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 major is a rock and blues cornerstone. The open A string delivers a strong root, while both E strings ring as the fifth. Classic A-D-E progressions practically play themselves with open cowboy chords. The open high E is the fifth, reinforcing power. A is a beginner-level key on guitar because the open A string is the root and the open E strings provide the fifth above and below, creating a massive low-end anchor. Beginners will find this key approachable since most chords use open voicings with minimal stretching.
Voice Leading
The bass line moves through D to C (descending whole step), C to Db (ascending half step), Db to C (descending half step), C to B (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 B to D by minor third.
Capo Transposition
To play in A using familiar open chords: capo 2 with open G shapes; capo 5 with open E shapes; capo 7 with open D 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.
