Si Bulerías
I – II – I progression in Si minor
Si Bulerías — I – II – I
The fastest and most virtuosic palo of flamenco. Uses the same 12-beat cycle as Solea but at much higher tempo. The minimal I-II-I structure is the core harmonic cell of Bulerias 'al 1'. Can be expanded to I-II-III-II-I or I-II-III-VII-I. In A Phrygian: A-Bb-A.
Playing in Si minor
B major mixes barre and open elements. The B chord itself is a barre at fret 2, but E and A are comfortable open chords forming the IV and V. The open B string rings as the root, allowing creative drone-based arrangements. B is a intermediate-level key on guitar because the open B string rings as the root and the open E strings provide the 4th — useful for sus4 voicings and drone effects. This key mixes open and barre shapes, making it a good intermediate challenge that builds fretboard fluency.
Voice Leading
The bass line moves through B to C (ascending 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 B by unison.
Capo Transposition
To play in B using familiar open chords: capo 2 with open A shapes; capo 4 with open G shapes; capo 7 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
B 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 B 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.
