Piano Scale Fingering

How to use it

1. Pick the scale type: major, natural minor, harmonic minor or melodic minor.
2. Choose the key, the hand (right, left or both) and one or two octaves.
3. Read the numbers above (right hand) or below (left hand) each note on the staff, then find the same numbers on the keyboard under it.
4. Look for the circled numbers. They mark the thumb crossings, the moments where the hand has to move.
5. Press Play the scale to hear it, then play along slowly with each hand alone before putting the hands together.

The rules behind the numbers

Piano scale fingering follows a few simple rules. The thumb and the little finger are short, so they stay on white keys. The long fingers, 2, 3 and 4, reach the black keys. A scale is then split into groups of fingers separated by thumb crossings, so that the hand never has to stretch beyond five notes at a time.

In the right hand going up, the thumb passes under the 3rd or 4th finger. In the left hand going up, the 3rd or 4th finger passes over the thumb. Going down, each move reverses: the right hand crosses a finger over the thumb, the left hand tucks the thumb under.

Because the pattern repeats every octave, two-octave fingering is the one-octave pattern played twice. The right hand usually finishes on the 5th finger at the top. In the flat keys it finishes on 3 or 4, and in F major it finishes on 4 after one octave and 5 after two.

Fingering for the white-key scales

Scales with many black keys

Scales with many sharps or flats look harder but have a clear logic. In B major, F-sharp major and D-flat major, the thumb falls on the white keys inside the scale (E and B, or B and E-sharp, or F and C), and the black keys are shared between fingers 2, 3 and 4. A good habit is to learn those keys with the thumb positions first: find the white notes, put the thumb on them, and the rest of the fingering follows.

In F major the right hand uses the 4th finger on B-flat, the only black key in the scale, so that the thumb lands on C. In the flat keys from E-flat major to D-flat major the left hand starts on 3 and the thumb falls two or three notes later on a white key.

Melodic minor and descending

The melodic minor scale uses the raised sixth and seventh going up and the natural minor going down. This tool follows that: choose melodic minor and descending, and you get the natural minor notes with the reversed fingering. In C-sharp minor and F-sharp minor the raised sixth would put the thumb on a black key with the usual fingering, so the right hand switches to 3 4 1 2 3 4 1 2 going up.

Common questions

Why does fingering matter if I can reach the notes another way?

Consistent fingering lets you play a scale evenly and quickly because the hand always makes the same moves. It also builds the muscle memory that carries over to pieces: most runs in classical music use these exact patterns.

Which finger goes on the black keys?

Mostly fingers 2, 3 and 4. The thumb and the little finger are too short to reach the black keys comfortably, so the standard fingerings avoid them there. That is why every standard fingering in this tool keeps the thumb on white keys.

Is there more than one correct fingering?

A few scales have accepted alternatives. B-flat major in the right hand can start on 2 (2 1 2 3 1 2 3 4), and F-sharp minor in the right hand can use 2 3 1 2 3 1 2 3. Some teachers also prefer different fingerings for small hands. This tool shows the most widely taught fingering from the standard scale manuals. If your teacher uses another, follow your teacher.

How do I practise the thumb crossings?

Play slowly, hands separate, and keep the thumb moving under the hand early, as the previous finger plays. The wrist stays level and the hand does not rotate. Add a metronome once the crossing is silent and even, then increase the speed in small steps.
