Sonic Spaces of the Karoo is a pioneering study of the sacred music of three coloured (the apartheid designation for people "not white or native") people's church congregations in the rural town of Graaff-Reinet, South Africa. Jorritsma's fieldwork involves an investigation of the choruses, choir music, and hymns of the Karoo region to present a history of the people's traditional, religious, and cultural identity in song. This music is examined as part of a living archive preserved by the community in the face of a legacy of slavery and colonial as well as apartheid oppression.

Jorritsma's findings counteract a lingering stereotype that coloured music is inferior to European or African music and that coloured people should not or do not have a cultural identity. Sonic Spaces of the Karoo seeks to eradicate that bias and articulate a more legitimate place for these people in the contemporary landscape of South Africa.
