I am the singer for my band and I'm ok but I could do so much better if I found the vocal melody for a song so I know what it is and not just by ear... any place where I could get the melody for free cause I've tried google and all I can find are websites where I have to buy them
Vocal melodies are the easiest to figure out by ear, assuming they aren't in harmony with other vocals. Just do it by ear, you need the practice if you're asking this.
Some of the Powertabs or Guitar Pro tabs on this site have the vocal line. You're much better off learning by ear though, it gets better over time.
