Hello GT people!

So i've set myself a task in order to learn what chords live in the main keys.

The task is simple - Write a song in every key! This will encourage and force me to learn what's where (I, II, III etc) and how to change between all the chords whilst keeping it fun.

Thing is, I find that verses come easy but I hit a wall when it comes to writing a chorus. Any tips, ideas or videos with some instruction would be greatly appreciated.

I should also say thats its the lyrics of the chorus that I struggle with, if i could get the words to flow then ill just match the chords to the lyrics (not sure if thats right or wrong but its what i've been doing whilst messing about).

How to get it to be different but remain part of the theme??

I hope this all makes sense, im very new to theory so i've explained it best I can.

Thanks for reading and take care.
