What the numbers say

184 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 89% — put it in E flat minor, a key signature of 6 flats. The tempo printed above is the median of the 184 readings; 72% of them land within 2% of it, and the middle eight tenths of them run from 110.9 to 125.4 BPM.

At 113.9 BPM one beat lasts 526.8 milliseconds, so a sixteenth note is 131.7 ms and a dotted eighth 395.1 ms — the delay times for this recording. Counted half as fast it is 57 BPM, counted twice as fast 227.8. A score would mark that Moderato, by the ranges this site uses.

The analyses put the reference pitch of the recording at 442.9 Hz, which is 11.5 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 5.73 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 0.461 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 E flat 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.

Keys that fit with E♭ minor

Each of these differs from E♭ 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.
