Funny. I went into University wanting to double major in Composition and Music Education.
I dropped out of Composition after one semester.
I grew tired of my professor telling me that I should make it sound like this, instead of giving me direction on ways to improve my skills as a composer, instead of trying to shape my style into a pre-made mold.
I'm glad that you are continuing to do music! For some (many of my friends), dropping music was the only thing that saved their love for it. Though I know many composers who practically ignored their professors wishes and wrote their own stuff, haha.
A good thing to is to check out some prominent ambient composers to get an idea of different techniques you could use in your music. For timbres, and stuff.
A couple of good ones are Thomas Newman, and one that I recently got into was Jonsi and Alex. Of course, I wouldn't simply stick to them! There are multitudes of great artists out there!
I actually majored in Music with only one and a half years of basic knowledge. So yeah, I had to work my way around things to graduate on time. And that one thing was exactly what you said about the composition professor. I actually emailed him telling him I didn't like a certain project and showed him Seashore (a first mix at the time). >.> Yep, he tried to push me into a different direction than I wanted to go into. And against what I wanted to do- because I really wanted to learn composition- I dropped it. Since my only strength as a complete newb in a college music world was my ability to write music, I couldn't risk compromising becoming uninspired and frustrated.
I will definitely look up those artists! Thanks a lot!
