Bon Musica 16.5" Viola Shoulder Rest
The Bon Musica 16.5" Viola Shoulder Rest is a German-designed ergonomic accessory specifically engineered for large-bodied violas. It features a unique flexible metal base and thick foam rubber padding, allowing the player to customise the fit to their individual physical requirements.

Background and Design
Designed in Germany, the Bon Musica shoulder rest represents a departure from traditional rigid wooden or plastic designs. It was developed to address the specific ergonomic challenges faced by violists, particularly those playing larger 16.5-inch instruments. The primary innovation of the Bon Musica is its customisability, moving away from a 'one size fits all' approach to a system that can be physically reshaped by the user.
Construction and Key Features
The foundation of the rest is a flexible metal base that can be bent to follow the exact contour of the player's shoulder. This allows for a more secure and stable grip compared to standard rests. The contact surface is lined with thick foam rubber padding, which serves to alleviate pressure points and enhance comfort during extended playing sessions. Users are advised to measure their viola at the mounting point to ensure the 16.5" model is the correct fit for their specific instrument dimensions.

Ergonomics and Playability
The Bon Musica is known for its high level of stability. Because the metal base can be curved over the shoulder, it prevents the instrument from sliding, which can reduce the amount of effort the player needs to exert with their left hand and chin. This ergonomic focus aims to promote a more relaxed posture, which is critical for preventing repetitive strain injuries in violists who handle the extra weight and size of a 16.5-inch frame.
Comparison to Alternatives
Compared to standard student models or rigid accessories like the Conrad Goetz Stuber or Kaufmann style chinrests, the Bon Musica offers significantly more structural customisation. While traditional rests might rely on height adjustment alone, the Bon Musica allows for lateral and contour adjustments. It occupies a premium price point (typically around £68), reflecting its specialised construction compared to basic plastic alternatives or universal accessories like Hidersine carbon bows or Wittner adjustable tailpieces.

Frequently asked questions
- What instrument is the Bon Musica 16.5" shoulder rest designed for?
- It is specifically designed for 16.5-inch violas. Users should measure their instrument at the mounting point before purchasing to ensure a proper fit.
- Where is the Bon Musica shoulder rest manufactured?
- The product features a unique ergonomic style that is designed in Germany. It is known for its high-quality engineering and flexible construction.
- What materials are used in the construction of this rest?
- The rest is constructed from a flexible metal base and is lined with thick foam rubber padding. The metal allows for shaping, while the foam provides comfort.
- Can the shape of the Bon Musica shoulder rest be changed?
- Yes, the flexible metal base allows the user to manually adjust and bend the shape to suit their specific shoulder contour and needs. This makes it one of the most adjustable rests on the market.
- How does the padding compare to other shoulder rests?
- The Bon Musica features thick foam rubber padding. This is designed to be more comfortable than thinner alternatives during long periods of use.
- What is the typical price range for this model in the UK?
- The typical price for the Bon Musica 16.5" Viola Shoulder Rest is approximately £68.00. This places it in the premium tier of viola accessories.
- Is this shoulder rest suitable for electric violins?
- This specific model is sized for a 16.5" viola. While brands like G4M produce electric violins (such as the Solus), the Bon Musica must be matched to the instrument's width at the mounting point.
- How does this rest stay on the viola?
- The rest uses a mounting system that attaches to the lower bouts of the viola. It is designed to work flexibly around the owner's instrument for a secure fit.
- Does this shoulder rest help with instrument stability?
- Yes, the unique ergonomic style and flexible base are designed to provide a secure grip on the shoulder. This helps the viola stay in place without the player having to grip too tightly.
- Can I use this 16.5" rest on a 3/4 size violin?
- No, this model is specifically for a large viola. Smaller instruments, such as a Stentor Messina 3/4 violin, would require a much smaller, dedicated violin shoulder rest.
- How does the Bon Musica differ from a Wittner tailpiece?
- The Bon Musica is a shoulder rest meant for ergonomic support against the body. A Wittner tailpiece is a mechanical component used for tuning and string anchoring on the instrument itself.
- What is the primary benefit of the 'hook' design on the Bon Musica?
- The flexible metal can be bent into a hook shape that goes over the shoulder. This provides extra stability and prevents the viola from sliding forward or down.
