Lullaby Of Birdland in A#
Lullaby of Birdland in A#: George Shearing's minor standard spins its melody over Dorian and Aeolian harmony with chromatic V7♭9 dominant tension. Harmonic Minor resolves the dominant chords — the swing feel is buoyant despite the minor mode. Chords: A#m6 – Gm7b5 – C7b9 – F7b9 – A#m7 – F#Maj7 – D#m7 – G#7 – Fm7 – G#7b9 – C#Maj7 – F#9 – Cm7b5 – F7 – G#9 – C# – Fm7b5 – A#7b9 – DMaj7 – C#maj9.
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 G (descending minor third), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to A# (ascending perfect fourth), A# to F# (descending major third), F# to D# (descending minor third), D# to G# (ascending perfect fourth), G# to F (descending minor third), F to G# (ascending minor third), G# to C# (ascending perfect fourth), C# to F# (ascending perfect fourth), F# to C (ascending tritone), C to F (ascending perfect fourth), F to G# (ascending minor third), G# to C# (ascending perfect fourth), C# to F (ascending major third), F to A# (ascending perfect fourth), A# to D (ascending major third), D to C# (descending half step). 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 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.
