Cuban Tres is tuned G–C–E, with 15 frets to work with. 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.

Each position shows the scale notes and their intervals from the root so you can connect the shape to its sound, hear it with audio playback, and practice it in any register. Movable patterns let you transpose the same fingering to other keys once it is learned.

Once a position is under your fingers, link the G Phrygian scale to the chords it harmonizes and to progressions in the key of G to start improvising and writing with it. Working a scale alongside its chords is the fastest way to make it stick and to hear how it colors a progression.
