Sol Minor Blues
i – iv – i – V progression in Sol minor
Sol Minor Blues — i – iv – i – V
The G minor blues (Gm – Cm – Gm – D) 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 (Gm7 – Cm7 – Gm7 – D7), the depth is uncompromising.
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 G to C (ascending perfect fourth), C to G (descending perfect fourth), G to D (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 D to G by perfect fourth.
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
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.
