I am 14 and I want to start a music career?

Geez - learn to write ENGLISH!!! If your post here show the organization and clarity of you music composition - you will never get anyone to listen to you. FIRST - you need a TON of music education - either private lessons on your main instrument and/or voice, OR in your case, music theory and composition. You cannot just *make up stuff* and then hope that you find *someplace* that will publish it. Not gonna happen. You are competing with people who have far more education than you, more talent than you, more contacts than you, more experience than you. WHO told you that you have talent and ability? Your friends? Gramma? Unless it came from an authorized source, like a certified multi-degreed teacher, or anyone else with a good education and credentials, and impartiality, then that opinion DOES NOT COUNT. And your own opinion of yourself does not count, either. You need serious assessment and then education from top professionals who have education and experience - and this is seldom the stoner at the local music store. THIS IS MY PASSION is not worth anything - you need something and MORE of it, that others do not have - and from what you wrote, I just do not see it. I have been a full-time professional musician and music educator since 1973 in NY, and have heard and judged thousands of EDUCATED students in competitions - and the whole attitude of "I am talented - publish my stuff!" is not going to work. If you compose in a digital format that can by copyrighted (you will need a lead sheet for copyright, so it HAS to be written) like Finale or Sibelius, then you can start by putting things up on their Users Groups on their websites. Nothing happens from YouTube - nobody cares - it's where people put pictures of their kittens. Only your friends see it, and they tell others - and it's not all complimentary, if you get my meaning.

Get an education - lose the attitude, because you are hurting yourself - and get some local live performing experience. If you survive and benefit, write back. Oh - and go see Llewyn Davis.

Start a musical career by treating it as a pastime or hobby, while completing an education that will make a living for you, much more likely doing something else. Feel free to do a search on the phrase "Starving Artist" for a little more perspective. OK, skip that - I forgot the bunch that use that handle as a sort of joke to sell stuff.

Start planning where you are going to college. Get your band started. Play everywhere that will let you play. After they start asking for you, then you can think about charging for you performances. If you can get a few hundred at each of your performances, then it is time to search for an agent, if one hasn't all ready found you. Keep writing your own music, but play and sing others as well.

Good luck
