162 recordings on this site sit at 123 beats per minute once each one's analyses are reduced to their median. A score would call that Allegro, by the ranges printed on the data page.

One beat lasts 487.8 milliseconds. That makes an eighth note 243.9 ms, a dotted eighth 365.9 ms and a sixteenth 122 ms — the delay times that will sit in time with anything at this tempo.

Half time is 61.5 BPM and double time is 246; a tempo detector that disagrees with this page by a factor of two is usually counting one of those instead.

18 of them are in A major, more than any other key at this tempo.
