Observations on Mozart
As we know, a musical composition does not by nature have the presence of a picture, a sculpture, a novel, or a movie. It lays dormant in the score and needs to be made audible. It is the performer’s obligation to kiss it awake. “Bring the works to life without violating them,” was Edwin Fischer’s advice.
First, I’d like to explain what Mozart means to me. He is certainly not the charmingly restricted Rococo boy wonder that he may have appeared to be some hundred years ago. I consider him one of the very greatest musicians in the comprehensive humanity of his da Ponte operas, in the universe of his piano concertos, in his string quintets (which are matched only by those of Schubert), in his concert arias and his last symphonies. For the pianist, his piano concertos are one of the peaks of the repertoire; they reach from tenderness and affection to the border of the demonic, from wit to tragedy.
How may we characterize Mozart’s music? Considering the character of a composer, we are prone to assuming that the person and the composer are an equation. Yet the music of a great composer transcends the personal. There is a mysterious contradiction: while the person is clearly limited, the mastery and the expressive force of the great musician is well-nigh unlimited. In his work, Mozart, according to Busoni, presents the solution with the riddle. Among Busoni’s Mozart aphorisms, we find the following: “He is able to say a great many things, but he never says too much.” And: “His means are uncommonly copious, but he never overspends.” To find such a measure of perfection within a great composer is particularly rare as it is usually the followers, the minor masters, who smooth out whatever the great ones have offered in ruggedness and uncouthness.
Not that his contemporaries noticed such perfection. Time and again, they considered his music to be unnatural, full of unnecessary complication and unreasonable contrast. The exception was Haydn, who pronounced Mozart to be the greatest of all composers.
We find amazing boldness particularly in late Mozart. Think of the second movement of his F major Sonata KV 533, or the beginning of the development section in the G minor Symphony’s finale. It would be a mistake to exaggerate such passages in performance — they speak for themselves. The transitional bars in the G minor Symphony almost amount to a twelve-tone row — there is just one note missing (the G).
In my contemplation of Mozart, I like to start not with musical speech but with singing. Once more, Busoni finds the right words: “Unmistakably, Mozart’s music proceeds from singing, which results in an unceasing melodic production that shimmers through his compositions like the beautiful female contours through the folds of a light dress.” Mozart was a cantabile composer. Not unreasonably, he bears the reputation of being the greatest inventor of melodies next to Schubert. (Permit me to mention in this context a third name, that of Handel.) We can only register with astonishment the fact that there were contemporaries who complained about a lack of cantabile in Mozart’s operas. The operatic traits in his piano concertos, the characterizing incisiveness of many of his themes have been frequently noted.
Not without good reason, the pianist Andras Schiff has called Mozart’s concertos a combination of opera, symphony, chamber music, and piano music. There we imagine a singer singing, but the operatic also includes the characters embodied on stage, the action of temperaments, the lifeblood. The pianist, like the singers, operates within a firm musical frame. Mozart, in his letters, describes his rubato playing as occurring within a firm rhythmical scheme. To be sure, there also will be some modifications of tempo, but they should remain conductible. I know there were scarcely conductors in Mozart’s time. Tempi therefore had to be stricter, you had to play together, and one could often not expect more than one run-through rehearsal, if any. Performances in Haydn’s or Mozart’s time must have been quite different from what we expect today — a rather cursory experience, a rough outline of a work without the refinement of a well-studied concert.
In Mozart’s correspondence, singing and cantabile are frequently mentioned. How does one sing on the piano? Continuous finger legato is not the answer. Singing has to be articulated. We know that the piano literature offers examples of cantabile passages played by the thumb or the fifth finger. Here and elsewhere, the pedal will be of considerable assistance. I know there are pedal purists. I am not one of them.
Cantabile calls for continuity. Mozart’s father Leopold, one of the leading musical authorities of the eighteenth century, writes in his Treatise on the Fundamental Rules of Violin Playing, known as the Violin School: “A singer who would pause with every little figure, breathe in, and perform this or that note in a particular fashion would unfailingly provoke laughter. The human voice pulls itself spontaneously from one note to the next… And who doesn’t know that vocal music should at all times be the focus of attention of all instrumentalists for the sake of being as natural as possible?” According to Mozart’s father, the bow should remain on the violin wherever there is no real break, so that one bowing can be connected with the next. (Leopold Mozart’s Violin School appeared first in 1756, the year Wolfgang was born. My citations are from the third edition, published in 1787.)
