When you purchase the S-Cubed Sight Singing Program for Beginners Mega Bundle, you get the entire system. This program will take a minimum of two years to complete for most teachers if you spend the recommended 10-15 minutes daily three to four times per week. Watch your students go from not being able to sight-read at all to three-part SAB a cappella sight singing with a very high degree of difficulty in both rhythm and pitch as they work through the system. Students will also be able to take chromatics off the page and sing them a cappella with complete accuracy. Previous purchasers may download the latest version for free.
