163 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 97% — put it in D flat major, a key signature of 5 flats. The tempo printed above is the median of the 163 readings; 79% of them land within 2% of it, and the middle eight tenths of them run from 156.4 to 161.6 BPM.

At 161.6 BPM one beat lasts 371.3 milliseconds, so a sixteenth note is 92.8 ms and a dotted eighth 278.5 ms — the delay times for this recording. Counted half as fast it is 80.8 BPM, counted twice as fast 323.2. A score would mark that Vivace, by the ranges this site uses.

The analyses put the reference pitch of the recording at 434.2 Hz, which is 23 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 2.95 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 0.899 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
