French Study, or Etude in French, is a term used to describe a piece of music composed for the purpose of developing a particular skill or technique. It is often used by classical musicians to practice and improve their playing. Etudes are usually short pieces that focus on a specific technical challenge, such as playing fast notes or playing with a certain articulation. They are also used to help students learn how to play different musical styles. Etudes can be found in many different genres, from classical to jazz and even pop music.
