guitar chord/fingerings a la "Ted Greene"
I personally find useful to write little "Ted Greene style" diagrams next to the chord symbols, to remind me a particular finering for a chord progression or passage.
It's based on he usual "grid" chord schema, with the possibility to use dots, squares and triangles (filled and/or just borders) that briefly indicate the note (and finger) sequence in the diagram (e.g., first all the full dots, then the white squares, then the triangles, etc...)
In this way Ted Greene was able to outline fingering details that often on a regular score is quite difficult to render (and read)
An example (using only two symbols, blak and white dots):
The possibility to insert graphic images could be a workaround, but a native way to manage those diagrams would be a real plus (at least for guitarists like me..)
