Does Classical Music consist of electronic music?

No. Generally, Classical music consists of music created by an Orchestra or a smaller group of musicians who all play 'live' together on real instruments. These might include violins, violas, cellos, clarinets, oboes, trumpets, horns cymbals and kettle-drums, for example. There may also be vocal performers. The group all be playing from a score written by the composer of the music. The group's performance is often co-ordinated by a person known as a conductor who gives visual cues to ensure the intended time, feel and dynamics of the piece are adhered to. Hope that answer helps.
