The A Harmonic Minor scale is a variation of the minor scale that introduces a strong leading tone. On Bass, the notes are A, B, C, D, E, F, G#. 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. Essential for creating V7 → i resolutions in minor keys. The raised 7th provides the leading tone that natural minor lacks.

CAGED Positions & Patterns for A Harmonic Minor
The A Harmonic Minor 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.
