beaming

[simon blackmore]

Sorry that this is my second cry for help in the last week.

I am just trying to get my head around changing beaming.

Basically I want to display 8 8th notes in pairs, rather than the current default 2 groups of 4.

I thought this might work 

\set beatGrouping = #'(2 2 2 2)

c8 c8 c8 c8 r8 c8 c8 r8 

But doesn't seem to.

I have been going through the manual and thought the example below would be a good start. But all of the

examples I have tried from this page. seem to just end up without beaming at all.

http://lilypond.org/doc/v2.12/input/lsr/lilypond-snippets/Rhythms

So for example the following code just displays 8 single notes above 8 single notes.

\score {

  \new Staff <<

    \time 7/8

    \new Voice {

      \relative c'' {

        \set Staff.beatGrouping = #'(2 3 2)

        a8 a a a a a a

      }

    }

    \new Voice {

      \relative c' {

        \voiceTwo

        \set beatGrouping = #'(1 3 3)

        f8 f f f f f f

      }

    }

  >>

}

Thanks for having a look

Best wishes

Simon
