i simply adore well done 'children's pieces' that really don't have to be for children, but are made such that little hands can play them. doesn't mean they have to be any less lovely, these two are two beautiful little gems. these are from a collection of works by Takatomi Nobunaga where each piece has intervals in each hand of a 7th or less....lovely little work. reminds me of Akira Yuyama's similarly styled book but these have a different feel to them, no less 'magical', no need to talk down to them just because they are young...
there was i believe at one point a solo transcription of the Bizet set that is originally for two pianists.
those are a joy to listen to. I don't know the specifics of the solo score or how to get it, been meaning to dig around for that....
