Kelvin offers students an opportunity to perform on traditional band instruments in either the grade 9 concert band or the senior concert band. While the grade 9 band is scheduled in an option slot, the senior band meets outside of the timetable on Mondays, Wednesdays and Fridays. These ensembles perform at various times through the year and have a great deal of fun in the process.
For those students so inclined, there are also two jazz bands in which one can hone their musical skills. These ensembles also meet outside of the timetable. Students need to audition to be part of the jazz program, as space is limited.
