MUSICAL INSTRUMENTS; ACOUSTICS

Note(s) This class covers generally all sound-emitting devices, whether or not they may be considered as being musical. The term "musical instrument", used in this class, should not be understood as excluding devices emitting a single sound signal. For the convenience of users, the following Class Index is given in place of Sub-class Indexes, to show the grouping of the elaborations belonging to different sub-classes, under the three fundamental types: Wind instruments String instruments Percussion instruments which relate clearly to the majority of instruments. There are of course some instruments of which the principle of operation belongs less clearly to one of these three types. They correspond to groups Fulltext... Hierarchy...
