Sources vary on the materials used to create the Portrait of a Musician. The Pinacoteca Ambrosiana (Archived 2 October 2020 at the Wayback Machine) and Zöllner (2019, p. 225) list the work as "tempera and oil", while Marani (2003, p. 339), Syson et al. (2011, p. 95) and Fiorio (2014, p. 153) list only oils, as do older sources such as Ottino della Chiesa (1967, p. 100) and Wasserman (1975, p. 138). None of these sources note any disagreement between scholars on the painting's materials. Zöllner, Frank (2019) [2003]. Leonardo da Vinci: The Complete Paintings and Drawings (Anniversary ed.).
