In ternary/triplet Music like Blues, Swing and  Boogie the accent is on 
the 2 and 4. (whereas Classic, Latin, Rock and  Folk do have the accent 
on beat 1 and 3. I found that topic interesting for me as well (for 
blues notation) and did some experiments with possible notations. Some I 
have seen in sheet music, not musically perfect. The second line is an 
example of Gershwin " I Got Rhythm ", the first two bars :

\version "2.16.2"


\paper {

indent = 0

line-width = #100

tagline = ##f

}


\layout {

\context {

\Score

\override NonMusicalPaperColumn #'line-break-permission = ##f

proportionalNotationDuration = #(ly:make-moment 1 32)

}

}


\header {

title = "possible swing notation "

composer = "last Line Gershwin: I Got Rhythm "

\newline

}


swing = {

\relative c'' {

\key bes \major




{

\times 2/3 {g8 g g}

% \times 2/3 {(g8 g) g}

\times 2/3 {g8. g8 g16}

% \times 2/3 {[g8 g16]}

\times 2/3 {g4 g8}

r4

}

\break

{

r4 bes2 bes4 bes4. bes8 (bes2)

}

}

}


\score

{

<<

\new Staff {

\swing

}

>>

}


It is impossible to set slurs inside triples. Is a widely used practice 
to mark swing rhythm. And I found it impossible to beam an eighth with a 
sixteenth note. (it is often used, where the second note. the sixteenth 
note does have a short additional (sixteenth) beam - may be my knowledge 
of lilypond does not have the necessary depths for such a construct?)


May be you can convince the developers to allow slurs in triplets to 
mark the swing rhythm? (I do not try it, because my ideas usually are 
disliked.)


BTW I do not think this is a bug, it simply is not implemented. BTW I am 
not sure that the bug blog is the correct place for this topic?
