The violin (etymology: the violino Italian, diminutive of viola or viella) is a bowed string instrument that has four strings. It is the smallest and acute family of classical string instruments, which includes the viola, cello and double bass, which, except for the bass, are all derived from the medieval violas, especially the fiddle. In ancient violins, strings were gut. Today they can also be metal or gut wound with aluminum, silver or steel; rope on me, the sharpest cantino- -called is directly a steel wire, and occasionally gold. Currently strings are being manufactured from synthetic materials that tend to gather the sound achieved by the flexibility of the casing and the resistance of metals. In addition to the effect achieved by the arc, you can get other effects: pizzicato (pinching the strings as if it were a guitar, but not with the same position), tremolo (moving the bow up and down very fast), vibrato (making vibrating fingers on the strings), glissando (left hand moving up and down on the strings), col legno (playing with the wooden part of the bow), sul ponticello (playing almost over the bridge). The sheet music for violin almost always used the treble clef, formerly called "treble clef".

The voice:  The piece rose to extreme popularity in the 16th century, even appearing at the head of the first volume of motets ever printed. Its revolutionary open style featuring early imitative counterpoint and two-voice parts has added to its acclaim as one of the most influential compositions of its era.
