After finding the main grammatical or stylistic error, the correct paragraph will be as follows:
Learning to play an instrument can be rewarding and life-altering. The joy a pianist receives when accompanying a choir of singers can make her years of practice and lessons all worthwhile. A flute that is played in a marching band will always make the flutist feel like she is a small but important part of a fun parade. Colleges pursue excellent musicians, and they offer a compelling scholarship if the student commits to performing in the college's marching band or symphony orchestra. Colleges need to lower tuition costs. These scholarships can allow students to attend college on a budget and pave the way for a bright future. Success should be expected by diligent and focused musicians; that's the truth of the matter!
