Les derniers seront les premiers

203 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 100% — put it in C major, a key signature of no sharps and no flats. The tempo printed above is the median of the 203 readings; 100% of them land within 2% of it, and they barely differ at all.

At 125.2 BPM one beat lasts 479.2 milliseconds, so a sixteenth note is 119.8 ms and a dotted eighth 359.4 ms — the delay times for this recording. Counted half as fast it is 62.6 BPM, counted twice as fast 250.4. A score would mark that Allegro, 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 6.43 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 0.462 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
