The stable position of the teeth represents equilibrium of all the forces exerted by muscles of the tongue, buccinators complex. Myofunctional therapy may be aided by the use of tools that are not strictly Orthodontic such as a musical instrument. A musical instrument introduces a complex of new pressures which could be evaluated, measured, and understood. Strayer first recommended the use of specific instruments for their beneficial effects in certain malocclusions. He divided the wind instruments into four categories according to the type of mouthpiece used: 1. Class A- All cup-shaped mouthpieces, as in the trumpet, trombone, tuba, all horns, and brasses. 2. Class B - Single-reed mouthpieces, as in the clarinet and the saxophone. 3. Class C - Double-reed mouthpieces, as in the oboe and bassoon. 4. Class D - Mouthpieces with a small aperture or opening at the head, as in the flute and piccolo. Class A or cup-shaped mouthpieces have a tendency to reduce overjet and overbite. Class B or single-reed mouthpieces such as the clarinet or saxophone tend to increase overet and overbite. Class C or double-reed mouthpieces and Class D or aperture mouthpieces have a tendency to reduce overjet and increase overbite. Class 2 division 1 malocclusion with protruding upper incisors and hypotonicity of the facial musculature will be benefited by the use of class A instruments Therefore, Class A instruments can be helpful adjuncts in correcting Class 2 division 1 maloccclusion
