I wouldn’t be in a big rush for confession right now. It’s more important, in my opinion, to pray for guidance each step of the way. My first appointment with our just-too-fabulous-for-words priest was a little over a year ago and he told me what to expect, gave me a catechism (not the full catechism but the condensed narrative-style), gave me the papers I needed for my marriage nullification issue, blessed me and sent me on my merry way. After that it was only a matter of biding my time until RCIA began in September which seemed at that time to be a freaking eternity LOL. Oh, and the nullification issue was one of the easy ones (first husband had been married before me therefore had a prior bond, so the review only took five weeks). Every Sunday before RCIA it was agonizing to stay in my pew while most of the others went forward to receive communion, but looking back now it was good for me and will be soooooo worth the wait. As a note, during RCIA we are dismissed after the homily and go to the parish life center for Breaking Open the Word, a discussion period. Just three more loooooooong weeks and that will be over
I say all of that to say this - take your time, study, go to Mass as often as you can, go to Adoration if it’s available, and when it’s time for RCIA, you’ll be ready and will have a wonderful experience. Next thing you know, it will be Easter Vigil time and you’ll be HOME!
ETA: as for music, I struggle with the music at Mass, mainly because I am totally unfamiliar with most of it, and long for some good ol’ Southern gospel Bill Gaither style. I love to sing (it’s doubtful those around me enjoy hearing me) but most of the time I find myself just looking at the hymn and keeping silent. ~sigh~
