Tap any shape to identify it instantly, then swim through curated and generated options until something actually feels right under your hand.

Fretboard Trainer Pro is an interactive GCEA map that turns the neck into something you read, touch, and hear instead of a wall chart to memorize. Pick a root and quality and the board lights up with scales and chords so spellings, shapes, and sound stay tied together. Color pitch classes, flip ♯ or ♭ naming to match your charts, and drill with Name the note or Find the note until the neck feels like familiar ground. It runs touch-first in the browser on phone, tablet, or desktop—no install, no account, just open and teach, practice, or demo.

Chord Trainer Pro trades endless chord posters for short rounds that actually train your eyes, ears, and fingers at once.

GCEA and baritone DGBE are built in so you practice in the tuning you really play.
