Well, I'm making some songs. And I have difficulties with the chorus part. First off, any tips on how to make a chorus lol? well, i've wrote some, some are good etc. But some, I don't know how the singing part in it should be. So that's obviously the biggest problem, how do you come up with the singing in the chorus? I've heard there's somekind of technique you can do with your mouth trying to make up a chorus for example "Flaaaash beeefore my eyeeees" in Ride the Lightning by Metallica. That's just at example, do anyone know how?
And, if anyone had any tips in songwriting in general please tell me I'd appreciate it

Its just another section of a song, just put a riff that wont get boring there and write some lyrics, they dont have to be too special...at all.

something catchy doesnt have to rhyme but it sometimes helps
