Dale Duncan is the creator of the S-Cubed Middle School Sight Singing Program. In the S-Cubed system, you get everything you'd receive in a sight singing book and more...thanks to modern technology. You get the sight singing examples, rhythm examples, bell-ringer activities and you also get direct links to video teaching tips and video teaching examples that take you directly into his classroom as he teaches his students. 10-15 minutes per day...fun approach. That's S-Cubed!
