what is celtic mean?
The definition of Celtic music must start with a definition of what a Celt is. The origin of the term goes back to the word keltoi, which was used by the ancient Greeks to refer to certain barbarian tribes. In modern terminology, Celtic is used to refer to a certain branch of the Indo-European language group. Some of the tribes called keltoi spoke Celtic languages. However, it is not certain that the Greeks applied keltoi only to Celtic-speaking tribes.
