I made these videos a while ago for the Iowa Music Teacher Association, following their curriculum. More videos that were interactive (with quiz questions and multiple choice answers) were hosted on TechSmith (Camtasia) but are now defunct as I now live in California. Levels are A to F on the YouTube channel. Answers are in a google document that can be shared if you email DoLearnMusic@gmail.com
Look for Mindful Music Academy Facebook page.
