Elective classes in American Popular Music and World Music are a staple of our high school music curriculum. These classes are open to students in grade 9-12, and are ways for students that do not participate in traditional music ensembles to explore and expand their musicianship and creativity. iPad devices are the centerpieces of these courses, as they employ iPad devices and GarageBand to allow students to compose their own original songs. The Four C's are constantly applied by students in music classes. Students employ their skills in critical thinking, creativity, collaboration, and communication to make musical decisions such as instrumentation, form, balance, and communicating the meaning of songs through music.
