Whether you're a guitarist, producer, or someone learning to play for the first time, having the right reference tools can make a real difference. These free browser-based music utilities cover practice, theory, and production — no app download required.
Metronome — A precise, adjustable metronome for keeping time during practice. Set the BPM with a slider or type it directly. Choose between different time signatures (2/4, 3/4, 4/4, 6/8). The click sound is generated with the Web Audio API for low latency, even at fast tempos.
BPM Tap Tempo — Tap the button in time with any song and the tool calculates the BPM for you. Useful when you hear a track and want to know its tempo before you start playing along or building a loop.
Instrument Tuner — Tune guitar, bass, ukulele, violin, or any other instrument using your device's microphone. The tuner detects the pitch in real time and shows you how far off each note is. Works in any modern browser with microphone permission.
Chord Progression Generator — Generate chord progressions in any key and mode (major, minor, dorian, phrygian, and more). Each progression comes with playable chord diagrams. Great for songwriting when you need a fresh starting point.
Music Scale Generator — Look up any musical scale — major, natural minor, harmonic minor, pentatonic, blues, whole tone, and dozens more. Shows all the notes in the scale across the fretboard or keyboard.
Drum Machine — A step-sequencer drum machine with kick, snare, hi-hat, and percussion tracks. Program beats by toggling steps, adjust the BPM, and hit play. Great for sketching out rhythm ideas without any DAW.
Frequency to Note Converter — Enter a frequency in Hz and find out which musical note it corresponds to, and how many cents away it is from perfect pitch. Useful for instrument makers and audio engineers.
Music Interval Calculator — Calculate the interval between any two notes. Useful for music theory students learning to identify and build intervals by ear and on paper.
All tools run entirely in your browser. The tuner and drum machine use the Web Audio API. No plugins, no downloads, no sign-up.
