Frank: I see what you mean, but where I am coming from is that I have already worked out the inversions, and the positions, I just need an easy way to write them down.

For example - in Modal C (CGCGCD) there are an awful number of ways to play a note (the different 'weights') in different positions. Add in the fact that many of the played chords are 'starved' chords (two or three fingers), they need to be noted down in chord boxes.

In open tunings, where the open strings often act as sympathetic resonators or drone strings, the name of the chord is essentially meaningless. This is the problem AL Lloyd referred to when he described conventional notation as 'Piano Tuners Music'.

Mind you TAB is a nightmare too. Not that it doesn't work - it just takes an age to write down!

Hope this makes sense.
