What the numbers say

171 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 96% — put it in F sharp major, a key signature of 6 sharps. The tempo printed above is the median of the 171 readings; 99% of them land within 2% of it, and the middle eight tenths of them run from 145.1 to 146.3 BPM.

At 146.3 BPM one beat lasts 410.1 milliseconds, so a sixteenth note is 102.5 ms and a dotted eighth 307.6 ms — the delay times for this recording. Counted half as fast it is 73.2 BPM, counted twice as fast 292.6. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 435.2 Hz, which is 19 cents below 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 5.48 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 0.641 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 F sharp 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 F♯ major

Each of these differs from F♯ 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.
