Guinnevere

170 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 170 readings; 97% of them land within 2% of it, and the middle eight tenths of them run from 112.5 to 113.9 BPM.

At 112.8 BPM one beat lasts 531.9 milliseconds, so a sixteenth note is 133 ms and a dotted eighth 398.9 ms — the delay times for this recording. Counted half as fast it is 56.4 BPM, counted twice as fast 225.6. A score would mark that Moderato, by the ranges this site uses.

The analyses put the reference pitch of the recording at 436.2 Hz, which is 15 cents below 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 6.55 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 0.101 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
