Following is a basic outline of the construction of a violin in the manner of the old masters.
Step 1: Obtain Aged Wood
Maple wood is typically used for the violin's back, ribs, and neck.
Spruce wood is used for the top or belly of the violin. Spruce is preferable for the top of the violin because it's a softer wood, so it vibrates more easily.
Wood should be aged by at least five years, but the greater the better. 20 years of aging is the most preferable, but that wood is more expensive.
