Thanks everyone. My main issue with chord theory is knowing how to combine chords an scales with a melody. I took a class in college on lyrics writting, where I learned about various lyrical writting methods. However, I am not a singer, and therefore I prefer to write instrumental songs. I guess I should have clarified that my song writing style is really more on the composition side rather then the traditional singer-songwriter side.
No worries
Here's the REALLY good news...your question started a whole knew part to the forum! How cool is that? So, great job!
Now, here is my take, don't be afraid to start with some short melodies, post them here, and ask! You will find that not only will you get suggestions, but explanations as to why! It's a FANTASTIC learning environment!
Don't be afraid to make "mistakes!"
