Toreador piano sheet music - these famous opera music arrangements are full of chords and scales, but are MUCH EASIER than they sound.
The little grace notes may be brand new to your students. One of my young pianists just could not "hear" the way it was supposed to sound, and needed much repetition at her lesson to cement that figure in.
Things fit nicely into the hand in this key... and the patterns on page 2 are not so difficult.
