It's important to stay visible. You need to sing anywhere you can, as often as you can. Look for talent shows and singing competitions. Consider auditioning for "American Idol." Look for local clubs where you can sing and record some of the performances. Sing in church or at fairs. You never know when someone from a touring band might be in the audience and ask you to open a local show. The fact is, anyone could be in your audience anytime. Sing as often as you can, as good as you can.
Record a demo featuring five or six songs that demonstrate your vocal range. If possible, record the demo at a professionally equipped recording studio. If one isn't available, you can record a demo in a home studio. The demo is your calling card. It's what you will use when you look for an agent. If you write your own songs, so much the better. If not, choose songs that best showcase your vocal talents.
It's true, an agent gets a percentage of what you make--typically 10 to 15 percent. It's worth it. Agents have connections that you don't. The money you pay them is worth it. You can consult online databases for agent listings (see Resources) or check the labels of your favorite performers for information regarding the companies that manage them.
Record a CD you can sell at any of your shows. Make shirts, buttons and hats. Anything you can do to build a local following will help further your career. Get record company information from your favorite artist's CDs and send a copy of your demo to the record company. There's no guarantee it will be heard, but it's better there than in your bedroom. The only real way to make it big is to work hard and to continually promote yourself.
