One of the challenges of having a children’s choir is funding it. You can teach for free and often find a practice place for free, but sheet music and other related materials are generally not free. Or your choir might not be a community volunteer endeavor: might need to earn a wage, and so you need to charge some kind of tuition.
Today I saw this and thought it was a new twist on funding a choir! It’s “pay what you can” tuition. Wow! Here’s the link to my friend’s choir and how they decided to fund their program this year: http://www.brownpapertickets.com/event/467233.
