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

176 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 97% — put it in B major, a key signature of 5 sharps. The tempo printed above is the median of the 176 readings; 97% of them land within 2% of it, and they barely differ at all.

At 132.6 BPM one beat lasts 452.5 milliseconds, so a sixteenth note is 113.1 ms and a dotted eighth 339.4 ms — the delay times for this recording. Counted half as fast it is 66.3 BPM, counted twice as fast 265.2. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 452.6 Hz, which is 49 cents above concert A at 440 Hz — far enough that playing along at 440 Hz will sound wrong. That is a fact about this transfer of the music, not about how it was played.

The dynamic complexity of the recording measures 5.66 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 0.237 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.
