Si Ascending Augmented
I – I+ – I6 – I7 progression in Si major
Si Ascending Augmented — I – I+ – I6 – I7
The B Ascending Augmented progression (B – Baug – B6 – B7) 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 (BMaj7 – Baug – B6 – B7), the chromatic ascent gains full harmonic richness.
Playing in Si major
B major mixes barre and open elements. The B chord itself is a barre at fret 2, but E and A are comfortable open chords forming the IV and V. The open B string rings as the root, allowing creative drone-based arrangements. B is a intermediate-level key on guitar because the open B string rings as the root and the open E strings provide the 4th — useful for sus4 voicings and drone effects. This key mixes open and barre shapes, making it a good intermediate challenge that builds fretboard fluency.
Voice Leading
The bass line moves through B to B (ascending unison), B to B (ascending unison), B to B (ascending unison). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from B to B by unison.
Capo Transposition
To play in B using familiar open chords: capo 2 with open A shapes; capo 4 with open G shapes; capo 7 with open E 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
B 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, B 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.
