The purpose of this action research was to determine if there is a connection between reading fluency and sight-reading music in a music performance group. Students were given a sight-reading test during their first and second years in band. They also took the Minnesota Comprehension Assessment test in reading during their 5th and 6th grade years. Data collection was obtained using the test scores from students who participated in a musical group (band, choir, orchestra) and students who did not participate in a musical group. Findings indicated that students who participate in a musical group (band, choir, orchestra) have a greater increase in reading test scores than those who do not participate in a musical group.
