Nearly every part vibrates, or should vibrate depending on the quality of your instrument. The vibration passes from the string to the bridge to the face and then through to the sides and back of your instrument. Most of the sound you hear comes from the face and back of the instrument. That is why electric instruments such as electric violins and electric Guitars are so quiet; their bodies are not designed to absorb the vibrations from the strings. struck, hit, scraped

The sound is created by air passing through pipes. There are two main classes of organ pipes; flue pipes and reed pipes. Flue pipes are like whistles. There are no moving parts. There are both open and closed (stopped) flue pipes. Reed pipes produce their sound with a thin brass tongue that vibrates against a tube with a closed end called a shallot. This is attached to a larger pipe called a resonator. Depending on the shape of the pipe and the metal combinations used during the manufacturing of the organ pipe, various types of sound will be heard. Each pipe is tuned to a certain pitch ... middle A for instance is tuned (under ideal conditions) to 440 Hz, or 440 cycles per second.
