Mr. Soul

175 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 99% — put it in A major, a key signature of 3 sharps. The tempo printed above is the median of the 175 readings; 100% of them land within 2% of it, and the middle eight tenths of them run from 133.3 to 134.8 BPM.

At 133.6 BPM one beat lasts 449.1 milliseconds, so a sixteenth note is 112.3 ms and a dotted eighth 336.8 ms — the delay times for this recording. Counted half as fast it is 66.8 BPM, counted twice as fast 267.2. A score would mark that Allegro, 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 4.55 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 0.872 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
