What does Buddhism say about creativity and spiritual development? Does Buddhism say anything about a relationship between greatness in art, music or other creative areas, and spiritual development? For example, consider the well-known great composers: is there anything to say about how they are able to produce astoundingly complex and beautiful works, like symphonies? (Answers from any tradition are fine.)

Addition: I mean being actively creative, not just listening to music. Is being active and creative valued in Buddhism, or is the point to extinguish everything? What is the purpose of life besides trying to scream and run away? (OK, getting a bit frustrated here.) If life arose for any reason, would it not be to enjoy being in all its forms, and all activities? Or is that a Vexing Question?
In Asia, the various forms of Buddhism have inspired uncountable number of art objects created over the centuries: statues, monuments, temples, icons etc. Some art forms, particularly Japanese ones, are considered no less than expressions of the Enlightened Mind.

Many Zen Masters were known for their calligraphy, drawing, and/or poetic skills. The now famous music of shakuhachi flute was popularized by the Fuke sect of Buddhistm.

Late Chogyuam Trungpa Rinpoche was known for his endless creativity. Check out his True Perception: The Path of Dharma Art, Timely Rain: Selected Poetry of Chogyam Trungpa, The Art of Calligraphy, and other writings.

Teacher I.L. declared awakening of the enlightened creativity, as a tool for the universal benefit to oneself and others, to be the point of Enlightenment. From other teachers I heard that creativity is one of the hallmarks of Enlightenment, as the mind without defilements uncovers potential for unlimited uninhibited creation.

So in short, most of the time Buddhism welcomes art and creativity, especially the kind that either expresses Enlightened Mind or popularizes Dharma.
