hey peeps...

I am really interested in writing my own song, although most of the time I play along to green day, my chemical romance, fall out boy and guns n' roses...

so yeah...

i play bass and guitar just so u no..

I would be really grateful, from all of you that do write your own songs, if you could provide some tips...

thanks... :P
Yeah, Couldn't agree more really.. It is just a case really of saying whats on your mind or playing whats at your fingers.. Start writing some lyrics or just write a basic chord progression and see what words you can get to work over the top.. Theres no set way to do it, just od it however feels natural..
Learn theory, analyse some songs with theory, borrow a "melody writing" book from your local library, study counterpoint. Do this in this order.

How to actually write a song:
Write a singing melody
Write fitting lyrics
Write a guitar part
Have the drums/bass follow the guitar
