I've learning to play the sax for just over a month now, and I have been "hooked". I just try to go in my music room and practice whenever I can. Unfortunately I'm still very early in my learning, and I am afraid not to mess things up. My music teacher, whom I visit only once a week told me to try and use some self-learning guide or app, and we would take things further from there. I found an app called tonestro a week ago, and decided to give it a try, since they were offering a free trial for their premium version. To be honest I don't know whether it is because of the app, or simply because I've been practicing every day - but I feel that I'm getting better. I've even tried to take their weekly challenge (and failed miserably) but it has been so nice to improve my playing, and do it in a game type of setting. What are your thoughts on using self-learners on a very early stage? Thanks!
