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
237 independent analyses of this recording were submitted to AcousticBrainz. Fewer than half of them — 48% — put it in B major, a key signature of 5 sharps. The tempo printed above is the median of the 237 readings; 18% of them land within 2% of it, and the middle eight tenths of them run from 106.3 to 163.6 BPM. That is a recording the detector cannot settle on — the readings are spread far enough that the median is a summary of a disagreement rather than a measurement anybody should trust to the decimal.
At 123.3 BPM one beat lasts 486.6 milliseconds, so a sixteenth note is 121.7 ms and a dotted eighth 365 ms — the delay times for this recording. Counted half as fast it is 61.7 BPM, counted twice as fast 246.6. 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 6.38 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 0.183 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 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.
