Final answer:
The question about Emma's flute practice schedule is not directly answered by the provided excerpts, which instead offer a thematic connection to music and the arts. Regular practice is typical for musicians, implying Emma likely has a structured routine.
Step-by-step explanation:
The question, 'When does Emma practice the flute?' seems to relate to an individual's specific schedule for practicing a musical instrument, which might not be explicitly stated in the text provided. However, the various excerpts include references to music and the arts, such as a student playing music, a reference to the Shanghai School of Art, and descriptions of musicians and dancers. These excerpts illustrate a thematic connection to the performing arts but do not provide a direct answer to the question of Emma's practice schedule.
It's worth noting that practicing a musical instrument like the flute would require dedication and typically includes regular sessions, often daily, to improve skill and technique. Therefore, without specific information on Emma's routine, one can infer that she likely practices regularly within a schedule that fits her other commitments and artistic goals.
