Waiting in Vain

258 independent analyses of this recording were submitted to AcousticBrainz. A bare majority of them — 64% — put it in C major, a key signature of no sharps and no flats. The tempo printed above is the median of the 258 readings; 99% of them land within 2% of it, and they barely differ at all.

At 156.3 BPM one beat lasts 383.9 milliseconds, so a sixteenth note is 96 ms and a dotted eighth 287.9 ms — the delay times for this recording. Counted half as fast it is 78.2 BPM, counted twice as fast 312.6. A score would mark that Vivace, by the ranges this site uses.

The analyses put the reference pitch of the recording at 443.7 Hz, which is 14.5 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 5.9 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 0.851 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
