Beauty is hard to make. X wrote those four notes in 1542 or 1979 or 1825 or whatever period you are worried about being influenced by. You have to say yes to what comes out. You can scoot it around a bit, but the basic material that jumps out of you is you. You are allowing others to tell you what real art is.
Real music soars above class society.
Musical careers have a lot to do with class and money, but they don't influence society's acceptance of the music, after the stuff has been broad-cast to the people. But doing those other activities does not make you a composer, though they may add to your career or savings account. Being a composer of playable music still does not guarantee beauty. That's a problem you have to solve for yourself. Beauty got a bad name some time after the first world war.
