327 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 95% — put it in F minor, a key signature of 4 flats. The tempo printed above is the median of the 327 readings; 99% of them land within 2% of it, and they barely differ at all.

At 161.8 BPM one beat lasts 370.8 milliseconds, so a sixteenth note is 92.7 ms and a dotted eighth 278.1 ms — the delay times for this recording. Counted half as fast it is 80.9 BPM, counted twice as fast 323.6. A score would mark that Vivace, by the ranges this site uses.

The analyses put the reference pitch of the recording at 440 Hz, which is 0 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 2.88 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 0.942 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
