Definitions: Tab: a way of writing pitches as numbers of lines in guitar music. Fretboards: a graphical way of describing the fingering necessary to play a given chord. > This sounds like a conventional staff with fretboards above it again.

Given the personal responses I have received so far I am going to simply be working towards making a way to use the guitar tab editor to create a fretboard that can be displayed in the notation editor. Once that has been done to everyone's satisfaction we can talk about the next step. What needs to be done: 1. Change the Chord, Fingering, Barre and Note class so that a small fretboard image is created from the given chord information. 2. Connect the Notation editor with a gui used to select which chord to display. In regards to #1 I have a question about the notation editor. How would an item, like a graphic image representing the guitar chord, be added to the sheet music displayed in the notation editor? My idea is to create a small size image, e.g. 20 pixels x 20 pixel, of the fretboard. After which I can simply add it to the canvas of the notation editor. In regards to #2 I am not sure how to interface the data contained in the chord map inside the guitar tab editor with the notation editor so a chord can be selected for display. Stephen
