Edit: Wow this was longer than I thought. Sorry for the Paragraph xP Well I'm singing in a church for fun (I've only had a few lessons.) But one thing is still evading me. I can sing GREAT! when i'm singing along to someone else who is on key and sounds great such as listening to like Beyonce or Sam Smith on the radio but if I turn the music off I can't tell if I'm on key or not. Also if someone sings with me it throws me off because for some reason I can't sing by myself I have to match the person its almost subconscious. Like all four of us are singing. The key of the song is too low and I am awkwardly going between singing it low but (I can't sing low and loud) and singing the key high to match everyone. I am slowly getting somewhat better about this but harmonizing is still difficult. I can't listen to someone sing and just harmonize right off of them like other people can, because like I said, I have to sing along to them. Also, they cant harmonize to me because if I am singing low, and they start singing a higher key I naturally move up in the same key as them. I can't stop it either. I can somewhat alleviate it by covering my ear or ears and singing but it isn't sustainable. Any help would be greatly appreciated.
