shield secured over said head and comprising a sound box having an opening of gradually decreasing width and a horn-like hood of correspondingly increasing width over said opening.

2. An accordion comprising a valve head, a

shield secured over said head and. comprising a sound box having an opening of gradually decreasing. width from the lower to the higher pitched reeds, and a horn-like hood of correspondingly increasing width over said opening.

3. An accordion or the like comprising a valve head, and tone modulating means mounted over said head and providing increased deflection of sound waves from the lower to the higher pitched Q reeds, and a horn-like hood mounted over said means.

4. An instrument of the accordion type having a valve head, a sound box mounted on said head and having a horn and also having a substantially unobstructed tone passage arranged to divert vibrant air from said head away from said horn.

5. An accordion or the like comprising a' valve head, a sound box mounted over said head and having a horn, and means for varying the volume of sound emitted from said horn.

6.
