This shoulder rest is height, width, and curve adjustable so that the player may obtain a more comfortable and precise fit. The padded base is curved and can be easily manipulated to fit the exact contour of the violinist's shoulder, enhancing stability when shifting and applying vibrato. The foam padding is comfortable and quite durable. Unlike many other shoulder rests, the Bonmusica can easily be used for left-handed players. This popular shoulder rest aids players who suffer from previous injuries or arthritis as it allows the shoulder to remain relaxed while keeping the instrument at the proper height and angle, rather than drooping forward. All Bonmusica shoulder rests are German-designed and German-made.
