Record your music. Use a computer program such as GarageBand from Macintosh to record your best tracks. You can also record in a studio, but that is usually expensive. Take the time to make each song as good as it can be. Your recordings will ultimately represent you in the next phases of promotion. Burn as many copies of your CD as you think you can pass on to others. You can always go back and burn more if there is high demand. Write out or print out a standard label for each CD that contains your name as well as a link to the website you are going to create.
Promote your music through various outlets. Create a website using free resources such as Myspace. Post information about your music online. You can list upcoming performance dates, upload streaming mp3s of your music and write a biography that tells visitors about what you do. It is also a good idea to print fliers to post around colleges, coffee houses, bars and major intersection where people will notice them. The flier should announce any upcoming shows and provide a link to your website.
Perform your music live as often as possible. Building a fan base often means you will need to take the stage to showcase your talent. Attract a local crowd at first, playing at venues such as bars, coffee shops and clubs. If your music catches on, book some shows in advance and take short road trips to nearby towns and cities to play at other venues. Take along your CDs to sell or give away to the crowd.
