A# maj7add13 — Guitarrón
A# maj7add13 as shapes on ADGCEA: lowest position first, frets and fingers named, audio on tap.
A# maj7add13 stacks A# – C## – E# – F## – G##. The charts below place those tones on the Guitarrón's ADGCEA strings shape by shape, sorted from the lowest playable position on up — each one names its frets and fingers, and plays on tap.
Voicings are computed for this tuning by the shared voicing generator; traditional guitarrón technique plays octave double-stops rather than block chords, so treat charted grips as reference positions.
Treat the lowest shape as the address and the rest as the route: the same chord repeats along the neck, and choosing WHERE to grab it — near the nut or up where it bites — is most of the craft of rhythm playing.
