Tango is usually played either por media (on the fifth string in A phyrgian, relative to the capo) or por arriba (on the fifth string in E phyrgian, relative to the capo). Its compas is a simple four-count, with accents on the 2, 3, and 4. This basic count is often grouped in sets of two or four, making for musical phrases in 8 or 16 counts. Though the accents on the 2, 3, and 4 can be combined in different ways, the one count is always de-emphasized.
