novice questions - an advice appreciated!

[Rob Torop]

I'm trying to create something like this:

• Chord names (not grids) above the first staff
• One normal staff
• One guitar tab staff underneath it (same melody as in staff above)
• Lyrics underneath the guitar tab
  
• Chord grids printed just once at bottom

I would also like to define my own chord voicings with custom names - that is, I don't want to give an alternative voicing for E, but instead make up a new name like EBlah, and have EBlah appear in the chart and in the chord grid. I might have multiple voicings that are all really E so it doesn't work to just re-use E.

I can find bits and pieces of this, but I can't make anything really work.  Here's my work-in-progress (using frescobaldi):

\version "2.18.2"

\include "predefined-guitar-fretboards.ly"

chordNames = \chordmode { c1:m7 ees1:maj7 }

melody         = \relative c'    { c2 f4 bes,4 ees aes, des ges, }

verse            =  \lyricmode  {  I met a fair young maiden }

\score {

  <<

    \new ChordNames \chordNames

    \new FretBoards \chordNames

    \new Staff \melody

    \addlyrics \verse

    \new TabStaff \melody

  >>

}
