Piano scale fingering is which fingers play which keys in a scale: the right hand plays C major ascending with 1, 2, 3, 1, 2, 3, 4, 5, with the thumb crossing under after the 3rd finger, and the left hand plays it with 5, 4, 3, 2, 1, 3, 2, 1, with the 3rd finger crossing over the thumb.
What is piano scale fingering?
Piano scale fingering is which fingers play which keys in a scale: the right hand plays C major ascending with 1, 2, 3, 1, 2, 3, 4, 5, with the thumb crossing under after the 3rd finger, and the left hand plays it with 5, 4, 3, 2, 1, 3, 2, 1, with the 3rd finger crossing over the thumb. The fingering lets the hand play the scale smoothly, without stopping, because the thumb crosses under, and the hand moves, and the scale flows, from one octave to the next, and the fingers are the map, on the keyboard. The scale fingering is the same for every scale, with the thumb crossing under, and the fingers crossing over, and the pattern is the same, because the hand is the same, and the keyboard is the same, and the fingering is the hand, fitting the scale, and the scale is the notes, in order, and the fingering is the way to play them, smoothly, without stopping, and without the hand getting stuck. The C major scale and the G major scale are the scales most players first finger, and the piano note finder shows the notes on the piano.
How piano scale fingering works
Piano scale fingering works by crossing the thumb under, and the fingers over, so the hand can play more notes than it has fingers, and the scale can go on, for octaves, without stopping. The right hand plays C major ascending with 1, 2, 3, 1, 2, 3, 4, 5: the thumb plays C, the index plays D, the middle plays E, and then the thumb crosses under, to play F, and the index plays G, the middle plays A, the ring plays B, and the pinky plays C, an octave higher, and the thumb crossing under is the key, because it lets the hand move, without lifting, and the scale flows. The left hand plays C major ascending with 5, 4, 3, 2, 1, 3, 2, 1: the pinky plays C, the ring plays D, the middle plays E, the index plays F, the thumb plays G, and then the middle finger crosses over the thumb, to play A, and the index plays B, and the thumb plays C, an octave higher, and the finger crossing over is the key, because it lets the hand move, without lifting. The thumb crossing under is the hardest part, because the thumb must move under the hand, quickly and smoothly, without the hand lifting, and the hand must stay level, and the wrist must stay relaxed, and the fingers must be curved, and the thumb must land on the right key, F, in C major, and the scale must not stop, and the fingering must be practised slowly, until it is smooth, and then the speed can increase. The D major scale and the A major scale are the scales the fingering is built on, and the key of C major has no sharps or flats, so it is the easiest scale to finger.
Worked example — fingering the C major scale. Put your right hand on the piano, with the thumb, finger 1, on C, middle C, C4, 261.63 Hz, and play the scale ascending: thumb on C, index on D, middle on E, and then cross the thumb under, to F, and play G with the index, A with the middle, B with the ring, and C with the pinky, an octave higher, C5, 523.25 Hz, and the fingering is 1, 2, 3, 1, 2, 3, 4, 5, and the scale is C major, played smoothly, without stopping, because the thumb crossed under. Now put your left hand on the piano, with the pinky, finger 5, on C, C3, 130.81 Hz, and play the scale ascending: pinky on C, ring on D, middle on E, index on F, thumb on G, and then cross the middle finger over the thumb, to A, and play B with the index, and C with the thumb, an octave higher, C4, 261.63 Hz, and the fingering is 5, 4, 3, 2, 1, 3, 2, 1, and the scale is C major, played smoothly, because the middle finger crossed over. The I–V–vi–IV progression in C major is a good progression to practise the scales with.
How to practise piano scale fingering
Practise scale fingering slowly, with a metronome, until the thumb crossing is smooth, and the scale flows, and then increase the speed, one step at a time.
- Play the C major scale with the right hand, ascending, fingering 1, 2, 3, 1, 2, 3, 4, 5, and listen for the scale to flow, without stopping, at the thumb crossing.
