Every student at St. Pius X has a weekly music class. In the Pre-K and Kindergarten classes, students learn to feel the beat in music and sing tunefully through singing fun songs, playing rhythm instruments and moving to music. Academic concepts such as letters, numbers and colors are also reinforced. In the intermediate grades, the students begin to learn about how to read, write and sing from standard music notation. Third graders play the recorder, and fourth graders have a special emphasis on proper vocal production and performance. In middle school, the instruments of the orchestra, music history and introductory music theory are explored. An introduction to improvisation, music form and composition is given in a special blues songwriting activity. At all levels, the importance of music in the Catholic liturgy is emphasized through regular practice of songs for the Mass.

Beginning in the fourth grade, students can choose to participate in the St. Pius X Choir, which meets once a week after school. They have already given several performances this year and plan to participate in the district music festival in March. Students in the fourth grade and above may also join the school band, run by the Archdiocesan Band Program, which meets weekly during the school day.
