The Tagh is a genre of Armenian monodic song writing. Its origin is ancient and its content and advanced melodic line remind one of future vocal and instrumental arias.

The characteristics of the tagh are its expansiveness of form and volume, its free melodic style, the existence of instrumental passages and richness of rhythm. The tagh is basically a lyric song but it is not canonic like the sharakan. There are two types of taghs - religious and secular. St Narekatsi's taghs are the unsurpeassed monuments of the music.
