I'm really glad to connect with a music teacher (how long have you been teaching?) and music lover and i have dully noted your advise :) About communicasound, i have launch this project two years ago and i work everyday on it on the other social platforms for free :) It's a huge amount of work and time but i really want people who can't afford it to learn music theory and music with the best contents. I look forward to reading and supporting your next posts. Have a great evening. Peace. CS
