C# 13 — Venezuelan Cuatro

C# 13 stacks C# – D# – E# – G# – A# – B. Every chart below sets those tones on A-D-F#-B and names the fret and finger holding each one — tap a chart to hear it.

Four single nylon strings, no doubling anywhere, and a hand that almost never stops moving. The Venezuelan instrument answers a chord with a block of sound rather than a spread of notes, and the tuning is what forces that: fold the top of the range back inside the sweep and the whole grip arrives at once.

Ordered as they sit under the hand, the open strings climb steadily to the top and then drop a perfect fifth at the very last pair, spanning a major sixth in all — and because of that the highest string is not the outermost one, so a stroke reaches its top note early and the rest of the grip lands underneath it as a block.

That is also what makes the frenado work. Brake the strings at the moment of the stroke and the block turns into a dry snap with no pitch in it — a percussion event a chart cannot draw, which is why the golpe pages declare every one of them instead.

Voicings are computed for this tuning by the shared voicing generator, not borrowed from another instrument; traditional technique may still use idiomatic shapes not charted here.

Then stop practising it as a shape and start practising it as a bar. Set a slow three, put the grip down once, and spend the rest of the bar on the strumming hand alone — where the brake falls decides what the chord sounds like far more than which inversion you picked.
