>Sam (together) + Geet (Song); earlier included vocal, instrumental and dance but now used only to refer to music.
from ITC Sangeet Research Academy glossary
Sangeet is a word which doesn’t really translate into English. In its most general sense it is considered synonymous with the term “music”; however it is actually a threefold artform of vocal music, instrumental music, and dance. Since classical dance is also a component, it is not strictly synonymous to the Western term “music”.
There is a historical reason why sangeet is composed of these three artforms. In the Vedic and post Vedic period it was customary to perform mythological dramas. These dramas used dancers to mime the story, instrumentalists to play the musical accompaniment, and vocalists to tell and sing the story.
There is a standard terminology whenever one wishes to be specific. Dance is refered to as “nritya”, vocal is refered to as “gayaki”, and instrumental is known as “vadhya sangeet”.
