I found some music books and some software that tremendously accelerated my son's guitar playing skills. I can ask him for a reference if your son or daughter is interested. I sat first seat in the trumpet section from 4th grade until 10th grade when I swapped band for a chemistry class that I would need to get into UCSD. I also played baritone and french horn as necessary. My 20 year old has my "good" trumpet in San Diego. He sat first seat through high school as well. The Marines assigned him to bugling duties while he was in boot camp.
Yes please I need this kind of help! Mail it to me and also what state your in ;)
