Progressions — Charango
Pick a key — its chords arrive charted on GCEAE, ready to rake.
Every key's diatonic chords, charted as real Charango voicings. Pick a key below and its chord family arrives on GCEAE, ready to rake behind a singer, under a wind line, or alone until the stroke pattern locks.
A huayño or a carnavalito set can spend a whole verse on one two-chord loop. Owning a key here means knowing which shapes the loop touches and keeping the stroke even while the ensemble stacks everything else on top of it.
