Isn’t It Midnight

139 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 99% — put it in B minor, a key signature of 2 sharps. The tempo printed above is the median of the 139 readings; 78% of them land within 2% of it, and the middle eight tenths of them run from 141.5 to 145.4 BPM.

At 145.3 BPM one beat lasts 412.9 milliseconds, so a sixteenth note is 103.2 ms and a dotted eighth 309.7 ms — the delay times for this recording. Counted half as fast it is 72.7 BPM, counted twice as fast 290.6. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 452.9 Hz, which is 50 cents above concert A at 440 Hz — far enough that playing along at 440 Hz will sound wrong. That is a fact about this transfer of the music, not about how it was played.

The dynamic complexity of the recording measures 2.99 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 0.936 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
