Something Else, by British composer Joanne Griffiths, has a gently meandering melody over an accompaniment of two patterns, two chords and two time signatures. A little quirky lilt changing from 3/4 to 4/4 time will keep your students counting.
Clocks by Joanne Griffiths has a contemporary feel with echoes of Philip Glass. Control, balance and concentration will be needed to maintain the 2 against 3 cross rhythms. Ideal for intermediates of all ages!
