Progressions in D# — Mandocello
Every chord the key of D# owns, as CGDA shapes ready to back a tune.
D# major harmonizes to D# – Fm – Gm – G# – A# – Cm – D°; D# minor to D#m – F° – F# – G#m – A#m – B – C#. Each chord links to its Mandocello shapes, so backing a tune in D# 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.
