Angel Eyes in A
Angel Eyes in A — a dark, brooding ballad with sustained minor tension. Dorian suits the extended minor vamp; Harmonic Minor tightens the cadential moments; blues inflections add emotional weight. Changes: Am7 – F7/c – Am6 – F9/c – Am9 – F#m7b5 – C13 – FMaj7 – E7b5 – Bm11 – B7b9 – F9 – E7b9 – Am – Bm7 – E7 – E7#5 – Am/Bb – AmMaj7 – Gm9 – C7b9 – Fmaj9 – D7b9 – A#maj9 – F#m9 – EMaj7 – Amaj9 – A#m7 – D#7#5.
Key of A
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 major third), F to A (ascending major third), A to F (descending major third), F to A (ascending major third), A to F# (descending minor third), F# to C (ascending tritone), C to F (ascending perfect fourth), F to E (descending half step), E to B (descending perfect fourth), B to B (ascending unison), B to F (ascending tritone), F to E (descending half step), E to A (ascending perfect fourth), A to B (ascending whole step), B to E (ascending perfect fourth), E to E (ascending unison), E to A (ascending perfect fourth), A to A (ascending unison), A to G (descending whole step), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to D (descending minor third), D to A# (descending major third), A# to F# (descending major third), F# to E (descending whole step), E to A (ascending perfect fourth), A to A# (ascending half step), A# to D# (ascending perfect fourth). A half-step bass movement creates a strong leading-tone pull that demands resolution. 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 D# to A by tritone.
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.
