Bon Musica 15.5" Viola Shoulder Rest
The Bon Musica 15.5" Viola Shoulder Rest is a German-made ergonomic accessory designed to provide customisable support for viola players. It features a flexible metal base that allows for precise contouring to the player's shoulder and a hook-over design that stabilises the instrument.

Overview
The Bon Musica 15.5" Viola Shoulder Rest is an adjustable support system developed for violists who require a higher degree of stability and customisation than standard wooden or plastic rests provide. Manufactured in Germany, the device is characterised by its distinctive 'hook' design, which secures the rest over the player's shoulder to prevent the instrument from sliding. It is specifically sized for violas measuring 15.5 inches at the lower bout mounting point.
Design and Key Features
The primary structural component of the Bon Musica rest is a flexible metal base. Unlike rigid rests, this metal plate can be physically bent and manipulated by the user to mirror the specific curvature of their collarbone and shoulder.
Key features include: * Customisable Contours: The metal plate retains its shape once bent, allowing for a bespoke fit. * Foam Padding: The contact surface is lined with thick foam rubber to ensure comfort during extended practice sessions or performances. * Adjustable Height and Tilt: The mounting feet can be adjusted to alter the height and angle at which the viola sits relative to the player's neck. * Stable Mounting: The feet are designed to grip the ribs of the viola securely without damaging the varnish.

Ergonomics and Player Utility
This shoulder rest is particularly noted for its ergonomic benefits. By allowing the player to mould the rest to their body, it reduces the need to 'hike' the shoulder or use excessive chin pressure to hold the instrument. This can be beneficial for players suffering from tension or those with unique physiological requirements. The manufacturer emphasizes that the product works flexibly around its owner, prioritising user comfort through its thick foam rubber padding.
Sizing and Fitment
Correct sizing is critical for the Bon Musica system to function as intended. Users are advised to measure their viola at the mounting point (the lower bout) to ensure the 15.5" model is appropriate for their specific instrument. While the metal base is flexible, the width of the mounting hardware is specific to the instrument's dimensions. Proper fitment ensures that the rest does not slip during play and that the weight of the viola is distributed evenly across the shoulder.
Comparison to Alternatives
Compared to standard rests like the Stentor Graduate or more minimalist designs, the Bon Musica offers significantly more surface area and physical support. While wooden rests may offer a more traditional aesthetic, the Bon Musica's metal construction provides a level of mechanical adjustability that is difficult to achieve with organic materials. It is often paired with high-quality components such as Goetz Kaufmann style chinrests or Wittner adjustable tailpieces to create a fully customised ergonomic setup for the violist.
