You and I

175 independent analyses of this recording were submitted to AcousticBrainz. A bare majority of them — 67% — put it in D major, a key signature of 2 sharps. The tempo printed above is the median of the 175 readings; 66% of them land within 2% of it, and the middle eight tenths of them run from 91.7 to 134.6 BPM.

At 134.4 BPM one beat lasts 446.4 milliseconds, so a sixteenth note is 111.6 ms and a dotted eighth 334.8 ms — the delay times for this recording. Counted half as fast it is 67.2 BPM, counted twice as fast 268.8. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 436 Hz, which is 16 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 4.37 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 0.732 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
