Why is it when I use a major scale in my compositions, it sounds like a cheesy, nursery rhyme. Sounds really corny. If I transcribe a song composed by Burt Bacharach, he uses the major scale really well.

I think my problem is that I never have a good grasp of the major scale. I hear the major scale played up and down all the time, but I am not familiar with the major scale itself.

Is there a way to familiarize myself with the major scale or discover new variations of notes? I heard many composers totally rock the major scale, I want to end up like them.
