I wanted to sing a song for my auditions that wasn't out there so that I can make it my style of music, sense my music teacher is always pestering to make music my own. Can anyone make up a good song for me to sing or list some songs that can be fitted for different song styles?

I have a week or two until my chorus audition. Any good, meaningful songs that will put me through? (Soprano/auto.)

This is the best you can DO! who knows were it will take you? The opportunities, people you will meet, new hobbies you will take. Acting is such a universal art like music. Trust me im a 22 years old and ive done filmmaking and music and being in drama and theater is the best by far. I say go for it and keep a smile on your face don't let people see you frown. Who knows you might like acting and then you can start up your own Youtube channel and write your own skits and make money of Youtube so many actors are doing this and its not to late for you to jump on the wagon NOW! so take my advice and do it!

You have to actually become an actor before you think about moving anywhere and looking for auditions!
It's not nearly as easy as you think.

Actors get auditions through their agents.
Agents will only sign real actors - those who have amazing resumes, showing many years of really good training at good acting schools and loads of stage and film experience. They are never, ever interested in beginners.
You can't just turn up to an audition - you have to get invited.

Yes - you do see a lot of 'new' actors in movies, but 'new' doesn't mean that they're beginners. It just means that they're not yet well-known. They've been studying acting for many years, usually at degree level, performing on stage in plays, taking tiny roles in small productions - and only get a good role after many, many years of struggle.

If you want to be an actor, get into a good stage school and start learning. But you really have to be realistic - it's going to take years of very hard work, and you'll only get anywhere if you have huge talent and loads of luck.

Why don't you start looking online or in the newspaper/magazine for maybe some recreational acting classes/groups. Maybe at a nearby college, you can ask the teacher if you could shadow him for a couple of days and see how the acting classes are~ That you're interested in it, but you're not sure where to start. Take the drama elective in school/highschool. Watch some youtube videos to get some general tips/ideas~
