The song of Cinnamon Tanager is described as a series of sweet-sounding whistled phrases, composed of trisyllabic stanzas (Isler and Isler 1987) with some phrases repeated once or twice; for example, "wee-chur-chur, pur-tee, pur-tee, we-chur, we-tur-tur" (Hilty 2011). The song is typically delivered in the open from the tops of small trees (Isler and Isler 1987) and is generally four seconds in duration (Hilty 2011). It is similar to the song of Black-faced Tanager (Schistochlamys melanopis), the distribution of which overlaps that of Cinnamon Tanager (Isler and Isler 1987), and there is some geographical variation reported (Hilty 2011).
The call of Cinnamon Tanager is a low-pitched and hoarse "jreeet" (Hilty 2011). Additional audio recordings of vocalizations of the Cinnamon Tanager can be heard at Macaulay Library and at xeno-canto.
