Stop and Stare

157 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 80% — put it in E major, a key signature of 4 sharps. The tempo printed above is the median of the 157 readings; 85% of them land within 2% of it, and the middle eight tenths of them run from 92.4 to 118 BPM.

At 92.5 BPM one beat lasts 648.6 milliseconds, so a sixteenth note is 162.2 ms and a dotted eighth 486.5 ms — the delay times for this recording. Counted half as fast it is 46.3 BPM, counted twice as fast 185. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 440.5 Hz, which is 2 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 4.29 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 0.869 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
