RE: Just a fun example of what Lilypond can do

Hi,

If you want better control over tuplet brackets and their angles, here's
some useful code.
You can get the brackets horizontal with little effort using this.

[Not my code, but I am unable to recall who created this to acknowledge
them.]

[Do tell us your name, it would be good and proper. Even a pseudonym is
better than nothing. ]

No bugs, no problems with this score. Thought I'd just toss this out there
to show a neat example of some things Lilypond can do that no other notation
program (that I know of -- haven't used SCORE) can do.
