What we do Courses FAQ COURSES: Do I have to attend both courses? Although we'd love it if you could attend both the Spring and Summer Courses to get the most from your NYCGB membership, we realise that sometimes you're not able to do so. However, we ask that you don't miss two consecutive courses as we need to hear all members regularly to ensure the high standard of our choirs. For example, if you miss the Summer Course one year, you need to attend in Spring the following year to retain your membership. As we don't insist that all members attend both courses, the number of members within a choir is greater than the number of places available on each course, so they do sometimes fill up. We always recommend that you don't delay and book your places as soon as possible!
