Working Man

181 independent analyses of this recording were submitted to AcousticBrainz. Fewer than half of them — 44% — put it in A minor, a key signature of no sharps and no flats. The tempo printed above is the median of the 181 readings; 80% of them land within 2% of it, and the middle eight tenths of them run from 143.6 to 154.7 BPM.

At 154.6 BPM one beat lasts 388.1 milliseconds, so a sixteenth note is 97 ms and a dotted eighth 291.1 ms — the delay times for this recording. Counted half as fast it is 77.3 BPM, counted twice as fast 309.2. A score would mark that Allegro, 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 1.43 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 0.963 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
