Good to hear you are in a writing mood. In my opinion playing covers is like an artist who just copies other people's paintings. When you paint your own paintings or write your own songs they may not be great but at least they are yours. In conversations with other writers I'm amazed how many different ways that song writing is approached. I'm the type that almost always starts with a hook and then develops lyrics to support the hook, all the time experimenting with different melodies and chord progression to support the storyline. Occasionally I'll start with some little guitar riff and build a song around it but in my case that is pretty rare.
I'm guessing that for every song I've written that I'm not ashamed to play in public, there is at least one that goes into a folder for a future re-write or into a "black hole" never to be seen again.. One of the best song writers I've met swears that the best songs come from re-writes, but unless I consider the song a "keeper" early on, I don't spend much time trying to refine it. For me the toughest part is trying to get rid of "extra" words that do not contribute new information in each verse. Nothing bugs me more than a song which drags on, essentially saying the same thing verse after verse. My goal is to someday write a song like "My Girl" - just 21 words or less in each verse and another 18 in the chorus, yet conveys a story and emotion.
I hope to hear some your song writing efforts sometime.
"If Einstein hadn't discovered the theory of relativity someone else would have because its a basic science truth. Same for Watson-Crick and DNA. But if Beethoven hadn't written "Moonlight Sonata", no one else would have. If Van Gogh hadn't painted Starry Night, no one else would have."
I don't want to play songs, I want to create songs.
