I'm a highschool player and I recently picked up the soprano this summer and I practiced quite a bit at the beginning then stopped for awhile because of marching season, and now I am practicing it everyday. I started out using a Rousseau NC4 on my Custom EX but then I switched to a Selmer Concept because I was getting a better sound. I've been working on mouthpiece pitch exercises and long tones but the concept just keeps on wanting to play with wacky intonation even when tuning to A=440. So I just wanted to know if any of you guys think I should stick to the concept or if I should try out some new mouthpieces. Thanks!
