Private Investigations

134 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 97% — put it in E minor, a key signature of 1 sharp. The tempo printed above is the median of the 134 readings; 7% of them land within 2% of it, and the middle eight tenths of them run from 84.5 to 172.3 BPM. That is a recording the detector cannot settle on — the readings are spread far enough that the median is a summary of a disagreement rather than a measurement anybody should trust to the decimal.

At 152.8 BPM one beat lasts 392.7 milliseconds, so a sixteenth note is 98.2 ms and a dotted eighth 294.5 ms — the delay times for this recording. Counted half as fast it is 76.4 BPM, counted twice as fast 305.6. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 440.8 Hz, which is 3 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 6.78 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 0.023 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
