3. Violin
Although many fretless string instruments are very hard to master, we have chosen violin as a representative. The violin as we know it today evolved in Renaissance Italy, and remained one of the most played instruments throughout the world. The first thing that makes it one of the hardest instruments to play is the unnatural position that it is held up, resting on the shoulder and making tension in left arm, shoulders and neck. Secondly, it is separating left and right hands, while they do different things. Third and the most important is the very technique of playing the violin, which reflects in the way musician produces tone colors, vibratos, dynamics, etc. which is unique for every player and perhaps that is the most challenging part of playing this instrument.
