Si Ragtime Cycle
I – VI7 – II7 – V progression in Si major
Si Ragtime Cycle — I – VI7 – II7 – V
The B Ragtime Cycle (B – G# – C# – F#) converts the vi and ii into secondary dominant 7th chords, driving relentlessly through the circle of fifths. Mixolydian Pentatonic outlines each dominant chord cleanly; the Bebop scale adds chromatic passing tones for authentic ragtime and early jazz phrasing. Mixolydian mode fills out the full chord-scale vocabulary. With seventh voicings (BMaj7 – G#7 – C#7 – F#7), the forward cycle-of-fifths motion becomes irresistible.
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 G# (descending minor third), G# to C# (ascending perfect fourth), C# to F# (ascending 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 F# to B by perfect fourth.
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 Freddie Green-style comping: short, muted chord stabs on beats 2 and 4 at 120-160 BPM. Keep the chords tight and percussive, lifting your fretting hand slightly after each attack to control sustain.
