In 2021 we've been working with the educational platform called SkillBox on an 11 modules video course that leads beginners from basic light and sound physics through intervals and scales up to the level of music composition techniques. Each module consists of 3-5 lessons 15-30 minutes each. We go through all the topics with the use of Chromatone web-apps and different instruments. Learners get custom designed sticker sheets from the company by mail and have some instrumental videos to shoot for the homework.
