From the first model, violin history was made. It was so successful that violin makers from Gasparo de Salo, Guiseppe, Guarneri, Giovanni Maggini, Jacob Stainer, and the renowned Antonio Stradivari produced some of the world’s greatest violins. Made primarily out of maple or spruce, a violin is a hollow instrument with a long neck and four perfectly tuned strings. It belongs to the violin family of instruments that consist of the viola, the bass viol and the cello. It has several parts consisting of a bridge, sound post, peg box, fingerboard, shin rest, bass bar, tailpiece, back, and sound holes. Violins are classified according to electric, non-electric and two-acoustic.
