So I have been playing for a year now I spent all my time learning theory and practicing on my technique and now I have joined a band and need to make the guitar parts for songs of my own. My problem is I just can't think of what to do like what to play for the verse, chorus, and bridge. I am just lost can anyone give me advice. BTW I wanna play 90's style alternative.
Learn and analyse songs in the style that you want to write. This should get you started.
also be patient
doodle around on the guitar. different emotions are also displayed in the music so if your sad and play you could get something like that.
