One can, of course, use existing notation. However, I find myself working more like a guitar player starting from chord progressions and using an appropriate scale.
That said, I've been giving some thought to what notation might be more appropriate to the Alpha, particularly in a chromatic scale.
Perhaps the Alpha is better suited to an intervalic form of notation such as this one: A Chromatic Staff. In other words, use a staff that simply lays out a single course of keys and relying on the player to 'fold' up a course every 5th? This would, at least, recognize that the Alpha does not have a piano-like layout. (If you think about it, the standard staff models a piano quite well with sharps and flats telling you to use the black keys).
It might also be possible to code in the course as a number (like guitar TAB) although this either puts some constraints on the keygroup setup or relies on the player to do a translation. (If one ignores the number, it looks just like the chromatic staff above, so there is nothing lost by adding course use suggestions that might be 'wrong' for a particular keygroup or improved on by a particular player)
I'll have to translate some song into such a notation as an experiment. Unless some king soul knows of some software that will do this??
Here is a link to triads notated in several ways. It strikes me that most of the chromatic staffs would be better suited to the Eigenharps. Triad Comparisons
