From one note to the next, the scale moves like this: T – T – S – T – T – T – S (T = whole step, S = half step). That pattern is the same in every key: once you learn it, you can build the major scale from any note.

How to practice this scale
- Play it slowly with a metronome, one note per beat, and only speed up once it sounds even.
- Sing the note names while you play it: that way you train your ear and your memory at the same time.
- On piano, use the fingering from your teacher or a method book: in most scales the thumb passes under after the third finger.
- Also practice the scale's triads (the chords below) to understand how the harmony of songs is built.
