As you can see by the list of contents, there are some very famous tunes here and they're all arranged sympathetically for 4 flutes with an optional (separate) piano part. Hedwig's Theme is the easiest and would make a great introduction to ensemble playing for those first-timers. Pieces like The Magnificent Seven will cement syncopated rhythms and Pink Panther will help chromatic passagework. The parts are usually divided 3+1 or all 4 in rhythmic unison so there is scope for some independence for the slightly more adventurous. It would be really good if the parts were printed separately but that would send the cost rocketing. This is still worth investing in though - especially as you can also buy parts for other instruments.
