So we are working on a song in band class and I have a really complicated part on the tubular bells close to the end of the song. I realized that this song is in the same key as Snow Halation, so I thought that if I ever mess up or forget what I'm playing I can just play Snow Halation. So it comes to my part, and I'm gonna be honest I completely fumbled the first part, so I started playing Snow Halation. Well, I guess it fit in so well that my band teacher complemented me afterwords thinking that I had learned the part. Should I keep just playing Snow Halation or learn the part lmao?
