Progressions in A# — Cavaquinho

A# major harmonises to A# – Cm – Dm – D# – F – Gm – A°; A# minor to A#m – C° – C# – D#m – Fm – F# – G#. Each chord links to its Cavaquinho voicings, so a set in A# becomes a short list of shapes before the roda ever starts playing.

Most of what a cavaquinho plays in a roda lives on two or three of these chords at a time — a samba turnaround loops, it does not wander. Choose the pair the tune leans on, pick a batida cell to chop them with, and let the repetition carry the rest.
