My 6 years old son started taking lesson two months ago. This week, one of his homework is to think and try to play "Tom Cat Howl" (PA T&A level 1) mysteriously as written (he already can play notes and rhythm correctly). Could you give me some pointer on helping my son understand and be able to play mysteriously? I don't have much music background, I would think that a cat walking at night (left hand staccato?) should be played very softly, but I can't think of it to be mysterious. Thanks!
