A Six Tone Symmetric Scale — Notes and Intervals
The A Six Tone Symmetric scale is a mathematical abstraction that divides the octave into six equal parts. On Ukulele, its notes are A, Bb, C#, D, F, F#. It lacks a tonic or a home note, making it perfect for modern composers who want to avoid traditional keys and explore total tonal suspension. Commonly used in Contemporary Classical, Experimental, Avant-Garde. Notable players include Bela Bartok, Olivier Messiaen. Use for atonal or polytonal composition. Not chord-specific — this is a tool for breaking free of traditional harmony.
Notes: A, Bb, C#, D, F, F#
Intervals: 1P, 2m, 3M, 4P, 5A, 6M
Degrees: 1 b2 3 4 #5 6

How to Play A Six Tone Symmetric on Ukulele
On ukulele, find A on the open strings or work through the scale within a four-fret span. You may need to shift positions once to cover all 6 notes. Practice each position separately before linking them together.
The A Six Tone Symmetric scale contains both sharps and flats (2 sharps, 1 flat), which is common in altered and exotic scales. This scale does not follow a traditional major or minor key signature, so reading from sheet music may require accidentals.
Practice Routine
Begin by playing the A Six Tone Symmetric scale ascending and descending at 80 BPM using a metronome, one note per beat. Once comfortable, practice in thirds (A-C#, Bb-D) to build intervallic familiarity. Spend 5 minutes daily on this pattern before increasing tempo by 10 BPM.
Experiment with simple two-chord vamps rooted on A to let the characteristic intervals of the Six Tone Symmetric scale come through clearly.
Ukulele Tips
