134 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 86% — put it in C minor, a key signature of 3 flats. The tempo printed above is the median of the 134 readings; 78% of them land within 2% of it, and the middle eight tenths of them run from 84 to 165.8 BPM.

At 84 BPM one beat lasts 714.3 milliseconds, so a sixteenth note is 178.6 ms and a dotted eighth 535.7 ms — the delay times for this recording. Counted half as fast it is 42 BPM, counted twice as fast 168. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 440.3 Hz, which is 1 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 5.18 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 0.798 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
