I'm a guitarist and also lead singer. the problem is my voice thinks like a guitar, so i tend on repeating the melody line in my vocals, which is not what i want to do, but the thing is that on this one song the guitar melody is so hooky that i can't get it out of my head, and when i sing it sounds exactly like it. But i can't use the guitar melody for the vocal melody because it doesn't sound right what should i do?
