Fingering is an artistic decision

A student brings me a Chopin nocturne and the same bar collapses every week, always in the same place, always with the same small apology afterwards. We slow it down, we repeat it, we try again the following week — and it collapses again. Then we look at the numbers printed above the notes, change two of them, and the passage plays itself. Nothing about the student's technique improved in those thirty seconds. What changed was a decision that had been made years earlier by an editor who never met that hand. Fingering is the most underestimated choice in piano playing: students treat it as a matter of comfort, or as something already settled by the edition on the stand, when in fact it is one of the few places where a technical decision and a musical decision are the same decision.

The numbers in the score are a suggestion

It helps to know where printed fingerings come from. Most editions carry the choices of an editor, often a fine pianist, sometimes working a century ago, and always working with their own hand, their own instrument and their own idea of the piece. In a good urtext you will often find the composer's few original indications printed differently from the editor's, and those two sets can disagree openly. This is not a reason to ignore the page — a printed fingering is an experienced first draft and usually deserves to be tried first. But it is a reason to stop treating it as the answer. When I ask a student why they use a particular fingering, the most common reply is "because it says so", and that is the moment the passage stops being theirs. The alternative is not chaos. It is a decision you can defend in one sentence.

First principle: fingering should serve the phrase

Ask first what the passage is meant to sound like, and only then which fingers can produce it. A line that must be seamlessly legato may need a silent finger substitution on a held note rather than a leap the hand can only make by lifting. A melodic peak carries better on a strong third or fourth finger than on a thumb arriving from underneath, because the thumb tends to land with a weight and a colour of its own. A phrase that has to breathe between two groups is easier if the fingering itself breaks there, so the hand's natural reset happens exactly where the music wants a comma. This is what I mean by accuracy: not "does it get the right notes" — many fingerings do that — but "does it make the sound I want easy rather than heroic". A fingering that requires courage is the wrong fingering. Under concert conditions, courage is the first thing to leave the room.

Second principle: keep flexibility, and test at tempo

A fingering that works beautifully at half speed can fall apart at full speed, because slow playing hides how far the hand actually has to travel. So test every choice in the tempo it will be performed in, early, before it has been repeated two hundred times. It is also worth accepting that a passage may want different solutions in different circumstances — the same figure can take one fingering when it needs to be brilliant and another when it must be soft, and repeated material in a recapitulation sometimes deserves a different hand position than it had the first time, because the context around it has changed. The point is not to keep changing your mind; it is to make the choice consciously, and to keep the flexibility to solve a wide-position figure by redistributing notes between the two hands, which is entirely legitimate and much more common in professional playing than students imagine.

Third principle: your hand is not the editor's hand

Hands differ more than any edition can account for. Span, the relative length of the fourth and fifth fingers, thumb flexibility, the width of the palm — all of these change what is reachable and what is merely possible with strain. A pianist with a small hand should not spend a year forcing a stretch that a wider hand takes for granted; the intelligent solution is usually to break the chord slightly, redistribute a note to the other hand, or use the pedal to hold what the fingers cannot. Equally, a large hand may find the printed fingering cramped and do better with a wider, calmer distribution. None of this is cheating. The audience hears the sound, not the numbers, and a fingering chosen for the hand that is actually playing will always produce a freer, better-sounding result than one imposed on it. If a fingering makes you tense at your own instrument, that is real information — not a character flaw.

Decide it, write it, then keep it

Here is the routine I ask students to use. Take the difficult passage, play it slowly while thinking about the sound you want, then try the printed fingering, one alternative, and if needed a third. Play each version at the real tempo twice. Choose the one that makes the intended sound the easiest, and write it in the score in pencil — including the obvious bits, because "obvious" disappears under stress. Then keep it. The most common cause of memory slips is not a difficult fingering but an inconsistent one: a hand that has learned two competing versions will hesitate for a fraction of a second on stage, and that fraction is where things go wrong. Decide early, before the passage is memorised, because rewriting a fingering after a hundred repetitions costs far more than choosing well at the beginning.

Fingering rewards the kind of thinking that most students postpone. It takes ten minutes at the start of learning a piece and saves weeks later; it turns a passage you fear into a passage you simply play; and it is a genuine act of interpretation, because deciding which finger arrives on the top note is deciding how that note will sound. So next time a bar keeps failing, before you repeat it once more, look at the numbers. There is a good chance the problem is not your hand at all — only the plan it was given.