Evidently, an all-too-fragmented delivery that dissects the cohesion of the music will not do justice to this ideal. Which doesn’t mean that we may ignore Mozart’s articulation marks at will. I have always done my best to respect them all.
Cantabile themes are most likely happening in the piano’s upper middle range. This is one of the reasons why I prefer the modern piano to a Hammerklavier, notwithstanding the peculiar charms of the older instrument. On our pianos, the sound is longer and lends itself better to singing, in case the pianist feels the inner urge to make it sing.
Already around 1800, Mozart was compared to Raphael, a favourite artist of the nineteenth century, but also to Shakespeare. The German Romantic writers Tieck and Wackenroder enjoyed spreading such ideas. I readily subscribe to the Shakespeare parallel on account of Mozart’s da Ponte operas. The tombstone of the great French writer and melomane Stendhal testifies for his veneration of Mozart and Shakespeare, with Cimarosa added for good measure.
The equation with Raphael is another matter: it shows how much the perception of this revered Renaissance master, but also of Mozart, has since changed. Here is what Wackenroder writes about Raphael: “It is obviously the right naivety of mind that observes the poorest and darkest lot of human destinies in a light and jocular manner, facing the most deplorable misery of life with an inner smile.” A similar image of Mozart has dominated for quite a while. Nothing seems easier than to launch dogmatic ideas; like infectious diseases, they spread in no time, and remain difficult to eliminate.
In connection with a performance of Haydn’s Creation, Goethe and Zelter called naivety and irony the hallmarks of genius, a distinction that should be equally valid at least for part of Mozart’s personality.
I see Mozart’s piano concertos not only as the pinnacle of the species but as one of the summits of all music. Already in his Concerto in E flat KV 271, written in 1777 when he was twenty-one years old, Mozart gives us a masterpiece of a distinction that he had not reached before and hardly would surpass after. It was only with his Sinfonia Concertante KV 364 that he connects to it. The C minor Andante remains one of his greatest slow movements. In it, Gluck’s loftiness is elevated to Mozart’s heights.
Among the later piano concertos, the two works in minor keys occupy a different ground. Mozart in minor seems to me almost a changed personality. Both first movements are composed in a procedural manner while elsewhere Mozart prefers to string together his themes and ideas like ready-mades. (He does it with such immaculate seamlessness that it appears it couldn’t be otherwise.) Mozart’s concertos reach from the private to the most official (as in KV 503), and from the loving to the fatefulness of KV 466 and KV 491.
The significance of his piano sonatas dawned on me much later. Here, another of Busoni’s aphorisms seems to fit: “He neither remained simple, nor did he turn out to be overrefined.” It may still be useful to point out that Mozart is not easier to play because he presents fewer notes, chords and bravura passages. Possibly “the experience of the player has to pass through an infinite” — as in Heinrich von Kleist’s “Essay on the Marionette Theatre” — “before gracefulness reappears.” Artur Schnabel’s remarks on Mozart’s sonatas are well-known: “Too easy for children, too difficult for artists”; or, in a different wording, “children find Mozart sonatas easy thanks to the quantity of the notes, artists difficult due to their quality.” Mozart is so demanding because each note, each nuance, counts and everything lies bare, particularly in the utmost reduction of the piano sonatas. You cannot hide anything.
In addition, mere piano playing is not enough. While in the concertos the piano sound needs to clearly stand out against that of the orchestra, in the sonatas it frequently acts as a proxy. If we look at his A minor Sonata KV310 — again a piece from another world — we perceive the first movement as an orchestral piece, the second as a scene from an opera seria with a dramatic middle section, and the third as music for wind instruments. (I have, by the way, heard the first movement of this work frequently played presto while it bears the tempo marking allegro maestoso. Leopold Mozart, in his explanation of musical terms, characterizes “maestoso” as “with majesty, deliberate, not precipitated”.) The famous A major Sonata KV331 also appears to me orchestrally conceived. For the “Turkish March”, Mozart would have enjoyed the cymbalom pedal that some Biedermeier pianos presented a few decades later. The Sonata in C minor KV457, as well as the Fantasy KV475, show many orchestral features as well: two marvelous, autonomous works which I would not perform consecutively. (Here I know myself in agreement with Fischer and Schnabel.) Thirty years later a number of orchestral versions of both works were published, one of them produced by Mozart’s pupil Ignatz von Seyfried.
