Born Under a Bad Sign

160 independent analyses of this recording were submitted to AcousticBrainz. Fewer than half of them — 33% — put it in C minor, a key signature of 3 flats. The tempo printed above is the median of the 160 readings; 28% of them land within 2% of it, and the middle eight tenths of them run from 91.7 to 184.6 BPM.

At 95.3 BPM one beat lasts 629.6 milliseconds, so a sixteenth note is 157.4 ms and a dotted eighth 472.2 ms — the delay times for this recording. Counted half as fast it is 47.7 BPM, counted twice as fast 190.6. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 442.8 Hz, which is 11 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 3.06 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 0.794 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
