Help Kids Make Music
With Every Purchase

We donate 5% of our direct sales revenue from to the Sound Start Foundation, dedicated to donating 10,000 instruments to children across the world by the 2020-2021 school year. We’re excited to share that the Sound Start Foundation recently met that goal, and will be proposing an exciting new target shortly. Thank you for your support.

Studies show that playing musical instruments at a young age positively impacts overall performance in school and teaches valuable life skills. Unfortunately, arts programs are usually the first to be cut when districts face budget shortfalls. Sound Start helps ensure kids can still have access to musical instruments so they can realize their full potential.
