Being in music forever, I have good pitch, so I know when I'm singing in or out of tune. But the key to really good singing is just relaxing and thinking about what the song is.
It's my job to try and be as good a person as I can, and that's enough work for me.
When I was playing piano, it was like, 'I'm going to write a song using all the white keys.' My music director, who knew my jazz background, suggested I try big-band music, so we spent a year experimenting with it in concert, and the audience reaction was really good.
It's impossible to be a good Christian. If you think it's easy to be a good Christian, then you're not really trying hard enough.
