Oh, thank you for the tips!

Also don't forget to sing in the car and practice changing pitch slowly so that you can learn to accurately land on the correct pitch without having to hear it. Practice singing what you're going to record so that you are prepared so you don't have to do too many takes, which gets really annoying.
Even if you don't sing now, learning to sing is a great, intuitive way to remember musical ideas. Record them on your phone to remember your ideas.
Oh yeah I've been slowly practicing singing for a long time now. This year I've actually joined a choir so I think I'm definitely improving much more lately (and if I had a bit more time, I feel would've been able to show this improvement more in this jam, but I barely had time to practice these harmonies and to record them).
Anyway, noted!
