A composer I know is looking for some information on tone rows generated by
computer.  Specifically he is looking for means of generating tone rows
through a program, such that the tone rows produced would contain every
possible interval.  In other words (if I understand him correctly) he is
looking for computer generated tone rows that contain all possible intervals
(from minor second to major seventh [obviously not including the octave])
between adjacent notes in the tone row.

In analyzing this requirement, it seems that it is a difficult proposition
to attempt to create such a tone row without tripping over yourself by
repeating a note.  The big pitfall is using successive intervallic
relationships that wind up totalling exactly an octave (e.g., minor second,
fourth, tritone).

Does anyone have either examples of tone rows like those I describe or a
means of generating them through a program?  Thanks in advance for any help
you may be able to offer.

(P.S. We expect that the resulting rows would be "symmetrical", but I'm not
exactly sure what I mean by "symmetrical", or if indeed they would be
symmetrical in *any* sense of the word.)
