DOCUMENTATION / TUNER

A tuner helps you match each string to its intended pitch. In standard guitar tuning, the strings are E–A–D–G–B–E from lowest to highest. Flat means the string sounds too low; sharp means it sounds too high. Tuning first makes chords and melodies sound as intended.

Choose a tuning preset, allow microphone access, and pluck one string at a time while watching the pitch meter. Make small adjustments until it settles near the center. You can also play a reference note and match it by ear. The tuner supports alternate tunings, and the reference pitch normally stays at A4 = 440 Hz.
