The Logic of Scales

Explore scales with colors, numbers and piano keyboard.
Examples on this page will be with the key of C.
Root/key note, where the scale starts, is "1" or Red.
Remember, colors and numbers are always relative!

The Chromatic Scale

is the canvas with all the musical pitches/notes, 12 per octave.
Neighboring notes are 1 semitone (pitch interval) apart.
All other scale types will be extracted from it.

Major / Minor

Let's look how major and minor scales are built from the chromatic scale.
Notice that the pitch intervals are having a pattern.
They have 7 notes per octave.

C Major Scale

7 notes per octave with pitch intervals having a pattern:
2, 2, 1, 2, 2, 2, 1 semitones apart (starting from the root).

C Minor Scale

7 notes per octave with pitch intervals having a pattern:
2, 1, 2, 2, 1, 2, 2 semitones apart (starting from the root).

C Major Pentatonic

Major pentatonic scale is extracted from the major scale.
5 notes per octave with pitch intervals having a pattern:
2, 2, 3, 2, 3 semitones apart (starting from the root).

C Minor Pentatonic

Minor pentatonic scale is extracted from the minor scale.
5 notes per octave with pitch intervals having a pattern:
3, 2, 2, 3, 2 semitones apart (starting from the root).
