What the numbers say

507 independent analyses of this recording were submitted to AcousticBrainz. A bare majority of them — 71% — put it in G sharp minor, a key signature of 5 sharps. The tempo printed above is the median of the 507 readings; 90% of them land within 2% of it, and the middle eight tenths of them run from 126.3 to 129 BPM.

At 126.6 BPM one beat lasts 473.9 milliseconds, so a sixteenth note is 118.5 ms and a dotted eighth 355.5 ms — the delay times for this recording. Counted half as fast it is 63.3 BPM, counted twice as fast 253.2. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 451.8 Hz, which is 46 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 3.92 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 0.914 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 G sharp 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 G♯ minor

Each of these differs from G♯ 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.
