All Right Now

155 independent analyses of this recording were submitted to AcousticBrainz. A bare majority of them — 59% — put it in A major, a key signature of 3 sharps. The tempo printed above is the median of the 155 readings; 97% of them land within 2% of it, and the middle eight tenths of them run from 120 to 121.2 BPM.

At 120.8 BPM one beat lasts 496.7 milliseconds, so a sixteenth note is 124.2 ms and a dotted eighth 372.5 ms — the delay times for this recording. Counted half as fast it is 60.4 BPM, counted twice as fast 241.6. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 440.3 Hz, which is 1 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 4.55 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 0.83 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
