G Lydian Scale — Notes and Intervals
The G Lydian scale is the fourth mode of the major scale and arguably the brightest sound in music theory. On Bass, the notes are G, A, B, C#, D, E, F#. It is known for its ethereal, dreamlike, and cinematic quality. Because it avoids the pull of the perfect fourth, it is a favorite for film composers wanting to evoke a sense of wonder or otherworldly space. The diatonic chords of G Lydian are GMaj7, A7, Bm7, C#m7b5, DMaj7, Em7, F#m7. Commonly used in Film Scores, Progressive Rock, Fusion, Ambient, Dream Pop. Notable players include Joe Satriani, Steve Vai, John Williams, Hans Zimmer. Use over Maj7#11, Maj9 chords. Ideal for non-resolving major passages. Avoid when the music needs to feel grounded or resolved.

How to Play G Lydian 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 Lydian scale contains 2 sharps (C#, F#). Its relative minor is E minor, which shares the same notes.
Practice Routine
Begin by playing the G Lydian scale ascending and descending at 80 BPM using a metronome, one note per beat. Once comfortable, practice in thirds (G-B, A-C#) to build intervallic familiarity. Spend 5 minutes daily on this pattern before increasing tempo by 10 BPM.
Try these progressions with the G Lydian scale: GMaj7 - C#m7b5 - DMaj7 - GMaj7 (I-IV-V-I) or GMaj7 - A7 - C#m7b5 - DMaj7 for a more stepwise movement.
Bass Tips

The G Lydian scale contains 7 notes (G, A, B, C#, D, E, F#). Use the interactive fretboard above to explore this scale on Bass with different tunings and fret ranges.
CAGED Positions & Patterns for G Lydian
The G Lydian 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.
