A#, Held by the Armonía
62 qualities on one root. Pick one for the grip and the section's job with it.
All 62 qualities on the root A#, across 10 families, drawn for this instrument. A son or a ranchera will use three or four of them; the rest are here for the bolero that reaches further.
Inside the armonía this instrument is the top of the armonía — five re-entrant strings whose open third is the highest open pitch on the instrument, so every strum lands as one tight treble block instead of a spread stack, and the shape below is not a voicing choice so much as a section instruction — the whole armonía strikes the same mánico in unison, on the same slot, or the chord stops being one event.
