Kusimama by Jim Papoulis is one of those choral pieces that is both challenging and really fun to sing.  I’ve had 5th graders at two different schools with various degrees of choral singing experience sing this piece very successfully and with great joy.  It is a great teaching piece and one that I love. It’s also a real crowd pleaser!  The piano part is basic enough that even I can play it when needed and the song is a perfect opportunity to incorporate percussion instruments.
