253 independent analyses of this recording were submitted to AcousticBrainz. A bare majority of them — 69% — put it in C major, a key signature of no sharps and no flats. The tempo printed above is the median of the 253 readings; 96% of them land within 2% of it, and the middle eight tenths of them run from 100.3 to 101.5 BPM.

At 100.9 BPM one beat lasts 594.6 milliseconds, so a sixteenth note is 148.7 ms and a dotted eighth 446 ms — the delay times for this recording. Counted half as fast it is 50.5 BPM, counted twice as fast 201.8. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 441 Hz, which is 4 cents above 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 7.51 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 0.319 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
