Si Minor Blues
i – iv – i – V progression in Si minor
Si Minor Blues — i – iv – i – V
The B minor blues (Bm – Em – Bm – F#) concentrates the darkest emotional territory of the blues form. Minor Pentatonic and the Dorian mode fit the i and iv chords; Phrygian Dominant or Harmonic Minor adds tension over the V chord's dramatic arrival. The Harmonic Minor scale is essential here — its raised 7th creates the authentic minor blues resolution. With seventh voicings (Bm7 – Em7 – Bm7 – F#7), the depth is uncompromising.
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 E (ascending perfect fourth), E to B (descending perfect fourth), B to F# (descending perfect fourth). 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 F# to B 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
Use a shuffle pattern: D-u-D-u with swung eighth notes at 80-120 BPM. The triplet feel is essential — think of each beat divided into three, skipping the middle note. Add palm muting on the bass strings for a tighter groove.
