The purpose of this study was to examine participants' (college band and choral musicians, N = 143) perceptions of conductor clarity and expressivity after viewing band and choral directors conducting with or without a baton. One band and one choral conductor each prepared and conducted two excerpts of Guy Forbes's "O Nata Lux", a piece written in both choral and band idioms, with and without a baton. Participants viewed 10 excerpts (four choral, four band, and two distractors) and rated the conductors' clarity and expressivity on 10-point Likert-type scales. There were significant main effects for participant ensemble emphasis (choral or band), baton use, and conductor type (choral or band), and a significant interaction between conductor type and baton use. The choral conductor was perceived to be clearer without a baton, whereas the band conductor was perceived to be clearer with a baton. The choral conductor was perceived to be more expressive with a baton, and the band conductor was perceived to be more expressive without a baton.
