Keep 29 music tools together, with core calculations available offline. Free download; optional one-time Remove Ads purchase.
Use this English web toolkit to practise rhythm, explore harmony and calculate timing. For example, 120 BPM means 500 milliseconds per quarter-note beat. The metronome, circle of fifths and calculator tools run in your browser; audio analysis uses your device.
Select a tool, enter your values and check its worked example and assumptions before using the result. Tempo calculations assume the displayed beat unit; royalty estimates are scenarios, not guaranteed payments.
