26 recordings on this site sit at 81 beats per minute once each one's analyses are reduced to their median. A score would call that Andante, by the ranges printed on the data page.

One beat lasts 740.7 milliseconds. That makes an eighth note 370.4 ms, a dotted eighth 555.6 ms and a sixteenth 185.2 ms — the delay times that will sit in time with anything at this tempo.

Half time is 40.5 BPM and double time is 162; a tempo detector that disagrees with this page by a factor of two is usually counting one of those instead.

7 of them are in C major, more than any other key at this tempo.
