I have also used some of the Gustavson and Andr?s pieces, which I like. However, my
favorite lever harp piece with special effects is Kymation by Darhon Rees-Rohrbacher,
published by Dragonflower Music. It calls for tuning of F#, G#, A#, B#, C, D, and E natural,
so some re-tuning may be required, but it’s worth it. The special effects include glisses,
harmonics, pdlt, xylophonic sounds, nail glisses, tapping with fingers and knuckles, and a
whistle (quickly sliding your flattened hand up on the wire strings to create a whistle
effect). The students I’ve used it with have also enjoyed it. I would probably rate it
advanced-beginner or early intermediate (definitely easier than Andr?s’ Epices, for
instance).