Mozart’s notation offers extremes hardly encountered elsewhere. It reaches from the completeness of the Jenamy Concerto KV271 to the near-absence of performing instructions in works not prepared for the engraver. In KV271, there seems to be nothing that needs to be added. In contrast, the overly rich markings of Mozart’s solo works in minor keys pose a challenge to the player’s sensitivity and understanding. While the autograph of the superb C minor Concerto shows a hurried hand, it contains a number of variants but also errors and some incompleteness. In contrast to Mozart’s orchestral and chamber music works and their meticulous dynamic markings, the performance of some of the piano sonatas is left to the player’s tastes. Here a different kind of empathy is required, an identification with the composer that should enable the performer to supplement the dynamics in Mozart’s style.
The warrant of a Mozart player considerably surpasses that of a museum clerk. Where Mozart’s notation is incomplete, the written notes should be supplemented: by filling (when Mozart’s manuscript is limited to sketchy indications); by variants (when relatively simple themes return several times without Mozart having varied them himself); by embellishments (when the player is entrusted with a melodic outline to be decorated); by re-entry fermatas (which start on the dominant and must be connected to the subsequent tonic); and by cadenzas (which lead from the six-four chord to the concluding tutti). Mozart’s own variants, embellishments, lead-ins, and cadenzas — of which, to our good fortune, he left a considerable number — give the player a clear idea of his room for maneuver: in lead-ins and cadenzas the basic key is never left, in embellishments and variants the basic character is always maintained. (No transgressions like those by Hummel and Philipp Carl Hoffmann!) It is a pity that original cadenzas for the minor key concertos are missing, his cadenzas in major hardly being indicative, as the different compositional process of these works seem to demand composed-through cadenzas like the one of Bach’s Fifth Brandenburg Concerto that leads from the six-four chord to the orchestra in one sweep.
Embellishments that contradict the basic character of the movement need to be avoided. After all, simplicity and clarity can characterize a piece as well. Sometimes Mozart makes do with highly economical alterations, as in the recapitulations of the first four bars of the scene of KV491’s middle movement. Here to do more would be a misunderstanding.
In the slow movement of the so-called Coronation Concerto, on the other hand, the extremely simple and frequently recurring first bars of the theme crave embellishment. This movement is hardly more than a vehicle for the player’s extemporizing gifts. The left hand of this movement, by the way, is only elusively written down.
In the Adagio of the A major Concerto KV488, I see two possibilities: to keep embellishment to a minimum, imagining a woman singer singing the long notes, or to remember the copiously ornamented version published by the Bärenreiter Edition’s critical resumé. It seems to have belonged to Mozart’s estate, though it was written not by Mozart himself but by his esteemed pupil Barbara Ployer, providing evidence that embellishment may be called for.
It should be noted that, for good reason, orchestral and chamber music does not feature improvised variants. Why, we may ask ourselves, should the listener and player necessarily feel bored by hearing the same notes played again? When dealing with a melodist of the highest order, wouldn’t it be desirable to play a theme so convincingly that the listener would be happy to encounter it again? Wouldn’t it suffice that the performance is slightly modified? Expertise in elaboration may have the effect that the attention of the listener is focused more on the performer than on the music: see how brilliant I am! Here is another quotation from Leopold Mozart: “Some think that they produce wonders when, in an adagio cantabile, they thoroughly curl up the notes, and turn one single note into a few dozen. Such musical butchers show their lack of discrimination, shivering when they need to sustain a long note or play a few of them in cantabile fashion without applying their ordinary and awkward embellishment.”
The questions to ask are: What does the work need? How much can a work take? What is harmful to a work? While C.P.E. Bach pronounced embellishing to be one of the crucial features of interpretation, we are hardly able to agree with him today. Simplicity easily gets confused with a lack of imagination. For me, inspired simplicity is one of the most precious qualities. Whoever is interested in moving the listener will not discount it. How many of us would be able to remember a theme and its elaboration after one hearing? Constant embellishment, the ceaseless ambition to prove oneself, can become a burden under which a piece of music is crushed.
