Though I'm no teacher, from my understanding, essential rep for a beginning student would include selections from:The Notebook for Anna Magdalena -- BachGerman Dances of Haydn and BeethovenAlbums for the Young -- Schumann and TchaikovskyProgressive Studies Op. 100 -- BurgmullerMinuets, Beginning Works, etc. (K1-K6) -- MozartThat's just a few. Hope this helps!
