How to use Metronome & Instrument Tuner
- Metronome: set the tempo with the slider, the ± buttons or Tap tempo, choose the time signature, clicks per beat and sound, and press Start (or the space bar).
- Tuner: choose your instrument, press Start tuner and allow the microphone, then play one string at a time. The needle shows how many cents sharp or flat you are; green means in tune.
- Tap a string's note to hear a reference tone if you prefer tuning by ear. Change A4 from 440 Hz if your group tunes differently.
What are the limits of Metronome & Instrument Tuner?
Timing uses your browser's audio clock and is steady, but Bluetooth speakers and headphones add a delay. The tuner listens to one note at a time and works best in a quiet room close to the microphone; very low bass notes can take a moment to settle. Sound is analysed on your device and never recorded.
