A Revolutionary Shoulder Rest for Violinists and Violists.

More Than a Shoulder Rest—A New Way to Play.

The ASR (Audio Shoulder Rest) is the first Bluetooth-enabled shoulder rest for violin and viola that combines audio streaming with haptic feedback.

It lets you feel rhythm and resonance through vibrations, helping you internalize timing, improve technique, and connect more deeply with your music. Whether you're a beginner or a pro, the ASR enhances practice and opens up new ways to explore sound—including pop, electronic, and beat-based styles.

Meet the ASR Beta

After years of research, design, and engineering, the ASR is nearing its final form. What you’re seeing here is the beta version—a fully functional prototype that showcases the core of what’s to come. Sign up below to be first in line for the limited presale.

Years in the Making. Ready for What’s Next.

  • Our core technology is protected by issued and pending patents, so what's unique about the ASR stays unique.

  • The ASR has been featured in major outlets including Electronic Sound Magazine, showcased at the prestigious Guthman Musical Instrument Competition, and highlighted in ASU Thrive Magazine for its originality and impact.

  • The ASR was developed at Arizona State University, one of the nation's leading innovation hubs. Years of research, engineering, and cross-disciplinary approaches shaped the foundation of the ASR's design.

  • The project received $30,000 in seed funding through ASU’s Lab to Launch Pitch Day, a program supported by donors who champion innovation within the Ira A. Fulton Schools of Engineering at ASU.

  • This isn’t just theory—the ASR has gone through multiple prototype cycles, each one tested, refined, and improved for real-world use and durability.
