What the numbers say
175 independent analyses of this recording were submitted to AcousticBrainz. A bare majority of them — 50% — put it in B minor, a key signature of 2 sharps. The tempo printed above is the median of the 175 readings; 99% of them land within 2% of it, and the middle eight tenths of them run from 120.9 to 122.1 BPM.
At 121 BPM one beat lasts 495.9 milliseconds, so a sixteenth note is 124 ms and a dotted eighth 371.9 ms — the delay times for this recording. Counted half as fast it is 60.5 BPM, counted twice as fast 242. A score would mark that Allegro, by the ranges this site uses.
The analyses put the reference pitch of the recording at 441.5 Hz, which is 6 cents above 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 3.12 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 0.734 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 minor; 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 minor
Each of these differs from B minor 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.
