       | Also found this bit particularly interesting:

       | > Apart from one other composition--Mozart's Piano Sonata in C
       | Major (K545)--the therapeutic properties of K448 could not be
       | replicated with other musical stimuli. Stimuli previously tested
       | were other Mozart compositions, Beethoven's Fur Elise, and a
       | string version of K448.

       | While this is cool, two critical points are (a) why no spectral
       | analysis of K448 to determine what parts of the music are
       | responsible for the effect and (b) IEDs are suggestive of the
       | brain region primarily responsible for seizure onset but the jury
       | is still out if they can be used as sole criteria.

         | Transform is bijective, so if you took into account details in
         | phase I guess you're right.

         | recordings of the same performance. It would seem more likely
         | that the musical contents would somehow be the relevant factor,
         | although this is speculative, of course.

         | I'd start by changing speed, try various frequency shaping (eg,
         | squashing the treble), a version done in MIDI with pure tones
         | rather than wavetable), try midi with wavetable, but with
         | successively bigger changes to the tone, try playing various
         | subsections on repeat, etc.
