Progressions in C# — Octave Mandolin

Every chord the key of C# owns, as GDAE shapes ready to back a tune.

C# major harmonizes to C# – D#m – Fm – F# – G# – A#m – C°; C# minor to C#m – D#° – E – F#m – G#m – A – B. Each chord links to its Octave Mandolin shapes, so backing a tune in C# 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.
