Piano finger numbers and how to choose fingering

How piano finger numbers work

Each hand is numbered from the thumb outwards: 1 is the thumb, 2 the index finger, 3 the middle finger, 4 the ring finger and 5 the little finger. The same numbers are used for both hands, which means the hands are mirror images. Put both hands on the keyboard in a C position and the right hand’s thumb is on the lowest note, middle C, while the left hand’s 5 is on the lowest note, the C below.

That mirroring confuses most beginners for a week or so. A pattern that goes 1 2 3 4 5 in the right hand climbs up the keyboard; the same numbers in the left hand walk down it. If you mix the hands up, say the numbers out loud while you wiggle each finger, one hand at a time, until it’s automatic.

Where fingering appears in sheet music

Fingering is printed as small numbers next to the notes. In most editions they sit above the notes of the right hand and below the notes of the left hand, though editors move them when there isn’t room. For a chord, the numbers are stacked in the same order as the notes. Two numbers joined by a dash or a small curve over one note, such as 3–1, mean a finger change on that note: play it with 3, then swap to 1 while the key is held down.

You won’t see a number on every note. Editors write fingering where it matters, usually at the start of a passage, where the hand moves, and at awkward places. Between the numbers, keep going in the obvious way: if the first note says 1 and the notes step up, the next ones are 2, 3 and so on.

Five-finger positions

Most beginner music sits in five-finger positions: each finger over its own key, five neighbouring notes under one hand. In C position the right hand covers C D E F G. In G position it covers G A B C D. While the music stays in a position you hardly need fingering at all, because each note has its own finger.

Fingering becomes a real question when the music goes beyond five notes, or comes back past where it started. That’s when you have to decide where the hand moves, and the rest of this guide is about making that decision well.

How to choose piano fingering

There is rarely only one right answer, but good fingerings share some principles. Here they are in roughly the order a teacher would think about them.

1. Stay in one position as long as you can. Every move of the hand is a chance to land in the wrong place, so a fingering that covers a whole phrase from one position is usually best.
2. Move at natural breaks. When the hand must move, move it where the music lets you: at a rest, the end of a phrase, a long note, or a repeated note. A shift in the middle of a quick legato line is much harder to hide.
3. Use thumb under and finger over for runs. To go further than five notes without a jump, the thumb passes under the hand going outwards, and a finger crosses over the thumb coming back. This is how scales work, and the C major scale is the clearest example.
4. Keep the thumb off black keys in quick passages when a comfortable alternative exists. The thumb is short and sits low, so on a black key it pulls the whole hand forward. In chords and slow music it’s often fine.
5. Look ahead. The next notes decide the fingering of this one. Before you choose a finger for a note, look at where the line goes over the next few notes, and pick the finger that leaves room for them.
6. Change fingers on fast repeated notes. For a quick run of the same note, 3 2 1 (or 4 3 2 1) on one key is easier to play evenly than one finger bouncing. Slow repeated notes can use the same finger.
7. Choose once, then use it every time. Your hands learn a passage as a sequence of movements. A different fingering each time means learning it again each time. Write your choice in pencil above the notes.

Scales are the best way to make thumb under and finger over feel natural, because the same crossing comes up again and again. See how to practise scales for a routine, and the C major scale page for both hands written out. Pianomi’s scales and arpeggios show the standard fingering in the music as you play.

A worked example: looking ahead

Take a right-hand phrase that goes C D E F G A G F E D C. If you start on C with your thumb and simply count up, 1 2 3 4 5, you reach G with your little finger and have nothing left for A. The A is what decides the fingering of the first note.

There are a few ways round it. You could play it like a scale: 1 2 3 on C D E, thumb under to F, 2 3 on G A, back down 2 1 on G F, then 3 crosses over to E, and 2 1 on D C. Or, if the phrase has a rest or a long note before it, you could start the hand somewhere else. Both are good; what matters is that you notice the A before you start, not when you get there. That habit, reading a few notes ahead to plan your fingers, is the same one that makes reading ahead work.

Editions’ fingerings are suggestions

The fingering printed in your music was chosen by an editor, for a typical hand. It’s usually a good starting point, and worth trying properly before you change it. But hands differ. A player with a large hand may stretch where a smaller hand has to move, and different editions of the same piece often finger it differently.

If a printed fingering keeps feeling awkward after a few slow tries, try one or two alternatives, choose the one that works for you at the full tempo, and write it in. A teacher can help here: they’ll often spot a fingering problem before it becomes a habit.

Fingering when you learn a new piece

Decide the fingering at the very start, before you play the passage up to speed. Work out each hand separately, slowly, a phrase at a time, and pencil in numbers wherever the hand moves or the choice wasn’t obvious. It feels slow, but it’s much faster than unlearning a fingering you’ve already practised fifty times. There’s more on this in how to learn piano pieces faster, and simple finger exercises help each finger answer to its number quickly. If you’re still setting up, start with hand position and posture.
