Sol Flamenco Modulation
iv – III/II – III⁺ – II⁺ – I⁺ progression in Sol minor
Sol 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 Sol minor
G major is the singer-songwriter's key. The open G, B, and D strings spell out the full G major triad with zero fretting. Add the open high E for a Gadd6 shimmer. Nearly every diatonic chord (Em, Am, C, D) has a comfortable open voicing. G is a beginner-level key on guitar because the open G, B, and D strings form a complete G major triad without fretting a single note, and the open low E adds a rich 6th color. Beginners will find this key approachable since most chords use open voicings with minimal stretching.
Voice Leading
The bass line moves through C to Bb (descending whole step), Bb to B (ascending half step), B to Bb (descending half step), Bb to A (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 A to C by minor third.
Capo Transposition
To play in G using familiar open chords: capo 3 with open E shapes; capo 5 with open D shapes; capo 7 with open C 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
G 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 G 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.
