Spanish Castle Magic

183 independent analyses of this recording were submitted to AcousticBrainz. A bare majority of them — 73% — put it in C minor, a key signature of 3 flats. The tempo printed above is the median of the 183 readings; 80% of them land within 2% of it, and the middle eight tenths of them run from 93.2 to 98.6 BPM.

At 98.4 BPM one beat lasts 609.8 milliseconds, so a sixteenth note is 152.4 ms and a dotted eighth 457.3 ms — the delay times for this recording. Counted half as fast it is 49.2 BPM, counted twice as fast 196.8. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 440 Hz, which is 0 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 3.18 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 0.936 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
