Progressions in B — Mandocello

Every chord the key of B owns, as CGDA shapes ready to back a tune.

B major harmonizes to B – C#m – D#m – E – F# – G#m – A#°; B minor to Bm – C#° – D – Em – F#m – G – A. Each chord links to its Mandocello shapes, so backing a tune in B starts here and ends under your fingers.

Run the changes that carry the repertoire — I–IV–V for the dance tunes, i–VII–VI where the airs go modal — until moving between shapes stops costing thought.
