It combines the stability of a major sound with a more relaxed, folk-like ending, perfectly suited for soloing over dominant seventh chords and providing a bluesy, soulful vibe to major-key songs. The diatonic chords of A Mixolydian are A7, Bm7, C#m7b5, DMaj7, Em7, F#m7, GMaj7. Commonly used in Blues, Rock, Country, Folk, Funk. Notable players include Jimi Hendrix, The Allman Brothers, AC/DC, Stevie Ray Vaughan. Use over dominant 7th chords (7, 9, 13). The primary scale for blues-rock soloing over non-resolving dominant chords.

About Open C Tuning
Open C tuning (C-G-C-G-C-E) produces a C major chord when strummed open, with an enormous bass depth from the low C string (two whole steps below standard E). The tuning spans a vast tonal range that gives compositions an almost orchestral scope, making it a favorite for both delicate fingerstyle and crushing heavy music.
John Butler's 'Ocean' — one of the most famous modern fingerstyle compositions — is performed in Open C, showcasing the tuning's incredible dynamic range from thundering bass to shimmering harmonics. Devin Townsend uses Open C extensively across his catalog for its massive, wall-of-sound potential. Jimmy Page used it on Led Zeppelin's 'Friends' from Led Zeppelin III. Soundgarden also explored Open C. The three C strings and two G strings create powerful octave resonances that make even simple chord shapes sound huge.
Notable artists: John Butler, Devin Townsend, Jimmy Page (Led Zeppelin), Soundgarden, William Ackerman
Best for: Cinematic fingerstyle compositions, progressive metal walls of sound, post-rock textures, and any music that needs enormous tonal range from deep bass to bright treble
Musical Character
The b7 softens the major scale's resolution, creating a 'relaxed major' that never quite lands. This is the sound of rock and roll — major but with attitude.
