20th Century Fox Fanfare

165 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 90% — put it in B flat major, a key signature of 2 flats. The tempo printed above is the median of the 165 readings; 35% of them land within 2% of it, and the middle eight tenths of them run from 109.5 to 144.7 BPM.

At 112.4 BPM one beat lasts 533.8 milliseconds, so a sixteenth note is 133.5 ms and a dotted eighth 400.4 ms — the delay times for this recording. Counted half as fast it is 56.2 BPM, counted twice as fast 224.8. A score would mark that Moderato, by the ranges this site uses.

The analyses put the reference pitch of the recording at 439 Hz, which is 4 cents below 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 6.68 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 0.881 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
