What is The Meaning of "Avant-Garde"?

In fine art, the term "avant-garde" (from the French for 'vanguard') is traditionally used to describe any artist, group or style, which is considered to be significantly ahead of the majority in its technique, subject matter, or application. This is a very vague definition, not least because there is no clear consensus as to WHO decides whether an artist is ahead of his time, or WHAT is meant by being ahead. To put it another way, being avant-garde involves exploring new artistic methods, or experimenting with new techniques, in order to produce better art. The emphasis here is on design, rather than accident, since it seems doubtful that a painter or sculptor can be accidentally avant-garde. But what constitutes 'better' art? Does it mean, for instance, painting that is more aesthetically pleasing? Or more meaningful? Or more vividly coloured? The questions go on and on!
