Almost Blue

144 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 99% — put it in A minor, a key signature of no sharps and no flats. The tempo printed above is the median of the 144 readings; 97% of them land within 2% of it, and the middle eight tenths of them run from 123.4 to 125.8 BPM.

At 125.5 BPM one beat lasts 478.1 milliseconds, so a sixteenth note is 119.5 ms and a dotted eighth 358.6 ms — the delay times for this recording. Counted half as fast it is 62.8 BPM, counted twice as fast 251. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 440.3 Hz, which is 1 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 7.9 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 0.487 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
