I was at the music store an hoyur ago and the OWNER was busy with the kids lessons and there was hired help behind the counter. busy those teachers are. My son and I were looking at the collection of left handed guitar's, which there was a whopping 1 hanging on the wall. I looked around at the trumpet books and there was the Standard of Excellence books and there was the new thing with that book...a computer program??? that assists you in learning??? I play a note or play a song near the computer and it records it and grades it??? Gives me a printed evaluation?? that's new to me, what is this??? I might want to go back and get that book if its any thing worth my time. but then, that is gonna have many opinions from the forum indeed. YES??
