bass octave, simply did not have that note. Haydn is writing for the edges of an instrument that had only just grown them.
"The second subject arrives in E flat major, the relative major — the standard minor-key Classical scheme, i to III rather than i to v. But Haydn gets there in an unusual way: there's no articulated medial caesura, so the exposition runs on instead of stopping; Hepokoski and Darcy call it a Haydnesque variant of the continuous exposition. And that's why analysts can't agree where the second subject actually begins — Larsen says bar 26, Brown says bar 32, and bar 26 is exactly where Tempo primo resumes after the written-out Adagio, so that cadenza may be doing the structural work the caesura would have done. It's what makes the movement feel so restless — which is why I play the transition as one long forward-pressing line, and give the Adagio real weight rather than treating it as an ornament."
Why was the sonata written in 1771 but not published until 1780?
The standard answer is contractual — the 1761 Esterházy contract, the 1779 revision — but it doesn't survive scrutiny: Haydn had already authorised a public print of six other sonatas in 1774 while this one sat unpublished, and Landon calls the clause "a dead letter anyway". The better answer is compositional: the 1771 layer looks like a draft, the autograph doesn't contain the slow movement at all, and A. P. Brown suggests the first movement was simply unfinished.
Is the finale a minuet?
No — it sounds like one at the opening (3/4, graceful), but it's a full sonata-form movement that grows in intensity with virtuosic hand-crossing, and ends in the minor.
What key is the slow movement in, and what relationship is that?
A♭ major — the flat submediant (♭VI) of C minor, a warm, remote key Beethoven later loved.
