"Theory Time is truly the standard for private music education. The techniques are unique, and have proven successful for years. As a former student of Heather Rathnau, I credit her Theory Time curriculum with the strong foundation for my formal music education and career. I highly recommend Theory Time to all private music educators."

"Theory Time® is just what the market needed! All of my school-age students are working through this comprehensive series. The user-friendly format introduces new concepts while continually reinforcing previous material. My students have a sound theory base thanks to Theory Time®!"

- Barbara Steiner, Minnetonka , Minnesota

The Theory Time® workbooks are thorough, yet fun and logical. My students and I share a greater sense of music literacy about structure as well as interpretation. It is particularly helpful for my high school students preparing to major in music."

- Marguerite Bostonia, Morgantown , West Virginia

"Theory Time® games are an excellent way to help children learn and review rhythm, notes and terms. Our group piano classes have so much fun, they don't realize they are learning! We have particularly enjoyed 'Wacky Eighths' and 'Symbol Clash.' The Theory Time® Reproducible Curriculums are also a strong addition to our program. We individualize the material we present to each student and this results in a cost savings to parents. The packets are well-written, easily understood, and the children enjoy working with them. Thanks for making these great tools available!"

- Ada Winters, President Piano Prelude Inc., Raleigh , North Carolina

"What a fun addition to any music method. My students love it and are learning more theory than ever before!"

- Jill Kitzmiller, NCTM, Kingwood, Texas
