Ligeti is one of the most original and influential composers between the 20th and 21st centuries. His works, that reflect various sound experiments, amazed his audiences and brought him many international composition awards. One of these works is his first book of etudes for piano. The main body of this paper is the examination of the first book of etudes. It contains chapters of discussion on related articles, Ligeti ´s biographical sketch, Ligeti´s composition and characteristics, and the analysis of the first book of etudes for piano. The analysis focuses on thematic patterns, rhythmic structures, design of musical climax, and performance suggestions of each etude. It was found that these etudes combine complex polyrhythm, harmonic pattern from Jazz music, and even the characteristics of Bartók, Debussy, and Liszt. Its original sound effect and new way of performance make each of these etudes unique and worthwhile to study within the modern piano repertoire.
