Love Is a Rose

156 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 100% — put it in C major, a key signature of no sharps and no flats. The tempo printed above is the median of the 156 readings; 99% of them land within 2% of it, and the middle eight tenths of them run from 142.7 to 143.9 BPM.

At 143.5 BPM one beat lasts 418.1 milliseconds, so a sixteenth note is 104.5 ms and a dotted eighth 313.6 ms — the delay times for this recording. Counted half as fast it is 71.8 BPM, counted twice as fast 287. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 439.5 Hz, which is 2 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 6.39 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 0.597 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
