Create a stand-out stage name and develop your image and style to get noticed in the rap world. Your persona is not just about the stage name, although that's a vital part of your image. Envision the person you want to be, including mannerisms and personality traits. Exude confidence and originality; stand out. Make your presence felt by fans and music industry professionals alike.
Self-promote yourself and your music. Get your name out there. The Internet is a great tool for free or inexpensive promotion. Become part of the online community of rappers and hip hop artists. Create a website or make a MySpace page where you can feature your music. Add your link to online communities, such as Rappers Resource or Rap Space. The more exposure you can get, the better. Make an amateur music video and post it on YouTube and perform live whenever you can get onstage.
Practice your art regularly, alone and in front of an audience. No matter how confident, good looking, or persevering you are, you aren't going to get noticed in the music industry unless you can offer something new and something good. Accept criticism gracefully from friends and family.
You can record professional sounding music using downloadable software at home. Record and rerecord until you think you've done your best, then make it sound as good as you possibly can. Add beats to your vocals if you haven't already. Recruit someone who produces beats if you don't do that yourself. Submit your demo to websites like A&R Music Live or Killer Hype.
