Consider the possibility of getting started with vocal music by trying to recruit (perhaps through one of the local music schools) a single enthusiastic talented soloist, soprano, alto, tenor, or bass, and invite him or her to (help) select from the very wide available repertory, those songs, Lieder, arias that she (or he) would like to perform with orchestral accompaniment. Such vocal performances might become a regular part of your programs. Your cooperative soloist could help you to recruit colleagues, and ultimately to organizse your own choral group.
