What the numbers say
255 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 89% — put it in G major, a key signature of 1 sharp. The tempo printed above is the median of the 255 readings; 85% of them land within 2% of it, and the middle eight tenths of them run from 153.6 to 163.6 BPM.
At 153.8 BPM one beat lasts 390.1 milliseconds, so a sixteenth note is 97.5 ms and a dotted eighth 292.6 ms — the delay times for this recording. Counted half as fast it is 76.9 BPM, counted twice as fast 307.6. A score would mark that Allegro, by the ranges this site uses.
The analyses put the reference pitch of the recording at 439.2 Hz, which is 3 cents below concert A at 440 Hz — close enough to standard that a tuner would not argue. That is a fact about this transfer of the music, not about how it was played.
The dynamic complexity of the recording measures 2.35 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 0.933 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 G 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 G major
Each of these differs from G 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.
