Music Tools

6 tools, free and without ads.

Tools for practising, tuning and writing music, plus two for when you would rather listen or play than practise. Every sound here is synthesised in the browser as you use it, so nothing streams and nothing is downloaded once a page has loaded.

The tuner listens through your microphone to measure a note. That listening happens on your device and stops when you leave the page; no audio is recorded, stored or sent anywhere.

Which tool for which job

Tuning — the Tuner hears a note and says which it is and how many cents sharp or flat, with presets for guitar, bass, ukulele and violin. The Tone Generator goes the other way and plays a reference pitch to tune by ear, which also makes it a speaker and headphone test: slide the frequency from 20 Hz to 20 kHz, or play into the left or right channel alone.

Keeping time — the Metronome clicks from 20 to 300 BPM with tap tempo, an accented downbeat and subdivisions. Each click is scheduled on the audio clock, so the beat holds steady while the tab is in view; switch to another tab and it stops, because a browser throttles a hidden page too much to keep time.

Writing it down — Staff Paper prints blank manuscript in treble, bass or grand staff, with optional guitar tab, sized for US Letter or A4.

Playing and listening — Piano Hero is a falling-notes game over public-domain tunes, playable on a real keyboard or by touch. The Lo-fi Music Generator composes an endless track live, so it never loops and can be shared as a link.
