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 Cavaquinho, 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.

How to Play A# Whole Tone on Cavaquinho
Begin by locating A# on your instrument and play through the 6 notes of the Whole Tone scale slowly, ensuring each note rings clearly before increasing speed.
The A# Whole Tone scale contains 3 sharps (A#, E##, F###). This scale does not follow a traditional major or minor key signature, so reading from sheet music may require accidentals.
Practice Routine
Set a metronome to 80 BPM and play the A# Whole Tone scale in groups of four notes, shifting the starting note each repetition. This builds muscle memory across the entire scale range. After a week, try improvising short 4-bar phrases using only these notes.
Experiment with simple two-chord vamps rooted on A# to let the characteristic intervals of the Whole Tone scale come through clearly. This scale is especially effective in impressionist contexts.
Cavaquinho Tips
Practice the A# Whole Tone scale slowly and evenly on your instrument, focusing on tone quality for each of the 6 notes before building speed. Aim for a weightless quality in your phrasing to match the natural character of this scale.
