La# Flamenco Modulation
iv – III/II – III⁺ – II⁺ – I⁺ progression in La# minor
La# Flamenco Modulation — iv – III/II – III⁺ – II⁺ – I⁺
Modulation between Phrygian modes. The III chord of one mode becomes the II (Resolutive) of a new mode one semitone higher, creating a dramatic key shift. Granados documents this as 'Direct Modulation': E mode → F# mode via G (III of E = II of F#). Essential for concert flamenco guitar.
Playing in La# minor
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 Eb to Db (descending whole step), Db to D (ascending half step), D to Db (descending half step), Db to C (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 C to Eb by minor third.
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# minor pentatonic is your safest starting point because all five notes are chord tones or stable tensions within the natural minor harmony. When a dominant seventh chord appears, switch briefly to A# Dorian or harmonic minor to capture the raised 6th or 7th that the chord implies.
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.
