Chapter 6 of Performing Music Research sets out the characteristic features of research interviews, introducing four types of interview: open interviews, which often arise spontaneously or informally and which are largely unstructured or explore an overarching topic of interest; semi-structured interviews, an approach often taken in music research that relies on a predetermined yet flexible set of principal questions; structured interviews, which make use of fixed and unchangeable questions within an entirely predetermined format; and focus group interviews, which take place with groups of participants rather than individuals. The chapter addresses some of the challenges of using different types of interviews, presents ways to design and conduct interviews effectively, and considers ways to write about and report them.
