The violin is the highest member of the string family, and often can be heard soaring over other instruments. Its tone is bright, but very flexible.
While some instruments lend themselves to few options, the violin marries itself to almost any style. Slow and mournful, bright and cheerful, classical, jazz, gypsy, klezmer, rock, pop, and fiddling only scratch the tip of the iceberg of the violins capabilities.
Most of the time, the violin holds the melody in orchestral and ensemble music. Violinists learn to lead other musicians. The repertoire written for violin is incredibly vast; a violinist would be hard-pressed to become bored with their selection.
