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.
