Major scales explained on a virtual piano

Definition of major scales

A major scale is a sequence of eight notes such that:
  • the 2nd note is 2 semitones above the 1st
  • the 3rd note is 2 semitones above the 2nd
  • the 4th note is 1 semitone above the 3rd
  • the 5th note is 2 semitones above the 4th
  • the 6th note is 2 semitones above the 5th
  • the 7th note is 2 semitones above the 6th
  • the 8th note is 1 semitone above the 7th
The pattern is 0+2+2+1+2+2+2+1 = 12 (an octave).
Alternatively, a major scale is a sequence of eight notes such that:
  • the 2nd note is 2 semitones above the first
  • the 3rd note is 4 semitones above the first
  • the 4th note is 5 semitones above the first
  • the 5th note is 7 semitones above the first
  • the 6th note is 9 semitones above the first
  • the 7th note is 11 semitones above the first
  • the 8th note is 12 semitones above the first
The pattern is [0, 2, 4, 5, 7, 9, 11, 12].

Uniformly spaced piano keys play major scales

These buttons play major scales. They are arranged uniformly so that there is no difference between white and black keys. This helps to understand the mathematical regularity of the scales, which is hard to see because of the way the black keys are tucked between the white keys.
