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

183 independent analyses of this recording were submitted to AcousticBrainz. Fewer than half of them — 45% — put it in A minor, a key signature of no sharps and no flats. The tempo printed above is the median of the 183 readings; 57% of them land within 2% of it, and the middle eight tenths of them run from 80.1 to 161.6 BPM.

At 80.2 BPM one beat lasts 748.1 milliseconds, so a sixteenth note is 187 ms and a dotted eighth 561.1 ms — the delay times for this recording. Counted half as fast it is 40.1 BPM, counted twice as fast 160.4. A score would mark that Andante, 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 3.76 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 0.93 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.

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 A minor

Each of these differs from A 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.
