Here's a song I wrote for Chinese New Year- easy peasy! Simple level bordun for accompaniment- add unpitched percussion (UPP) for the percussion line- lots of gongs, drums, etc. to "scare away" evil spirits. Very nice with a big, low gong at the end. Good for your upper level recorder players, too- those who have a solid low "C".
Look on youtube for pronunciation guide - Xin = Shin, Nian= like it sounds, Kuai= kwahee, Le = luh Yi (number 1) = eee, Er (number 2)= are, San (number 3) = sahn, "Jia You" (Let's Go! as in cheering people on) = jya yo.
