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 A Harmonic Minor are AmMaj7, Bm7b5, C+maj7, Dm7, E7, Fmaj7, G#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.

About 8-string Tuning
The 8-string guitar adds both a low B and a low F# string (F#-B-E-A-D-G-B-E), pushing the instrument's range almost into bass guitar territory. This massive tonal range has become the weapon of choice for djent, progressive metal, and experimental composers who need bone-crushing low-end and soaring highs in a single instrument.
With artists like Tosin Abasi, Meshuggah, and After the Burial leading the charge, the 8-string guitar has redefined what's possible in modern heavy music. The low F# string delivers subsonic heaviness that you can feel in your chest, while the upper strings maintain standard guitar voicings for leads and clean passages. Extended-range compositions often exploit the full span of the instrument, creating a wall of sound that covers bass, rhythm, and lead guitar roles simultaneously.
Notable artists: Meshuggah, Animals as Leaders, After the Burial, Intervals, Monuments
Best for: Djent polyrhythms, extended-range metal riffs, experimental compositions, and one-instrument arrangements spanning bass to lead
