What the numbers say

323 independent analyses of this recording were submitted to AcousticBrainz. A bare majority of them — 52% — put it in A minor, a key signature of no sharps and no flats. The tempo printed above is the median of the 323 readings; 98% of them land within 2% of it, and they barely differ at all.

At 98.3 BPM one beat lasts 610.4 milliseconds, so a sixteenth note is 152.6 ms and a dotted eighth 457.8 ms — the delay times for this recording. Counted half as fast it is 49.2 BPM, counted twice as fast 196.6. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 439.7 Hz, which is 1 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 3.68 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 0.887 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 A minor; 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.

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.
