About us

Keynote Pianoworks was started in 2021 by Mathias Walters, a lifelong pianist with 15 years of experience working with pianos. Based in North Charleston, South Carolina, Keynote Pianoworks is dedicated to providing complete service for pianos—from routine maintenance to complex repair and full-scale restoration.

Keynote Pianoworks strives for excellence in the art of piano technology. We are committed to preserving and reviving high-quality antique instruments. Whether working on-site through mobile service calls or in the Keynote Pianoworks workshop, we approach each project with a passion for music and a dedication to the craft.

In addition to our piano service offerings, Keynote Pianoworks is also developing a piano supply business to serve the industry through our sister business, Keynote&nbps;Piano Supply. We love to share our ideas and techniques with fellow piano technicians and enthusiasts. As the company continues to grow, this new supply venture will complement our current services.

While Keynote Pianoworks is a young business, the expertise and care that goes into every piano project is unmatched. The mission remains the same: to honor the art of music through the meticulous restoration and maintenance of cherished instruments, while also supporting the broader piano community.
