Bouzouki Asia Minor and the subsequent exchange of populations between Greece and Turkey when the ethnic Greeks fled to Greece. The early bouzoukia were mostly three-string ("trichordo"), with three courses (six strings in three pairs) and were tuned in different ways, as to the scale one wanted to play. At the end of the 1950s, four-course (tetrachordo) bouzoukia started to gain popularity. The four-course bouzouki was made popular by Manolis Chiotis, who also used a tuning akin to standard guitar tuning, which made it easier for guitarists to play bouzouki, even as it angered purists. However it allowed for greater virtuosity
Strings (tennis) are strings that have more than one filament. They are most commonly made of many filaments of nylon, but can incorporate other materials such as polyurethane, Zyex, Vectran, Kevlar, and other materials. Multi-filament strings offer better elasticity than single filament strings, but usually inferior durability. No multi-filament string holds its tension as well as natural gut, and none of them is as soft. However, in comparison to mono-filament "synthetic gut", multi-filament strings can offer a much closer approximation of natural gut's performance. The softest multi-filament strings can be made with Zyex and polyolefin, although some of the softest of these
