Fade to Black

146 independent analyses of this recording were submitted to AcousticBrainz. A bare majority of them — 59% — put it in A minor, a key signature of no sharps and no flats. The tempo printed above is the median of the 146 readings; 0% of them land within 2% of it, and the middle eight tenths of them run from 112.7 to 142 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 126.1 BPM one beat lasts 475.8 milliseconds, so a sixteenth note is 119 ms and a dotted eighth 356.9 ms — the delay times for this recording. Counted half as fast it is 63.1 BPM, counted twice as fast 252.2. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 447.2 Hz, which is 28 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 3.52 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 0.877 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
