The bass drum usually has a diameter of 50-100 cm and membranes on both ends of the cylindrical body. Although the drum does not have a well-defined pitch center, it is common practice to tune the lowest modes of the two heads about a musical fourth apart. The coupling between the two heads of the drum produces a splitting of the two lowest modes, the 0,1 and 1,1 modes. |
