My Eyes Have Seen You

183 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 94% — put it in E minor, a key signature of 1 sharp. The tempo printed above is the median of the 183 readings; 98% of them land within 2% of it, and they barely differ at all.

At 134.7 BPM one beat lasts 445.4 milliseconds, so a sixteenth note is 111.4 ms and a dotted eighth 334.1 ms — the delay times for this recording. Counted half as fast it is 67.4 BPM, counted twice as fast 269.4. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 446.1 Hz, which is 24 cents above 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 5.97 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 0.735 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
