Triad Diagrams — Sol Unresolved Cycle (Guitar)

Sol Unresolved CycleIV – V – I – vi

The G IV–V–I–vi (C – D – G – Em) creates forward momentum that never fully settles — the cycle loops back before the ear expects it. Use Mixolydian over the IV and V, then drop into the Minor Pentatonic as the vi chord arrives. The chord-scale approach to this rotation reveals how one key can imply four distinct modal centers. Extended voicings (CMaj7 – D7 – GMaj7 – Em7) amplify the hypnotic, unresolved quality.

Playing in Sol major

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 D (ascending whole step), D to G (ascending perfect fourth), G to E (descending minor third). 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 E to C by major 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 major pentatonic works because every note is either a chord tone or a safe passing tone — there are no avoid notes. For soloing, this means you can play freely without clashing. Over dominant seventh chords, G Mixolydian adds the flat seventh for an authentic blues-rock edge.

Strumming Pattern

Drive with all downstrokes at 140+ BPM for raw punk energy, or use D-D-DU-UDU for classic rock. Palm mute the verse and open up the strumming on the chorus for dynamic contrast.
