Start the microphone, then pluck one string at a time. Let the note ring clearly and avoid touching other strings. If the tuner says Flat, tighten the string slightly. If it says Sharp, loosen it. When the meter sits near the center and the tuner says In Tune, move to the next string. -
An Online Guitar Tuner helps guitarists quickly check the pitch of each string using their computer or mobile device microphone. Instead of tuning completely by ear, the tuner listens to your guitar, identifies the nearest musical note, and shows whether the string is flat, sharp, or in tune.
For standard guitar tuning, the six strings are tuned to E2, A2, D3, G3, B3, and E4 from the lowest string to the highest. Start the microphone and pluck one string at a time, allowing the note to ring clearly. The tuner displays both the detected note and its frequency in Hertz (Hz).
The cents reading shows how far the detected pitch is from the nearest perfectly tuned note. A negative value means the string is flat, while a positive value means it is sharp. When the reading moves close to zero cents, the string is approaching its correct pitch.
For more reliable results, tune in a quiet room and mute the strings you are not currently checking. Background music, conversation, amplifiers, and other instruments can interfere with microphone pitch detection.
It is also a good idea to check each string again after tuning the entire guitar because changing the tension of one string can slightly affect the others.
Tip: Always approach the target pitch from slightly below when possible. If a string is too sharp, loosen it a little below the correct note and then slowly tighten it back into tune.
