Si Soleá with Substitutions
iv – VI – V – I progression in Si minor
Si Soleá with Substitutions — iv – VI – V – I
Variant of the Andalusian cadence where the intermediate III is replaced by the secondary VI chord, and the resolutive II is replaced by the diminished V. This substitution system (Granados) generates dozens of cadencia variants by mixing principal (IV-III-II-I) and secondary (VII-VI-V) chords.
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 E to G (ascending minor third), G to F# (descending half step), F# to B (ascending perfect fourth). A half-step bass movement creates a strong leading-tone pull that demands resolution. 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 B to E by perfect fourth.
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.
