[tablatures] Power chords

[Patrick Schmidt <p.l.schmidt@xxxxxx>]

Hi all,

here is a solution for typesetting power chords and their symbols.  
The solution is not new and I didn't invent it but including the  
little file makes life a tiny bit easier. Maybe these few lines of  
code could become part of the lilypond bundle thus making it  
unnecessary to have to include them in each and every file containing  
power chords??? Where would they have to go?

The following example shows that there are quite a few ways of coding  
power chords. Personally I like using for example c1:1.5 or c1:1.5.8  
for two- and three-voiced power chords as it's short and shows  
clearly which steps are in the chord. If no one objects I could offer  
to add a few lines of text to the manual concerning power chords??!!  
Is it worth adding this example to the snippet repository?

\version "2.13.33" % on Mac OS X

\include "powerchords.ly"

ChordsAndSymbols = \chordmode {
  \set chordNameExceptions = #powerChords
  \set minimumFret = #3
  c,1^3
  d,1:5^3
  c,1:5.8^3
  \set minimumFret = #1
  f,,1:5.8^3
  g,,1:8^3.7
  \set minimumFret = #8
  c,1:1.5
  c,1:1.5.8
  \set minimumFret = #3
  f,1^3
  f,1:5.8^3
  bes,1:5.8^3
  \set minimumFret = #0
  a,,1:5.8^3
  e,,1:5.8^3
}

\score {
  <<
    \new ChordNames { \ChordsAndSymbols }
    \new Staff {
      \clef "treble_8"
	    \ChordsAndSymbols
    }
    \new TabStaff {
      \ChordsAndSymbols
    }
  >>
}

Thanks for any feedback!
