The University of Chicago is home to eight student-run a cappella groups, several of which compete regularly at the International Championship of Collegiate A Cappella (ICCA). The school's two most prominent co-ed a cappella groups are Voices in Your Head, which competed at the ICCA finals in 2012, 2015, 2017, 2018, and 2022, as well as the Ransom Notes, which competed at the ICCA finals in 2021. Other successful a cappella groups on campus include the soprano-alto group Cadenza (formerly "Unaccompanied Women"), which is also the school's oldest established group, as well as the tenor-bass group Run For Cover, which performs in prolific events across the Midwest every year.[citation needed]
