As mentioned in Webster's Dictionary intelligence includes the ability to understand, to apply knowledge, to use reason skillfully, and to manipulate one's environment. The view that intelligence comprises many different abilities is supported by current trends in neurology and cognitive psychology. Among researchers who have identified various types of intelligence, Howard Gardner's (1993) pioneering work at Harvard on multiple intelligences has helped people understand that intelligence is multifaceted. He defines intelligence as "a computational capacity-a capacity to process a certain kind of information-that originates in human biology and human psychology. The core operations which comprise musical intelligence include the capacities for musical composition, performance, and appreciation, accompanied by skills in the recognition of musical pitch, tone, and rhythm. Most of these elements require that an individual is capable of hearing, yet this is not always the case. In fact, deaf individuals are typically capable of recognizing rhythmic aspects of music in movement and motion.
