In the main, workshops and courses are held to allow for education in a particular subject matter. They can be exploratory in scope or operate within highly defined areas, but they all have in common the idea of personal progress in some way. For example, workshops and course in music could be aimed at beginners to allow them to try their hands at several different instruments. More advanced courses might be for tuition into just one instrument to enable intermediate players to gain advanced skills. Both workshops and courses are conducted throughout the academic year, and they are run formally and informally. Some require attendees to pay in advance for their tuition, whereas some work on a voluntary payment basis. Others, still, are completely free. Workshops and courses cover every area of life, from religion to car mechanics.
