Following period practices, most baroque violinists use gut strings. This lends a certain purity and even at times earthiness to the sound. Baroque violinists commonly play their instruments without a chin rest or shoulder rest, as they had not yet been invented in the baroque period. The relaxed and natural baroque violin posture is quite different as compared with the more poised modern violin position. The baroque violin is usually positioned more in front of the player than the modern violin, with the strings often running perpendicular to the player's collarbone. This causes the player's bow arm to be positioned differently as well, facilitating articulations which would be difficult and less natural in a modern violin posture. Some players do not touch their chin to the instrument at all. However, when used, the player's chin is usually placed on the treble side of the tailpiece.
Other typical differences from the modern violin include: a smaller bass bar, a differently shaped bridge which is thinner at the base and thicker at the top, a shorter fingerboard, a fuller neck, and the absence of fine tuners. The biggest difference between the modern and baroque violins is the tension of the strings and the pressure on the bridge. Most old Masterviolins have had new necks fitted - transplanting the original headstocks - that were slanted backwards so the strings would make a more acute angle on the bridge. Baroque violins have their necks in line with the underside of the plate the necessary upward angle is achieved by a wedge-shaped raiser under the fingerboard. There is a small difference in scaling: the modern standard is somewhat longer. Baroque bows are also quite different in construction and how they are handled. The modern violin bow curves downward in the middle while the baroque bow will look straight or bent outwards under tension. The baroque bow is thinner near the tip which comes to an exaggerated point.
