Once I Loved in 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 C to F (ascending perfect fourth), F to A# (ascending perfect fourth), A# to B (ascending half step), B to C# (ascending whole step), C# to D (ascending half step), D to D (ascending unison), D to A# (descending major third), A# to D# (ascending perfect fourth), D# to G# (ascending perfect fourth), G# to A (ascending half step), A to D (ascending perfect fourth), D to G (ascending perfect fourth), G to G (ascending unison), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to A# (ascending perfect fourth), A# to D# (ascending perfect fourth), D# to E (ascending half step), E to D# (descending half step), D# to D (descending half step), D to C# (descending half step), C# to G (ascending tritone), G to G (ascending unison). 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 G to C by perfect fourth.

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.
