Hello Songwriter Friend, If I may be honest here without hurting anyones feelings. I see it like this, If you were going to a job interveiw and there was another person also looking to be hired at the same time as you for the same position. The job called for lets say a waitress. You are a great waitress but so is the other person only thing she can cook too and sometimes the cook at the dinner stays home instead of going to work.
Well that other person has an advantage Waitress + Can cook... Hope you see what I'm Trying to say.
Go buy a nice keyboard. They are great today so easy to learn and play.
Create your melodies and then take your rough demo and get it produced by a pofessional
Demo up all you can. Main thing Promote your music.
No good if it sits somewhere and no one hears it. Get it heard , Out there
But all in all, A great set of lyrics can and do stand alone. Many hits are out there by someone who only wrote the lyrics.
Good Luck in all you do.
Hope This Helps you a little.
Your Friend In Music, Carmella
Who cares if a songwriter who does both looks over a person who doesn't do both. It really doesn't matter. All you have to do is find a person who complements your weakness and there ya go!! Me, I 95% of the time just write melodies. Julie handles the lyrics, 95% of the time, and it's a perfect match for us. Case in point, Remember Foster and Rice? Foster handled the lyrics, Rice handled the melody.
