WYSIWYP solves all three main challenges of reading Traditional Notation (staff consistency, key signatures, tempo).
Closing the deal
The points that I made in the pitch for Alternative Notations in general are so important, I'll repeat them here:
These points emphasize young students because they are going to be the main target audience for the adoption of any new Alternative Notation. Trying to convince readers of Traditional Notation to switch is mostly a lost cause (OK maybe there are a few exceptional cases). But the point is that I think open-minded young beginners will pounce on a new notation if it is easy to read. And because of social media, good ideas can quickly go viral.
In addition to these selling points, I also point out that the availability of SNapp enables an evaluation study right away.
Bottom line: There's a receptive audience waiting, WYSIWYP is worth a look (IMHO), and it's ready to go. So act now to get your free Ginsu knives.
