The Bon Musica Shoulder Rest features a Hooked Section which grabs the Shoulder and prevents the instrument from sliding forward.
The Bon Musica Shoulder Rest Hooked Section rests easily on the player's Shoulder, for an All-Round Comfortable Playing Experience. Comfort in playing is vital to all performers, no matter to which standard they are playing.
The Bon Musica Shoulder Rest Hooked Section is of the utmost importance to the Shoulder Rest.
It is Much More Convenient, (And Much Cheaper!) to have the ability to buy spare parts, rather than having to replace the whole Shoulder Rest in the unlikely event that your original Bon Musica Shoulder Rest Hooked Section should come loose and be lost.
