Music tools are free online utilities that help you practice, write, and understand music — no app or sign-up required. This category collects browser-based theory helpers, practice aids, and tuning calculators that musicians reach for every day. Everything runs on your device, so there is nothing to install and nothing to upload.
For practice, the Online Metronome clicks out a steady tempo at any BPM, and the BPM Tap Counter measures the tempo of a song when you tap along to it. For writing and learning, the Scale Finder lists the notes in any scale or mode, the Guitar Chord Finder shows fingerings for a chord, and the Circle of Fifths Tool maps how keys relate so you can pick chords that fit.
You will also find tuning and frequency math here — note-to-frequency converters, interval ratios, and equal-temperament and just-intonation calculators — useful for sound design and instrument setup. For recording and mixing math like sample rate or file size, see Audio Tools; for room and reverb calculations, see Acoustics Tools.
