About these tools

Practise smarter between lessons

Our teachers use these tools with students every week. The tuner gets you in tune in seconds, the metronome's speed and silent-bar trainers build clean, steady timing, and the tanpura gives Hindustani vocal and instrumental students a proper drone for riyaaz.

Everything runs in your browser. The tuner listens only while it is switched on and never records or uploads anything.

How do I use the online tuner?

Press Start tuner and allow microphone access. Play one string or note at a time, close to your phone or laptop. The needle schools and turns green when you are within 5 cents of the note. Pick your instrument to see its strings and hear each reference pitch.

What is standard guitar tuning?

From the thickest string to the thinnest: E, A, D, G, B, E (E2 A2 D3 G3 B3 E4). Bass guitar is E, A, D, G, an octave below the guitar's four lowest strings, and ukulele is usually G, C, E, A.

What tempo should I practise at?

Start slowly enough to play the passage perfectly, often 60 to 70% of the target tempo, then raise it a few BPM at a time. The speed trainer does this for you: it adds a set number of BPM every few bars until it reaches your target.

What is the silent-bar trainer for?

It plays a few bars, then goes quiet for a bar or two while you keep playing. When the click comes back, you can hear whether you rushed or dragged. It is one of the best ways to build an internal sense of time.

How do I use the tanpura drone?

Choose your Sa (the tonic you sing or play from), pick Pa, Ma or Ni for the first string, and start the drone. Practise your swaras, alankars and ragas against it to train pitch and sur.

Is the microphone recording me?

No. The tuner analyses sound in your browser only. Nothing is recorded, uploaded or stored, and the microphone switches off when you stop the tuner or leave the page.
