Sol Lydian II
I – II – IV – I progression in Sol major
Sol Lydian II — I – II – IV – I
The G Lydian II progression (G – A – C – G) uses a major II chord borrowed from the Lydian mode — a raised-4th harmonic lift that Lennon and McCartney used to make the familiar sound surprising. The Lydian scale and Lydian Pentatonic are the natural choices here, with Major Pentatonic grounding the I and IV chords. With seventh voicings (GMaj7 – AMaj7 – CMaj7 – GMaj7), the Lydian color becomes luminous and floating.
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 G to A (ascending whole step), A to C (ascending minor third), C to G (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 G to G by unison.
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.