Not everything that is suggested by historicizing performance practice is relevant for us today. We are not people of the eighteenth century. Since my young years, Mozart performances have changed considerably. Some conductors and orchestras, but also chamber musicians and soloists, have adopted things that no one would have imagined some decades ago. Baroque performance practice has spilled over to the music of the late eighteenth century. Among the most remarkable gains were the correct execution of appoggiaturas: countless wrong notes have been righted in opera alone. Some other performance habits, on the other hand, deserve a critical evaluation. The majority of them are occasionally valid. Where they are applied in a dogmatic way, however, resistance is called for. Music is too diverse to be left, in its execution, to simplifying recipes. Each case needs to be judged on its own merits. It may come to a surprise to some people that the effect of a musical performance is no less determined by the detail than by the vision of the whole.
The point of departure of a performance should not be, in my view, textbooks of interpretation — textbooks that frequently are connected to a certain time and place are rarely original from most composers — but rather the fact that each masterpiece contributes something new to the musical experience, that each theme, each coherent musical idea, differs from any other. What we need to observe are not just the similarities (they are easier to spot) but the differences, the diversity, the quality that is particular to a musical idea, and exclusively so. As for the technical demands, we can say that a few recipes and established habits will not suffice. The suitable technical solution has to be found for each single case. There is no limit to discovery.
Among the habits that have been spreading dogmatically there is the striking accentuation in two-note groups with a strongly accented first note and a soft and short second. I should also mention the compulsion to play whole phrases, repeated staccato notes, and even decisive endings of movements diminuendo; the separation of small units – an overreaction against the “big line” that combines such units; the short clipping of end notes; or the separation of final chords, that are only played after a hiatus. Most of these practices have their justifications as long as they are not applied in a dogmatic and automatic way. They are sometimes right. Two-note groups with a hard-driven first note are never right. I have heard performances where such accents have been routinely exaggerated to such a degree that they sounded like the main purpose of the composition. There are, on the other hand, emotionally charged words like Dio! or Morte! that call for an accent that is expressive without being stiff.
If a number of two-note groups are linked in a chain, the emphasis should stay with the second note. If two-note groups are draped around one note, this central note deserves to be slightly emphasized. Where, in the composer’s notation, the second note is shortened by a rest, the curtailed note needs to stand out! We can still find this kind of notation in Schubert (for example, in the Finale of the A major Sonata D959).
The advice to accentuate heavy beats is so simpleminded that it seems hard to explain how it ever found its way into serious musical textbooks. Franz Liszt called it “discharging potatoes.” The saying, “If I only could afford it, I would print all music without bar lines!”, comes from Artur Schnabel. My own experience tells me that one of the hallmarks of a good Mozart performance consists precisely in avoiding accented heavy beats, and even counteracting them, provided that they aren’t dealing with marches or dances. Besides dancing and stamping, music, after all, is entitled to be able to float.
The way long notes are executed can strongly contribute to the flavor of a performance. If we look at Baroque instruments, there are several possibilities. The organ will maintain them in continuous loudness. An oboe renders them cantabile. The harpsichord starts each note with an accent. Strings and the human voice can modify their approach. Long notes should often sustain the musical tension and carry it on. If they are rendered abbreviated or without vibrato, they will hardly be able to do so. A good oboist will often play them most naturally. To play such notes routinely diminuendo or to start the note without vibrato and vibrate later (a mannerism some singers have adopted as well) I find neither necessary nor desirable. Edwin Fischer demonstrated that long notes can be sustained on the modern piano without noticeable accent. Here the quality of the instrument should also matter.
There are musicians who believe that a historicizing approach will bring you closest to a piece. What is called for, they claim, is a different way of listening. The listening experience that has formed us is an obstacle that has to be discarded. I am not ready to be that radical. Even if it were conceivable to return a work to its original meaning and condition, would this really solve the problem of performance?
