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: A#m7 – F#7/c – A#m6 – F#9/c – A#m9 – Gm7b5 – C#13 – F#Maj7 – F7b5 – Cm11 – C7b9 – F#9 – F7b9 – A#m – Cm7 – F7 – F7#5 – A#m/Bb – A#mMaj7 – G#m9 – C#7b9 – F#maj9 – D#7b9 – Bmaj9 – Gm9 – FMaj7 – A#maj9 – Bm7 – E7#5.
Key of A#
A# (Bb) major requires barre chords rooted at fret 1 on the A string or fret 6 on the E string. Despite the barre demands, it is a common key in funk, New Orleans R&B, and brass band music. The open D string can ring as the major third for added color. A# is a intermediate-level key on guitar because the open D string is the major 3rd of Bb, adding a bright color if allowed to ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.
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 G (descending minor third), G to C# (ascending tritone), C# to F# (ascending perfect fourth), F# to F (descending half step), F to C (descending perfect fourth), C to C (ascending unison), C to F# (ascending tritone), F# to F (descending half step), F to A# (ascending perfect fourth), A# to C (ascending whole step), C to F (ascending perfect fourth), F to F (ascending unison), F 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 B (descending major third), B to G (descending major third), G to F (descending whole step), F to A# (ascending perfect fourth), A# to B (ascending half step), B to E (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 E 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.
