The serious use of mathematics by researchers in music theory has grown substantially since the work of David Lewin and others in the 1980s. One area of mathematical music theory that has undergone interesting development is voice leading: the particular ways that harmonic changes are realized through assignment of different pitch sequences to a collection of distinct "voices" (musical parts, melodic lines, etc.). I will give a brief survey of some of the ways voice leading has been modeled mathematically, ending with a case for using orbifold fundamental groups and groupoids of chord spaces that I made at the fifth biennial Mathematics and Computation in Music conference, held last June at Queen Mary University in London.
