Page "Viola" Paragraph 4

More recent ( and more radically shaped ) innovations have addressed the ergonomic problems associated with playing the viola by making it shorter and lighter, while finding ways to keep the traditional sound.

These include the Otto Erdesz ' cutaway ' viola, which has one shoulder cut out to make shifting easier ; the ' Oak Leaf ' viola, which has two extra bouts ; viol-shaped violas such as Joseph Curtin's ' Evia ' model, which also utilizes a moveable neck and a maple-veneered carbon fibre back, to reduce weight: violas played in the same manner as cellos ( see vertical viola ); and the eye-catching " Dalí-esque " shapes of both Bernard Sabatier's violas in fractional sizes-which appear to have melted-and David Rivinus ' ' Pellegrina ' model violas.
