Those studying composing/arranging and listening in SQA Music exams pretty soon come upon variation form. If you’re lucky enough to have an iPhone or iPad you can download a free app containing a recording by Kimiko Ishizaka along with a score (with moving cursor) of one of the best sets of variations of all time, Bach’s Goldberg Variations.

Honest debate impels me to include points of view which do not match my own. In this regard here is an article in which it it stated that parents who invest in music lessons for their children, in the hope of improved academic ability, are wasting their money.
