La# Alegrías — I – V7 – I – IV – I – V7 – I
Joyful flamenco palo from Cadiz in major mode. Unlike most flamenco which uses the Phrygian mode, Alegrias lives in pure major tonality (typically E major). The 12-beat ternary cycle with accents on 3, 6, 8, 10, 12 shares the solea family rhythmic structure but with a bright, celebratory character.
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 F (descending perfect fourth), F to A# (ascending perfect fourth), A# to D# (ascending perfect fourth), D# to A# (descending perfect fourth), A# to F (descending perfect fourth), F to A# (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 A# to A# by unison.
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
Try a D-D-DU waltz pattern at 80-100 BPM. Accent beat 1 strongly and keep beats 2-3 lighter. For fingerpicking, use a bass-pluck-pluck pattern with alternating bass notes.
