Research indicates students who engage in music exhibit improved cognitive development. The quantitative study was conducted in a large suburban school district in Southeast Georgia. This study investigated the impact of music on student achievement when music is incorporated with the core academic subject of mathematics at the elementary level. This goal was accomplished by using a pretest-posttest control group design with a population of 51 third grade students and 51 fifth grade students through a series of analysis of covariance tests (ANCOVA). The t-test results showed statistically significant difference when comparing the experimental and control groups: t (26) = 6.11, p less than 0.000, t(23) = 3.73, p less than 0.001, t(26) = 6.01, p less than 0.000, t(23) = 7.30, p less than 0.000. Analysis of Covariance (ANCOVA) was used with the data to answer Research Question 2. Both groups showed significant difference. White students in both the control and experimental group outperformed black students in the experimental and control groups, F (7, 94) = 5.47, p less than 0.000. In answer to Research Question 3, when comparing the high socioeconomic group to the low socioeconomic group we find that many of the low socioeconomic groups scored higher than the high socioeconomic status groups F(7,94) = 6.03, p less than 0.000. It is recommended that future studies incorporate a power analysis to ensure sufficient sample size. The findings benefit teachers and students by presenting data supporting how the use of baroque and classical music playing along with music integration into the math curriculum is an important role in increasing student achievement in mathematics.
