What the numbers say

142 independent analyses of this recording were submitted to AcousticBrainz. A bare majority of them — 53% — put it in B flat major, a key signature of 2 flats. The tempo printed above is the median of the 142 readings; 100% of them land within 2% of it, and the middle eight tenths of them run from 140 to 141.2 BPM.

At 141.2 BPM one beat lasts 424.9 milliseconds, so a sixteenth note is 106.2 ms and a dotted eighth 318.7 ms — the delay times for this recording. Counted half as fast it is 70.6 BPM, counted twice as fast 282.4. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 438.5 Hz, which is 6 cents below concert A at 440 Hz — the sort of drift a tape machine or a slightly different mastering leaves behind. That is a fact about this transfer of the music, not about how it was played.

The dynamic complexity of the recording measures 4.34 dB: that is how far the level wanders from its own average, so a small number means a loud, flat master and a large one means a recording that still breathes. Its average loudness is 0.877 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.

10 other recordings here are in B flat major; the ones listed below are the closest in tempo.

Beats per bar are not in this dataset. AcousticBrainz's analysis reports a tempo, a key and a loudness, and no time signature at all, so this page does not print one — a 4/4 here would be a guess dressed as a measurement.

Keys that fit with B♭ major

Each of these differs from B♭ major by at most one accidental, or shares its tonic. That is the whole of what a mixing wheel encodes; here the relations are named instead of numbered.
