Azerbaijan lies to the east of Turkey, and is separated from Turkey only by the narrow country that is Armenia. To the east of Azerbaijan lies the Caspian Sea, and then Turkmenistan of Central Asia. Azerbaijan is bordered on the north by Georgia and Russia, and on the south by Iran. The people of Azerbaijan are primarily a Turkic people, but much of their culture, including their music and dance, is more Persian in nature. Azeri dance music, like Persian dance music, is in a 6/8 time signature, and many of the Azeri dances use a distinctive triple-step, similar to, but slightly different from, the triple-step used in Persian dance.