- Play the C major scale with the left hand, ascending, fingering 5, 4, 3, 2, 1, 3, 2, 1, and listen for the scale to flow, without stopping, at the finger crossing.
- Play the scale descending, with the fingering reversed, and listen for the scale to flow, without stopping, at the crossings.
- Play the I–V–vi–IV progression in C major and play the scale of each chord, with the right fingering, and listen for the scales to be smooth.
- Practise with the metronome at 60 beats per minute, and increase the tempo by 5 beats per minute when the fingering is clean at the current tempo.
Common mistakes
- Lifting the hand at the thumb crossing — A hand that lifts at the thumb crossing will stop the scale, because the hand must move, and the thumb must cross under, without the hand lifting, and the scale will be choppy, not smooth. Keep the hand level, and let the thumb cross under, quickly and smoothly, without lifting.
- Using the wrong fingers — The fingering is 1, 2, 3, 1, 2, 3, 4, 5, for the right hand, and 5, 4, 3, 2, 1, 3, 2, 1, for the left hand, and using the wrong fingers will make the scale hard to play, and the crossings will be in the wrong place. Use the fingers the fingering shows, and the scale will be smooth.
- Practising too fast, too soon — A scale practised too fast, too soon, will have mistakes, because the fingers are not ready, and the crossings are not smooth, and the mistakes will become habits, because they are practised. Practise slowly, until the fingering is clean, and then increase the speed, with the metronome.
Quick reference
This table shows the fingering for the C major scale, for the right hand and the left hand, ascending and descending, so you can see the fingering side by side and practise it one hand at a time. The thumb crosses under in the right hand, and the 3rd finger crosses over in the left hand, and the fingering is the map, on the keyboard.
| Hand | Direction | Fingering |
|---|---|---|
| Right hand | Ascending | 1 – 2 – 3 – 1 – 2 – 3 – 4 – 5 |
| Right hand | Descending | 5 – 4 – 3 – 2 – 1 – 3 – 2 – 1 |
| Left hand | Ascending | 5 – 4 – 3 – 2 – 1 – 3 – 2 – 1 |
| Left hand | Descending | 1 – 2 – 3 – 1 – 2 – 3 – 4 – 5 |
Use the table to practise the fingering: play the scale ascending and descending, with each hand, and listen for the scale to flow, without stopping, at the crossings, and the thumb to cross under smoothly. When you can play the scale, in both hands, at 120 beats per minute, you have the fingering, and the scale is yours.
Frequently asked questions
What is piano scale fingering?
Piano scale fingering is which fingers play which keys in a scale: the right hand plays C major ascending with 1, 2, 3, 1, 2, 3, 4, 5, with the thumb crossing under after the 3rd finger, and the left hand plays it with 5, 4, 3, 2, 1, 3, 2, 1, with the 3rd finger crossing over the thumb.
Why does the thumb cross under in a scale?
Because the hand has five fingers, and the scale has eight notes, so the thumb must cross under, to play more notes than the hand has fingers, and the scale can go on, for octaves, without stopping, and the fingering is the way to play them, smoothly.
What is the fingering for the C major scale, right hand?
Ascending, 1, 2, 3, 1, 2, 3, 4, 5, with the thumb crossing under after the 3rd finger, to play F, and the pinky playing C, an octave higher, and descending, 5, 4, 3, 2, 1, 3, 2, 1, with the thumb crossing under after the 1st finger.
What is the fingering for the C major scale, left hand?
Ascending, 5, 4, 3, 2, 1, 3, 2, 1, with the 3rd finger crossing over the thumb, after the thumb plays G, to play A, and descending, 1, 2, 3, 1, 2, 3, 4, 5, with the 3rd finger crossing over the thumb.
Is the fingering the same for every scale?
Mostly, yes. The thumb crossing is the same, and the pattern is the same, because the hand is the same, and the keyboard is the same, but the fingering changes for scales with black keys, because the thumb should not play a black key, and the fingers must fit the scale.
