from bronze Buddhist statues and shrines, to highly colorful thangka paintings and mandalas. Thangkas are Tibet's traditional cloth paintings. Rendered on cotton cloth with a thin rod at the top, they portray Buddhist deities or themes in color and detail. Architecture Tibetan architecture contains Chinese and Indian influences, and reflects a deeply Buddhist approach. The Buddhist wheel, along with two dragons, can be seen on nearly every Gompa in Tibet. The design of the Tibetan Chörtens can vary, from roundish walls in Kham to squarish, four-sided walls in Ladakh. The most distinctive feature of Tibetan architecture is that many of the houses and monasteries are built on elevated, sunny sites facing the south, and are often made out of a mixture of rocks, wood, cement and earth. Little fuel is available for heat or lighting, so flat roofs are built to conserve heat, and multiple windows are constructed to let in sunlight. Walls are usually sloped inwards at 10 degrees as a precaution against the frequent earthquakes in this mountainous area. Standing at in height and in width, the Potala Palace is the most important example of Tibetan architecture. Formerly the residence of the Dalai Lama, it contains over one thousand rooms within thirteen stories, and houses portraits of the past Dalai Lamas and statues of the Buddha. It is divided between the outer White Palace, which serves as the administrative quarters, and the inner Red Quarters, which houses the assembly hall of the Lamas, chapels, 10,000 shrines, and a vast library of Buddhist scriptures. The Potala Palace is a World Heritage Site, as is Norbulingka, the former summer residence of the Dalai Lama. Music The music of Tibet reflects the cultural heritage of the trans-Himalayan region, centered in Tibet but also known wherever ethnic Tibetan groups are found in India, Bhutan, Nepal and further abroad. First and foremost Tibetan music is religious music, reflecting the profound influence of Tibetan Buddhism on the culture. Tibetan music often involves chanting in Tibetan or Sanskrit, as an integral part of the religion. These chants are complex, often recitations of sacred texts or in celebration of various festivals. Yang chanting, performed without metrical timing, is accompanied by resonant drums and low, sustained syllables. Other styles include those unique to the various schools of Tibetan Buddhism, such as the classical music of the popular Gelugpa school, and the romantic music of the Nyingmapa, Sakyapa
