The Whole Tone Scale uses every other note on the keyboard. Again, when the notes ascend sharps (#) are used. When the notes descend flats (b) are used. The Whole Tone Scale also lacks a Tonic or Tonal Center, and creates an ambiguous almost mystical sound. Technically there are two (2) Whole Tone Scales. The One shown below starting on "C", and a second one that starts on "C#". The Whole Tone Scale consists of only Whole Steps. There are NO Half Steps in the Whole Tone Scale.
