Tuned the same as the violin, the present mezzo with a body length of 38.2 cm was added to the new violin family when musicians found that even an excellent concert violin did not have the power to match the other members of the group.

According to scaling theory, this instrument is made 1.07 times as long as the violin, has more power than the normal violin and seems most satisfactory. It has the normal violin resonance placement, yet it is adjusted to have conventional violin mensure for the player. In fact, several musicians have indicated that it may be the violin of the future.
