Autumn In New York in A#
This bittersweet ballad supports Dorian phrasing on the minor sections, Mixolydian color on the bluesy dominants, and Bebop Major lines on the major tonic resolutions. The shifting tonal moods mirror the song's emotional ambivalence between nostalgia and longing. Tasteful dynamic shaping and a singing tone are essential to conveying the tune's urban melancholy.
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 C to D (ascending whole step), D to D# (ascending half step), D# to F (ascending whole step), F to A# (ascending perfect fourth), A# to G (descending minor third), G to D (descending perfect fourth), D to G (ascending perfect fourth), G to D# (descending major third), D# to G# (ascending perfect fourth), G# to C# (ascending perfect fourth), C# to G (ascending tritone), G to F (descending whole step), F to G (ascending whole step), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to F (ascending unison), F to F# (ascending half step), F# to G# (ascending whole step), G# to A# (ascending whole step), A# to D# (ascending perfect fourth), D# to C# (descending whole step), C# to B (descending whole step), B to A# (descending half step), A# to A# (ascending unison), A# to C# (ascending minor third), C# to F# (ascending perfect fourth), F# to F (descending half step). A half-step bass movement creates a strong leading-tone pull that demands resolution. The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from F 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.
