Musical scales

A scale is a set of eight notes going from one note to the same note an octave higher.

Major scales

All major scales use the same pattern of steps:
Whole, Whole, Half, Whole, Whole, Whole, Half

Notes in a major scale are named by scale degree:

  1. Tonic
  2. Supertonic
  3. Mediant
  4. Subdominant
  5. Dominant
  6. Submediant
  7. Leading tone
  8. Tonic

Minor scales

There are three minor forms:

Natural minor

Pattern: Whole, Half, Whole, Whole, Half, Whole, Whole

Harmonic minor

Same as natural minor but with a raised seventh.

Melodic minor

  • Ascending: raised sixth and seventh.
  • Descending: natural minor form.

Chromatic scale

A chromatic scale uses every semitone in the octave.

  • Ionian – major scale
