This is a sawtooth waveform suitable for easily tuning guitar by ear, comprised of 20 seconds each of E-A-D-G-B-E in sequence. Adjust guitar volume to same volume as the tone, ideally through the same audio output. Tune the string close to the tone, then listen for the subtle beat-frequency indicating not-quite-perfect tune. When the beat frequency goes away, your guitar string is in perfect tune.
Also useful for adjustable bridges. The open string and its 12th fret octave will both produce no beat-frequency when the bridge is adjusted properly.
