In my Church, we often have some lines sung by men, others by women, and others by both together.
Is it possible to change the colour of the lines to help those not familiar with the hymn (eg male - blue, female - red, both-together - green)?
At present I watch one of the members of the congregation whose neck colours red when he sings; but now that I have responsibilities to operate Zionworx that would prove more difficult.
yours sincerely
