An "étude" is a musical composition designed to provide practice material for musicians, particularly instrumentalists. These pieces often focus on specific technical skills, such as finger dexterity or breath control, and are commonly used in the study of instruments like the piano or violin. In addition to their educational purpose, études can also be performed in concert settings, showcasing the musician's technical prowess and artistic interpretation. Famous composers like Frédéric Chopin and Franz Liszt have written notable études that are celebrated for their beauty and complexity, making them popular among both students and professional musicians.
