Okay, in this one you can freely select which notes to choose from by
changing the list in the top of the program. Don't try to use relative,
or change the format of the list in any way. You are welcome to change
the length of the list, though.

\version "2.10.0"
notes = { c'  cis'  d'  es'  e'  f'  fis'  g'  gis'  a'  bes'  b'
          c'' cis'' d'' es'' e'' f'' fis'' g'' }
\score { {
  #(let* ((random-state (seed->random-state (current-time)))
          (note-list (ly:music-property notes 'elements))
          (num-notes (length note-list)))
    (ly:export
     (make-music 'SequentialMusic 'elements
      (map (lambda x
            (list-ref note-list (random num-notes random-state)))
       (make-list 256)))))
} }
