Do Ascending Augmented
I – I+ – I6 – I7 progression in Do major
Do Ascending Augmented — I – I+ – I6 – I7
The C Ascending Augmented progression (C – Caug – C6 – C7) 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 (CMaj7 – Caug – C6 – C7), the chromatic ascent gains full harmonic richness.
Playing in Do major
With no sharps or flats, C major is the theoretical home base on guitar. The open G, B, and high E strings all belong to the C major chord, creating natural sustain. C is a beginner-level key on guitar because the open B and high E strings ring within the scale, and every basic chord uses familiar open shapes. Beginners will find this key approachable since most chords use open voicings with minimal stretching.
Voice Leading
The bass line moves through C to C (ascending unison), C to C (ascending unison), C to C (ascending unison). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from C to C by unison.
Capo Transposition
To play in C using familiar open chords: capo 3 with open A shapes; capo 5 with open G 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
C 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, C 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.
