In Romanian, the word lăutari refers to highly skilled professional Romani (Gypsy) musicians. By interacting with Romanian culture and tradition, the lăutari settled down in the country and developed a unique musical tradition. Their music is characterized by intricate, elaborate, and refined ornamentation; its execution requires a highly level of technique. George Enescu, regarded as Romania's most influential musician, was affected by lăutari music. He created a unique musical language that recreates Romanian character by using lăutari elements. This dissertation examines how to approach Enescu's Violin Sonata No. 3 and perform it by understanding the characteristics of lăutari music as well as the work's use of such lăutari violin techniques as diverse expressive slides, vibrato, double stops, various ornaments, artificial harmonics, imitation of folk instruments, and a variety of bow strokes. Enescu's Violin Sonata No. 3 is regarded as a challenging work in the violin literature requiring a high level of violin technique. Although the standard violin repertoire is enormous, many violinists are looking to rediscover new and challenging repertoire, distinguish themselves from others, and promote themselves as professional performers. Therefore, this study should help violinists to approach the idiomatic violin writing of Enescu's sonata, especially its lăutari techniques and style.
