Cytomegalovirus (CMV) is a prevalent pathogen, with 40 to 100 percent of the general population showing prior exposure by serology.1 Up to 20 percent of children in the United States will have contracted CMV before puberty.
The concept of the Sousaphone was created by the American composer and bandmaster John Philip Sousa, putting it in a category with the Wagner tubaâa horn conceptualized by German composer Richard Wagnerâand the Saxophone, one of the numerous inventions of Belgian instrument maker Adolphe Sax.
Most marching bands opt for the sousaphone, an instrument that is easier to carry and almost always cheaper than a true marching tuba. The earlier Helicon is still used by bands in Europe and other parts of the world. Drum and bugle corps players, however, generally use marching tubas or Contrabass bugles.
