Guitar: the Armonía's Chord Reference
62 qualities, twelve roots — the grip, and the section job that comes with it.
The chord reference for this instrument. Pick a root, then any of 62 qualities, and get the grips plus the thing a diagram never carries: which section is holding the chord and what it owes the others while it does.
Inside the armonía this instrument is the bottom of the armonía — the same mánico the vihuela is playing, an octave lower and with more sustain, which is what stops the section sounding thin under a full melody. Nothing here is a solo grip: the value of the shape is that it lines up with the vihuela's, so the pair arrive in unison as one attack with a low half and a high half.
Every shape is drawn for E–A–D–G–B–E across 6 strings, open positions first and movable ones after them, each with playback.
