How many notes are there in a gamelan scale?

The Diatonic scale (most commonly knows as the Major Scale) has 7 unique pitches. For example: C D E F G A B would be considered the notes of the C Major scale. Although traditionally the C would repeat again on top, it is to a NEW note, but simply the repeating of the first (root) note.

The chromatic scale contains 12 notes, and it is most easily explained as every note on the piano within an Octave.

C C# D D# E F F# G G# A A# B

The Diminished Scale contains 8 notes Example: C C# D# E F# G A Bb

And the Whole Tone Scale contains 6 notes Example: C D E F# G# A#
