A# Mystery #1 Scale — Notes and Intervals
The A# Mystery #1 scale is a rare and experimental synthetic scale found in modern music theory. On Bass, its notes are A#, B, D, E, F#, G#. It is typically associated with generative music and computer-aided composition where traditional rules of melody and harmony are intentionally broken. Commonly used in Experimental, Computer Music, Avant-Garde. Used in experimental, non-functional contexts. A compositional curiosity for exploring unconventional melodic paths.
Notes: A#, B, D, E, F#, G#
Intervals: 1P, 2m, 3M, 5d, 6m, 7m
Degrees: 1 b2 3 4 b5 b6
Formula: H-WH-W-W-W-W

How to Play A# Mystery #1 on Bass
On bass, locate A# on the A string at fret 1. Use a one-finger-per-fret approach starting from the root and span two to three strings. Keep your fretting hand relaxed and practice shifting between positions cleanly.
The A# Mystery #1 scale contains 3 sharps (A#, F#, G#). 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# Mystery #1 scale ascending and descending at 80 BPM using a metronome, one note per beat. Once comfortable, practice in thirds (A#-D, B-E) 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 Mystery #1 scale come through clearly.
Bass Tips
Practice the A# Mystery #1 scale on bass using only your index and ring fingers for a two-finger-per-string approach, then switch to one-finger-per-fret. Both techniques are essential for different musical situations.
The A# Mystery #1 scale contains 6 notes (A#, B, D, E, F#, G#). Use the interactive fretboard above to explore this scale on Bass with different tunings and fret ranges.
CAGED Positions & Patterns for A# Mystery #1
