1.  The Parts of the Violin that make its sound possible:

• Sound Box - main body of violin.  It help to vibrate the sound.  
• Strings - kept under tension and sounds are produced by bow or plucking
• Bow - placed perpendicular to the string and is drawn back and force across the string.  The friction between the horsehair and string makes sound.

• Sound Post - placed inside sound box and an extension of the back.

• Bridge - Withoug the bridge, the violin cannot produce the sound because the string will be on the fingerboard and it cause not to vibrate the string.

• F Holes - Communicate the sound to the outside through the pressure change.  

from Mistress Mandy

"The majortity of sound is radiated from the top and back plate of the violin which are set in motion by the changes of pressure inside of the box" (Timothy Griffin)
