Hello,
I later discovered that durations other than 16 are required for the doubled
note later in the score (dotted 4th note for example), so I ended up doing
something like this:
GR = #(define-music-function (m p1 p2 p3 p4 p5 p6)
(ly:music? ly:pitch? ly:pitch? ly:pitch? ly:pitch? ly:pitch? ly:pitch?)
#{
<<
$m
\\
{ $p1 16[^( $p2 $p3 $p4 $p5 $p6 ]) }
>>
#})
This makes it necessary to write the first pitch twice, (e.g. \GR f''8 f a, f
a, c, f,) but it’s not a huge deal compared to having to write the whole << {}
\\ {} >> construct every time. Now, on to figure out how to make a nice
“knee’d” beam (3+3) for those notes.
Thanks for the help!
