Sense of Doubt

239 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 86% — put it in A minor, a key signature of no sharps and no flats. The tempo printed above is the median of the 239 readings; 94% of them land within 2% of it, and the middle eight tenths of them run from 129.5 to 132.1 BPM.

At 131.6 BPM one beat lasts 455.9 milliseconds, so a sixteenth note is 114 ms and a dotted eighth 341.9 ms — the delay times for this recording. Counted half as fast it is 65.8 BPM, counted twice as fast 263.2. 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 5.78 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 0.063 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
