Evidence in La

Monk's angular bebop composition — built on the "Just You, Just Me" changes — deploys Bebop Major, Mixolydian, and Dorian language through a distinctly personal A lens. The rhythmic displacement and melodic chromaticism challenge conventional bebop phrasing patterns. The AMaj7 – F#m7 – Bm7 – E7 – D7 – G7 – C7 changes sharpen a soloist's sense of metric flexibility and harmonic surprise.

Evidence in La

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 A to F# (descending minor third), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to D (descending whole step), D to G (ascending perfect fourth), G to C (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 C to A by minor third.

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.
