Online chromatic tuner for any instrument
Any instrument, any note: the chromatic tuner names the nearest semitone and shows how many cents off you are.
What is a chromatic tuner?
It recognises all 12 semitones rather than only fixed strings, so it works for wind, brass, voice and any tuning.
Reference pitch
A4 = 440 Hz is standard; some orchestras use 442–443 Hz and baroque ensembles 415 Hz.
Cents explained
A semitone is 100 cents.
