My son, the drummer boy, played at his first concert ever – and proud mum can assure you he did well together with all the others. They gave the rhythm and led the singing to Brother John in seven languages. It was, however, a Christmas concert were a number of children and youth from the same music school performed and accompanied Christmas carols.
It was a cute way to get to sing Christmas carols together but it was a good way for the children to be introduced to various instruments. All music schools here have occasionally free concerts were their students perform, and everyone can walk in and listen for free. My daughter seemed very interested in one of the ones you can blow in (if she wants a trumpet, I’m not sure I can be supportive…).
Most churches will also organise a time to sing the most beautiful Christmas carols together. We to one of the churches to sing Christmas carols last year, my daughter loved it. Please find the times and churches in Helsinki here, still a few chances to go!
