231 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 100% — put it in G major, a key signature of 1 sharp. The tempo printed above is the median of the 231 readings; 71% of them land within 2% of it, and the middle eight tenths of them run from 83.6 to 166.4 BPM.

At 83.6 BPM one beat lasts 717.7 milliseconds, so a sixteenth note is 179.4 ms and a dotted eighth 538.3 ms — the delay times for this recording. Counted half as fast it is 41.8 BPM, counted twice as fast 167.2. A score would mark that Andante, 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 4.39 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 0.482 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
