A# Whole Tone Scale — Notes and Intervals
The A# Whole Tone scale, also known as Messiaen's Mode of Limited Transposition #1, is a perfectly symmetrical scale that lacks a tonal center, creating a sense of weightlessness and blur. On Piano, it contains the notes A#, C, D, E, E##, F###. It divides the octave into six equal whole steps, meaning only two unique whole tone scales exist. Popularized by Claude Debussy and used extensively in film scores, it evokes impressionistic, dreamlike atmospheres where no single note feels like home. Use it over augmented triads and 7#5 chords for a floating, surreal effect. Commonly used in Impressionist, Film Scores, Jazz, Ambient, Experimental. Notable players include Claude Debussy, Thelonious Monk, Wayne Shorter, Joe Satriani. Use over augmented triads, 7#5 chords. Perfect for dream sequences, transitions, and any moment where tonality should dissolve.
