Tune your guitar using your microphone with visual pitch detection for standard and alternate tunings.
Pluck one string at a time and Chromatic Guitar Tuner listens through the microphone, identifies the sounding pitch, and gives visual guidance toward the note required by the selected standard or alternate tuning. Because it is chromatic, it can recognize notes outside standard guitar tuning rather than assuming only six fixed pitches. The common mistake is watching the note name without checking the selected tuning or string: the same note can be correct for one string and wrong for another. Microphone audio is processed in the browser and is not uploaded.
Choose standard tuning or the intended alternate tuning before adjusting any strings. The selection establishes the target note for each guitar string. Pluck a single string and let it ring clearly so the tuner can compare the detected pitch with the appropriate target rather than with a note from a different tuning.
The visual reading updates as the string vibrates. Adjust the tuning machine in small steps according to whether the detected pitch is below or above the target, then pluck again. Repeat until the display settles at the intended note. Work through the strings individually because simultaneous notes can prevent a stable reading.
Yes. Select Drop D before tuning. Its strings are D, A, D, G, B, E from lowest-pitched to highest-pitched, so only the lowest string changes from standard tuning. Confirm that you are adjusting that string and approaching D in the expected range rather than tightening toward a higher D.
Pitch detection becomes unstable when the microphone hears several strong tones, excessive background noise, or a note that fades too quickly. Mute the unused strings, move closer to the microphone, and pluck one string cleanly. A gentler pluck after the initial attack can also provide a steadier sustained tone.
