Reference tones for the three G–C–E courses, one at a time, plus a mic tuner where your browser allows it.

Metronome

A steady click from 30 to 280 BPM with accented downbeats — from bolero-slow to descarga tempo.

Practice

Theme Builder

Give the metronome a job: the three cells played dead even · daily picking drills · chord changes that don’t stop the figure · scale maps. Every tool runs in the browser — nothing to install, nothing to sign up for.
