Lela, the difference between our curriculum and others is that we use real staff right from the beginning. Mozart and Hayden were creating songs mostly for the 5 octave instruments. Later on the amount of keys increased.
Therefore, 5 octaves is the mast for our program and the keys supposed to be real in size.
You may download and learn Note Duration game, work with the cards and song on TRY NOW page, learn Hanon on your keyboard and spread the word about the program.
I promise you: if our committee will see the will, we'll find the way to help you!
