The Sound Devices hierarchy contains descriptors for devices used to produce sound, whether musical or nonmusical. This includes instruments played in musical performance, those sounded in the context of religious or other ceremonial occasions, sound producers that are not primarily musical instruments but serve to signal or communicate, and implements used with instruments to produce sounds. Relation to Other Hierarchies: Descriptors for sound pitch attributes (e.g., "soprano", "bass") are found in the Design Attributes hierarchy. Descriptors for devices that produce sound but which constitute integral building systems (e.g.g., "burglar alarms", "intercom systems") are found in the Built Works Components hierarchy. Descriptors for parts of sound devices (e.g.g., "resonators", "mouthpieces") and for implements used to set the sound-producing mechanism of a device into operation (e.g., "plectra") are found in the Object Components hierarchy.
