Abstract
Heuristic investigation, one of the lesser-known qualitative research methods in Brazil, is presented as a phenomenological research design in an empirical study investigating the experience of singing. This article describes the six phases of the heuristic method: initial engagement, immersion, incubation, illumination, explication, and creative synthesis. The method was developed by Clark Moustakas (1923-2012), an American clinical psychologist who, together with other renowned scholars such as Carl R. Rogers and Abraham H. Maslow, also contributed to the birth of Humanistic Psychology. The heuristic inquiry is a unique method in which the lived experience of the researcher becomes the main focus of the study, and it is used as an instrument in the process of understanding a given phenomenon. This method recognizes the importance of intuition and tacit knowledge as elements that enable comprehending a phenomenon and its meanings.
