I have tweaked my recorder program so that it is running well and for the past five years, every 5th grader has achieved a black belt in recorder, a major accomplishment. Get my black belt program free HERE. Many have passed off 20 to 70 more songs and most are able to read notes well by the end. One thing I need to do to improve the program is to get more students reading notes before we start recorder, especially those who struggle at reading.
