The problem with this is that it won't deal with what is probably the best known and most used shapenote system, i.e. the system used in Sacred Harp singing. Here, the note shapes are not attached to specific notes, but to scale positions. So the tonic is always a triangle, the second the normal shape, the third a square and the fourth a diamond. The sequence repeats itself in the upper tetrachord of the scale. To make this a little more complicated, the system takes no account of modes, and so the shapes are attached to the same notes in Am as they would be in C (i.e. C is reckoned to be the first note of the scale for any key signature that doesn't have sharps or flats, regardless of where the tonic actually is.) To do this, a program would have to take into account the K: field, and shape the notes accordingly. Phil Taylor ------------------------ Yahoo! Groups Sponsor --------------------~--> Get Bzzzy!
