The G Harmonic Minor scale is a variation of the minor scale that introduces a strong leading tone. On Guitar, the notes are G, A, Bb, C, D, Eb, F#. It has a distinctive exotic or Middle Eastern flavor due to the wide gap between its upper notes, and is used to provide the harmonic tension necessary for classical minor-key resolutions. It is a staple in neo-classical metal and flamenco. The diatonic chords of G Harmonic Minor are GmMaj7, Am7b5, Bb+maj7, Cm7, D7, Ebmaj7, F#o7. Commonly used in Metal, Classical, Flamenco, Film Scores, Neoclassical. Notable players include Yngwie Malmsteen, Ritchie Blackmore, Johann Sebastian Bach. Use over m(Maj7), m7, dim7 chords. Essential for creating V7 → i resolutions in minor keys. The raised 7th provides the leading tone that natural minor lacks.

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
