Practice notes for the A major scale

A major has three sharps, C♯, F♯ and G♯: A B C♯ D E F♯ G♯ A. The right hand uses the same fingering as C, G and D major, so the work here is the black keys, not new finger numbers.

Where it goes wrong. G♯. It is the third black key in a row in the upper half of the scale, and it is easy to play G instead, or to play it short because the hand is rushing to the top A. In the left hand the trouble spot is lower: finger 3 crosses over to F♯, and that crossing lands on a black key.

How to practice it. Play the upper half alone, E F♯ G♯ A, with fingers 2 3 4 5. The two black keys sit together under 3 and 4. Then the lower half, A B C♯ D, with 1 2 3 and the thumb under to D. Join them at a slow, even beat, hands separately, and only then together.

What to listen for. G♯ to A, the half step back to the keynote. Play the scale and stop on G♯: it should sound unfinished. If it does not, check that you played G♯ and not G.

What to learn next. E major, which adds D♯, and F♯ minor, the relative minor of A major, with the same three sharps.
