A tuner is a device that detects the sound of an instrument and determines whether the pitch is correct. When you play a note, the tuner listens and tells you if the pitch is sharp (too high), flat (too low), or in tune. This helps musicians tune their instruments accurately.
To tune your instrument using the online tuner, click the green microphone button. A message will appear asking for microphone access — allow it so the tuner can hear your instrument. Play a note and adjust the pitch until the tuner indicates it's in tune. When you click the "Turn On" button, you'll be prompted to allow microphone access. Once granted, the tuner will listen to your guitar. Play any string — the chromatic tuner will show the note you're playing and how close it is to being in tune. If it's off, adjust the tuning peg. When the display turns green, you're good to go!
It’s important to tune all strings to the correct pitch. After tuning each string from the first to the sixth (or vice versa), it’s recommended to check them again in reverse order. This is because adjusting one string can affect the overall tension of the neck. For example, if you tune the first string but the others are still loose, tuning the rest may lower the first string’s pitch slightly.
You can finely adjust each string using pitch frequency analysis. Tuning accuracy depends greatly on the microphone’s frequency response and background noise. For rare cases where the mic doesn’t work well, this page also provides sample string sounds for tuning by ear. Regular tuning is essential. Frequent playing, temperature and humidity changes, or long storage can all affect tuning. Even one hour of playing can throw it off. If you haven’t tuned your guitar in over a week, it almost certainly needs tuning. Bookmark this site 🔖 to keep your tuning spot on anytime. Happy playing!
