La# Jazz Turnaround
I – vi – ii – V progression in La# major
La# Jazz Turnaround — I – vi – ii – V
The A# I–vi–ii–V turnaround (A# – Gm – Cm – F) moves through the circle of fourths — a harmonic engine that links jazz, doo-wop, and early rock. Dorian mode fits over the ii chord while Mixolydian handles the V; the Bebop Major scale threads chromatic passing tones over the I. With seventh voicings (A#Maj7 – Gm7 – Cm7 – F7), this becomes the standard jazz rhythm-changes turnaround.
Playing in La# major
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). 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 F to A# by perfect fourth.
Capo Transposition
To play in A# using familiar open chords: capo 1 with open A shapes; capo 3 with open G shapes; capo 6 with open E shapes. Choose the capo position that gives you the voicings you prefer — lower capo positions produce a fuller sound, while higher positions create a brighter, mandolin-like timbre.
Scales for Soloing
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.
Strumming Pattern
Use Freddie Green-style comping: short, muted chord stabs on beats 2 and 4 at 120-160 BPM. Keep the chords tight and percussive, lifting your fretting hand slightly after each attack to control sustain.
