One of the best ways to learn, improve, contribute, and be creative is to enter your music in contests. Usually, there are contests through magazines, online music forums, SoundCloud, and other media formats. I would urge you to look up some of them before you enter the contests. Be sure they are appropriate for your genre of music.
TIPS WHEN ENTERING A CONTEST
~Read the rules! I can’t stress this enough read the rules and then follow them. The worst thing you could do is win a contest only to be disqualified because you didn’t follow the rules correctly. If you have a question, don’t hesitate to ask for clarification. Remember, the goal is to get your music out there, connect with others, and learn more about music in general (others’ music and your own).
~Don’t submit a work longer than 4 minutes unless the competition specifically asks you to. Long songs are a sure way to bore even the most die-hard music enthusiast and will probably tire out the judges and those that will have to listen to your music.
~Always remember that competitions are NOT only about winning, despite what others might say. Contests are about people getting together to share their passions. They are about learning how to take your music to the next level. If you win, great. But if you lose, you still win. Those that enter competitions merely for the sake of winning are the ones that are failing. Those that get the most out of the competitions are those that open themselves up to the process and learn from the experience. Winning a song contest provides more than prizes. It can be a great intro to the music industry. Some have thousands of entrants, some have few. Some are better than others.
