Travelling Riverside Blues

201 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 83% — put it in G major, a key signature of 1 sharp. The tempo printed above is the median of the 201 readings; 87% of them land within 2% of it, and the middle eight tenths of them run from 91.4 to 184.6 BPM.

At 91.4 BPM one beat lasts 656.5 milliseconds, so a sixteenth note is 164.1 ms and a dotted eighth 492.3 ms — the delay times for this recording. Counted half as fast it is 45.7 BPM, counted twice as fast 182.8. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 431.9 Hz, which is 32 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 2.55 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 0.693 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
