Repertoire refers to the collection of skills, techniques, or works that an individual or group can perform or utilize. In the context of performing arts, such as music or theater, it includes the pieces or roles that a performer is prepared to present. For example, a musician's repertoire might consist of various songs or compositions they can play. In a broader sense, repertoire can also apply to other fields, such as sports or education, where it denotes the range of abilities or knowledge a person possesses. For instance, a teacher's repertoire may include different teaching methods and strategies to engage students effectively.
