I'm not musical. The last thing I thought I would be able to do was sing in tune. But here I am three months later and I can carry a tune, manipulate it and even harmonize with my children. Thank you David

You have inspired me to continue my music career. I can't thank you enough.

David has inspired two of my children to develop a deep and abiding relationship to music, and has helped bring much richness to their lives. My younger child could barely sing, and now he's playing and composing at an unbelievable level. I am very grateful.

After ten years of playing proffesionally I was frustrated I couldn't compose a piece of my own. The Science of Music approach changed my view of music entirely. I now regularly compose my own pieces.

Shabbos zmiros has become my favorite part of the week. I can harmonize and improvise on the spot.
