Progressions in F — Charango

F major harmonises to F – Gm – Am – Bb – C – Dm – E°; F minor to Fm – G° – Ab – Bbm – Cm – Db – Eb. Each chord links to its Charango voicings, so a phrase in F becomes a short list of shapes before the first repeat.

Most of what a charango plays lives on two or three of these chords at a time — a rasgueo is a loop, not a journey. Choose the pair the tune leans on, set a stroke pattern over them, and let the rake do the work the arrangement expects of it.
