Free online chromatic tuner

A chromatic tuner detects any musical pitch, not just the notes of a specific instrument. This makes it ideal for guitar, bass, ukulele, violin, cello, brass, woodwinds, or any other pitched instrument.

Our chromatic tuner analyzes audio from your microphone in real-time, identifies the closest note, and shows you exactly how many cents sharp or flat you are. The visual gauge and green in-tune indicator make it easy to dial in perfect intonation.

Frequently asked questions

A chromatic tuner detects all 12 notes of the chromatic scale (C, C#, D, D#, E, F, F#, G, G#, A, A#, B) across all octaves. Unlike a guitar-only tuner that only recognizes the six open string notes, a chromatic tuner can identify any pitch, making it suitable for every instrument.

Both have advantages. A clip-on tuner reads vibrations directly from the instrument, which makes it better in noisy environments. A microphone-based chromatic tuner like this one requires no hardware and works on any device with a browser. For quiet practice spaces, it's just as accurate.

Yes. Sing or hum into your microphone and the tuner will detect the pitch and show you the closest note with cents offset. It's a great tool for ear training and vocal exercises.
