Very good taste.
MacDowell is a bit more romantically direct. Once, he was about to throw one in the fireplace and his wife rescued it. I think it was 'to a Wild Rose.' Overplayed, i know - but it's got charm.
How about Leroy Anderson? I think he was fairly genius, myself - but it's probably more jazz than classical. You know - the syncopated clock and all.
Didn't Tchaikovsky write a bunch of miniatures - i think i printed some off pianostreet a while back. And, Rimsky-Korsakov - did he? To me, the fantabulous miniature in larger framework would be Pictures at An Exhibition by Mussorgsky. That is the greatest of all time!
Right now, am using Saint-saen's Carnaval of the Animals for one student and they are very effective to use with younger children because they are short and sweet.
'Caprise Viennois' - by Fritz Kreisler. Suppose that many others are for violin and cello, too. But, they can always be rearranged for piano. Didn't Offenbach write some good stuff?
