G Phrygian Major Scale — Notes and Intervals
The G Phrygian Major scale is a palindromic mode whose interval sequence reads identically forwards and backwards, with its lower half drawn from Phrygian and its upper half from Ionian. On Bass, it contains the notes G, Ab, Bb, C, D, E, F#. This non-invertible symmetry allows melodies that carry equal weight ascending and descending, making it a tool for experimental and contemporary classical composition. Commonly used in Experimental, Contemporary Classical, Ambient. Notable players include Gyorgy Ligeti, Bela Bartok. Use over sustained chords and pedal tones in experimental contexts. The symmetric structure allows melodic passages that sound equally natural ascending and descending.
Notes: G, Ab, Bb, C, D, E, F#
Intervals: 1P, 2m, 3m, 4P, 5P, 6M, 7M
Degrees: 1 b2 b3 4 5 6 7
Formula: H-W-W-W-W-W-H
Number of notes: 7
Musical Character
A non-invertible (palindromic) mode: its interval sequence reads the same forwards and backwards (1-2-2-2-2-2-1). The lower half is Phrygian while the upper half is Ionian, creating a scale that transforms character as it ascends.

How to Use the G Phrygian Major Scale
Use over sustained chords and pedal tones in experimental contexts. The symmetric structure allows melodic passages that sound equally natural ascending and descending.
Origin & Background
A synthetic mode notable for its palindromic interval structure. It belongs to the small family of non-invertible modes whose transposition pattern is symmetric. Useful in composition where ascending and descending motion should carry equal weight.
How to Play G Phrygian Major on Bass
On bass, locate G on the E string at fret 3. 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 G Phrygian Major scale contains both sharps and flats (1 sharp, 2 flats), which is common in altered and exotic scales. Its relative major is Bb major, which shares the same key signature.
Practice Routine — Exercises for Playing
Set a metronome to 100 BPM and play the G Phrygian Major 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 G to let the characteristic intervals of the Phrygian Major scale come through clearly. This scale is especially effective in contemporary classical contexts.
Bass Tips
On bass, use the G Phrygian Major scale to build walking bass lines by targeting chord tones on strong beats and using scale tones as approach notes. This is the foundation of functional bass playing. Aim for a balanced quality in your phrasing to match the natural character of this scale.

CAGED Positions & Patterns for G Phrygian Major
The G Phrygian Major scale can be played in 5 CAGED positions across the fretboard, each based on an open chord shape (C, A, G, E, D). As a 7-note scale, it also lends itself to 3-notes-per-string (3NPS) patterns that facilitate legato playing and diagonal shifting. Use the pattern selector above to isolate each position.
