Hello, I am wondering if anyone has created something similar to what I'm trying to describe. I believe there is probably something like this for the iPhone/Touch, but wondered how difficult it would be to implement on the DS. Basically a guitar chord chart that showed in tablature form where one would place their fingers, the name of the chord, and a sonic demonstration. The user could use a menu to select which key the chord is in, and another to choose major, minior, seventh, diminished, whatever options. I think this would be a really handy tool. If it exists. And if not, someone could make Nintendo DS fame by creating it! On a related note, it would also be cool if there was an e-reader for the DS that had auto-scrolling. One could load guitar tabs in a .txt file and have it scroll down so they had a sheet-music computer handy. It'd certainly be cheaper than this: http://books-videos-music.musiciansfriend....book?sku=423873 Anyway. Thanks for your answers!
