There are many parts to a violin, viola, and cello, and these diagrams show the basic parts and names of areas on the stringed instrument shown.  The interior of the instrument also contains a sound post, bass bar, corner blocks, end block, and neck block, as well as the linings throughout.  The top of each instrument is made of spruce, and the rest from maple.  Purfling is found on the edges of the top and back, and is inlaid ebony.
