Sol Ascending Augmented
I – I+ – I6 – I7 progression in Sol major
Sol Ascending Augmented — I – I+ – I6 – I7
The G Ascending Augmented progression (G – Gaug – G6 – G7) is a line-cliché technique: the bass holds the tonic while an inner voice climbs I–aug–vi, creating yearning tension that demands resolution. The Whole Tone scale fits the augmented chord precisely; Major and Mixolydian cover the surrounding diatonic chords. Augmented harmony appears in both jazz ballads and classic pop introductions for good reason. With seventh voicings (GMaj7 – Gaug – G6 – G7), the chromatic ascent gains full harmonic richness.
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 G (ascending unison), G to G (ascending unison), G to G (ascending unison). The predominantly stepwise bass motion creates smooth, connected voice leading. 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
Use D-DU-UDU at 100-120 BPM for a standard pop strum. Accent beats 2 and 4 for a backbeat feel. Vary dynamics between verse (lighter) and chorus (stronger) to build energy.
