Source: AcousticBrainz, dump of 2022-06-23 (CC0) · MusicBrainz core data, 2026-09-17 (CC0) · how each number is measured. Measured up to 23.06.2022 — AcousticBrainz stopped collecting in 2022, so nothing released after that date is here.
What the numbers say
135 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 100% — put it in B flat major, a key signature of 2 flats. The tempo printed above is the median of the 135 readings; 68% of them land within 2% of it, and the middle eight tenths of them run from 87.8 to 178.2 BPM.
At 88 BPM one beat lasts 681.8 milliseconds, so a sixteenth note is 170.5 ms and a dotted eighth 511.4 ms — the delay times for this recording. Counted half as fast it is 44 BPM, counted twice as fast 176. A score would mark that Andante, by the ranges this site uses.
The analyses put the reference pitch of the recording at 441 Hz, which is 4 cents above 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 5.03 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 0.643 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.
