Q: I am currently planning a few evening prayer services at my parish in August, and have been reading in the GILH how music and hymns can be incorporated. Could you point me in the direction of any good resources the might expand on this topic?
A: For repertoire, many hymnals have sections devoted to hymns and psalms suitable for morning and evening prayer. They may even have an order of service in the introductory material.
There are apps that incorporate the words of hymns into the office as well.
