This is one of my favourite marimba compositions on offer here. It was inspired by a student who was proficient on drums but just starting out on 4-mallets. As the piece is only comprised of double vertical strokes, one can focus on the skill of small interval changes while keeping to the established polyrhythmic groove. The rhythmic patterns can be perfected on drums away from the 4.3 octave marimba before tackling the chord changes at the keyboard.
