Helplessly Hoping

218 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 99% — put it in G major, a key signature of 1 sharp. The tempo printed above is the median of the 218 readings; 93% of them land within 2% of it, and the middle eight tenths of them run from 145.3 to 147.4 BPM.

At 147.2 BPM one beat lasts 407.6 milliseconds, so a sixteenth note is 101.9 ms and a dotted eighth 305.7 ms — the delay times for this recording. Counted half as fast it is 73.6 BPM, counted twice as fast 294.4. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 437.2 Hz, which is 11 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 4.55 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 0.684 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