The most important criteria remain that the piece should impress, move, and entertain. We cannot and should not discard what we have held precious. There are things that I find unacceptable, such as long notes without vibrato — a crass offense against cantabile — or the routine of equating pianissimo with non-vibrato in the belief that the timbre thus produced strikes one as mysterious and uncanny. No, the sound is merely deprived of any color, it is cold and dead.
A singer who sings naturally will do this with a vibrating voice, and even with very fast vibrato — think of Lotte Lehmann or Kathleen Ferrier. These days, fast vibrato is unpopular. But shouldn’t the whole range of vibrato be at a singer’s or string player’s command? The use of vibrato is documented since 1600, both for singers and string players.
It is precisely as a pianist that I want to plead for singing. These days, in the wake of historicizing performance practice, cantabile has widely fallen into oblivion. Within my understanding of music, however, singing, at least before the twentieth century, is at the heart of music.
It doesn’t tally with my experience that old masterpieces only sound beautiful and persuasive when performed on old instruments. There is, on the other hand, music that I wouldn’t like to hear on modern ones anymore. To listen to Monteverdi on the instruments of his time was a liberation, and two Scarlatti recitals by Ralph Kirkpatrick convinced me that the harpsichord is indispensable for this remarkable composer. Permit me to quote Nikolaus Harnoncourt: “How did they do it at the time? What may the sound have been like? There will, however, be hardly a musician who would make a profession out of this kind of quest – I would call such a person a historian. A musician will ultimately look for the instrument that is most useful to himself. I would therefore like to restrict my observations to those musicians who prefer certain instruments for purely musical reasons; those who do it merely out of interest for old facts and circumstances, do not count for me as musicians. They may, in the best case, be scientists, but not performers.” Here one can only agree with Harnoncourt.
Whoever insists on old instruments should remember that some of the great composers have frequently transcribed works of their own or those of other composers, such as Bach transcribing Vivaldi, or a work for solo violin turning into his famous Organ Toccata and Fugue in D minor. (As there is no contemporary source for this piece, it may have been done by a later composer. In its toccata, the work persists in one single voice, while the fugue takes consideration of the technical limits of the violin.) A transcribed violin version was performed by Sigiswald Kuijken.
Only gradually did musical performances become accessible to a wider public. Concert venues expanded in size. This asked for more powerful string and keyboard instruments. While the sound of instruments with gut strings can have a particular charm, it will be too restricted for modern halls. When we look into a score we would, after all, be happy to hear what is written down. The power of the wind players used to easily drown out the strings. Only rarely would the composer have been provided with the multitude of first violins that would have enabled a proper balance with the winds. It is the first violins that frequently carry the main voice.
Here is another statement by Harnoncourt: “The composer thinks unquestionably in the sounds of his time and by no means in some future ‘utopias’.” This may be correct in many cases. When, however, I think of most later Schubert sonatas, and of his Wandererfantasie in particular, works that turned the piano into an orchestra, the ideal possibilities of that performance surpass by far what his contemporary instruments had to offer. Broadly speaking, I would say this: a composer may compose on, but not for, the piano which graces his music room.
I have no doubt that Mozart’s music is often better served by a good pianoforte than by the fortepiano. Proceeding from his operas, orchestral works, and chamber music, we are bound to notice that the wider range of color and dynamics will do better justice to Mozart’s requirements. As a rhythmical model as well, the orchestra and ensemble playing should give us a better example than a manner of performance that has lost the firm ground under its feet. Here is Leopold Mozart’s amazing dictum: “The pulse makes the melody: therefore it is the soul of music. Not only is it enlivened by it, it also keeps all its limbs in good order.”
Permit me, in conclusion, to return to the character of Mozart’s music and quote what I wrote in my younger years in order to specify what Mozart was not: “Mozart is made neither of porcelain, nor of marble, nor of sugar. The cute Mozart, the perfumed Mozart, the permanently ecstatic Mozart, the ‘touch-me-not’-Mozart, the sentimentally bloated Mozart, must all be avoided. There should be some slight doubt too about a Mozart who is incessantly ‘poetic.’ ‘Poetic players’ may find themselves sitting in a hothouse into which no fresh air can enter; you want to come and open the windows. Let poetry be the spice, not the main course. A Mozart who combines sensitivity and fresh air, temperament and control, accuracy and freedom, rapture and shudder in equal measure, may be utopian. Let us try to come near to it.”
