for SATB unaccompaniedWritten in an a cappella style with scat accompaniment, A Tree is a Song is a joyful celebration of the connections and affinity found in nature and how wisdom and knowledge can be passed on 'as a melody from tree to tree'. McDowall's setting of Heather Lane's text embodies the theme of connection as the parts imitate and respond to each other, sharing in the heartwood's song.
