I thought I had it this time. I came up with a great idea that I’d never heard of before. I was going to design a new notebook-sized product that would electronically store and display sheet music for musicians. It would advance from page to page with a foot pedal, be modular so that you could have up to four screens side by side, and store gazillions of pieces of sheet music. Problem is, a number of other people have already thought of all that, and more, and are currently selling them.  Look at  http://www.musiciansfriend.com. I know, I’ll tweak the idea by integrating it into a piano, and sell the idea to OEM’s. Except that there’s already a patent for that. Who knows, maybe I’ll get one for my piano-playing wife someday. Once I can afford it.
