Art students should play piano pieces that enhance their creativity and technical skills. Pieces like Chopin's "Nocturnes" and Debussy's "Clair de Lune" are excellent choices as they offer a blend of expressive melodies and intricate harmonies. These pieces not only develop technical proficiency but also foster emotional expression, which is crucial for artists.

The selection of piano pieces for art students is significant because it can directly impact their artistic development. According to a study published in the Journal of Aesthetic Education, engaging with music can enhance cognitive functions such as creativity and emotional intelligence. Chopin's "Nocturnes," for instance, are known for their expressive melodies and rich harmonies, which can help students develop a deeper understanding of musical expression. Debussy's "Clair de Lune," on the other hand, is a masterpiece of impressionistic music, which can inspire students to explore their own artistic visions. These pieces not only challenge students technically but also encourage them to think outside the box, fostering a sense of innovation and originality essential for artistic growth.
