On Saturday N. played in a local festival celebrating Chopin's birthday. Over the course of five hours, local students, teachers, and professional pianists played works from Chopin's oeuvre. N. played a mazurka. Piano can be somewhat more isolating than other instruments children learn; there are rarely spaces for pianists in youth orchestras or school bands. So it is nice to have a chance to join a larger community of pianists. And in this case, it was especially fun for N. to participate in an event celebrating one of his favorite composers. He really enjoyed hearing so many different pianists interpret Chopin's music.
(The jumbotron directly behind N. was amusing to us.)
