Hot House in La

Dizzy Gillespie's bebop contrafact over "What Is This Thing Called Love" adds Bebop Major vocabulary and Harmonic Minor tension to a A foundation. Locrian color appears at pivotal moments, testing a soloist's command of altered and diminished harmonic space. The Em7b5 – A7b9 – Dm – Bm7b5 – E7b9 – AMaj7 – Bm7 – E7 changes are a bebop rite of passage that separates the fluent improviser from the merely competent.

A major is a rock and blues cornerstone. The open A string delivers a strong root, while both E strings ring as the fifth. Classic A-D-E progressions practically play themselves with open cowboy chords. The open high E is the fifth, reinforcing power. A is a beginner-level key on guitar because the open A string is the root and the open E strings provide the fifth above and below, creating a massive low-end anchor. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through E to A (ascending perfect fourth), A to D (ascending perfect fourth), D to B (descending minor third), B to E (ascending perfect fourth), E to A (ascending perfect fourth), A to B (ascending whole step), B to E (ascending perfect fourth). The root motion by larger intervals (fourths and fifths) gives each chord change a strong, decisive character. When the progression loops, the bass returns from E to E by unison.

Scales for Improvisation

A major pentatonic works because every note is either a chord tone or a safe passing tone — there are no avoid notes. For soloing, this means you can play freely without clashing. Over dominant seventh chords, A Mixolydian adds the flat seventh for an authentic blues-rock edge.
