Re: double stem

[Mats Bengtsson]

How about the following?

doublestem = #(define-music-function (parser location m) (ly:music?)
#{ << \voiceOne $m \new Voice { \voiceTwo $m } >> \oneVoice #})

\relative c'{ c2 d \doublestem e f \doublestem { g a b c } }

This function applies to the note (or music expression) following it, so 
in this example
you get a double stem in the e and on the sequence g a b c.
