Questions
How long is one beat at 120 BPM?
One beat lasts 0.5 seconds, so 60 beats fit into a 30 second span. Subdivisions add clicks between the beats without changing the tempo.
Can I use 120 BPM in 6/8 time?
Yes. In 6/8 and 7/8 the BPM counts eighth notes, so 120 BPM gives two eighth notes each second, not two beats.
What BPM is allegro?
It depends on the source. The Wikipedia tempo article gives about 120 to 156 BPM for allegro, and this tool counts 120 to 167 as allegro. Tempo words are loose guides, and ranges vary between sources.
Does the beat drift over time?
No. The clicks are scheduled on the audio clock a little ahead of time, not with a timer for each beat, so the spacing stays even. Bluetooth headphones add a delay you can hear, but it does not change the tempo.
How does tap tempo work?
Tap in time with the music. The tool averages the last four taps and sets that tempo. If two seconds pass without a tap, the next tap starts a new reading.
Does it need an internet connection?
No sound files are used. Every click, wood and beep sound is made live in your browser, and nothing is sent anywhere.
