Not only is this outstanding series of popular Christmas favorites appealing to students, it is the most pedagogically structured choice of teachers everywhere. Use the Primer Level for your beginner's first Christmas performance. Level 1 features easy piano arrangements using I, IV,Â and V7 chords in the keys of C, G, and F. Level 2 introduces more hand position movement. Sophisticated arrangements in a wider variety of keys are used in Levels 3 and 4. Each level is correlated with Bastien Piano Basics or any other method at a comparable level.
