[Rhubarb]

139 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 99% — put it in F sharp minor, a key signature of 3 sharps. The tempo printed above is the median of the 139 readings; 62% of them land within 2% of it, and the middle eight tenths of them run from 111.8 to 126 BPM.

At 125.7 BPM one beat lasts 477.3 milliseconds, so a sixteenth note is 119.3 ms and a dotted eighth 358 ms — the delay times for this recording. Counted half as fast it is 62.9 BPM, counted twice as fast 251.4. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 447.9 Hz, which is 31 cents above 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 4.75 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 0.71 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
