Please explain this so I can understand it?
Thanks in advance.
The whole tone scale is a scale composed entirely of notes that are 1 whole step apart. There are only 2 of them:
C, D, E/Fb, F#/Gb, G#/Ab, A#/Bb (then it repeats)
C#/Db, D#/Eb, E#/F, G, A, B/Cb (then it repeats)
You hear this scale in movies or plays where someone is having a dream or walking up an endless flight of stairs or something of that nature.
