Violin Shoulder Rest 3/4–4/4 Size | Adjustable Clamp, EVA Foam Pad

Symphonymuzik Violin Shoulder Rest – 3/4 & 4/4 Size

Designed for full and three-quarter size violins, this shoulder rest delivers ergonomic positional support and secure instrument stabilisation for intermediate and advanced players. The universal-fit clamp system accommodates both 3/4 and 4/4 violin bodies, making it suitable for older students, adult learners, and conservatoire-level players seeking a reliable, adjustable accessory.

Technical Specifications

• Compatible Sizes: 3/4 and 4/4 (full size) violins
• Frame Material: High-impact ABS plastic — lightweight, torsionally rigid, and resistant to deformation under sustained clamping pressure
• Padding Material: Closed-cell EVA (Ethylene-Vinyl Acetate) foam — provides consistent cushioning, moisture resistance, and long-term shape retention under daily practice conditions
• Clamp Mechanism: Dual adjustable clamps with multi-axis pivot — each foot independently adjustable to conform to varying shoulder contours and collarbone profiles
• Clamp Foot Material: Rubber-tipped contact points — prevents slippage on the violin bout and protects the instrument's varnish and finish
• Adjustment Range: Claw angle adjustable across approximately 30° of rotation per foot for precise ergonomic positioning
• Weight: Ultra-lightweight construction — negligible acoustic impact on instrument resonance and projection
• Finish: Smooth matte ABS body with contoured EVA pad surface for consistent shoulder contact

Design & Ergonomic Features

The shoulder rest's curved profile bridges the gap between the violin's lower bout and the player's shoulder, reducing neck and trapezius strain and enabling a more relaxed left-hand technique. The EVA foam pad distributes contact pressure evenly across the shoulder, preventing localised discomfort during extended practice sessions. The tool-free adjustable clamp geometry ensures a secure, rattle-free fit across the full range of compatible violin body widths.

Acoustic Considerations

The ABS frame and EVA pad combination is selected to minimise sympathetic vibration and unwanted damping of the violin top plate. Rubber-tipped clamp feet isolate the rest mechanically from the instrument body, preserving tonal clarity, sustain, and natural resonance characteristics.

Ideal For

• Students aged 10+ and adult players on 3/4 or 4/4 size violins
• Music schools and conservatoires sourcing student and intermediate-grade accessories
• Players transitioning from fractional to full-size instruments seeking ergonomic support
