Of all the other people in the Caucasus the traditional music of Azeris* seem to most easily be categorized into 3 definitive streams:
- classical mugham stemming from an Iranian urban influence;
- ashiqs, which shows direct connection to Turkic bardic tradition; and
- rural folk or peasant music.
Typically, mugham is known for its musical development and ashiqs for their lyrical/textual development. The folk music, in comparison, is very simple. Technically speaking, the thing that ties them all together is a monodic music system based on tetrachords. This translates into the ability of each stream to make meaningful musical phrases out of the primarily stepwise motion of only a few notes.
