Often, when a student sees something he or she really wants, then a phrase can be more easily encouraged.

The rhythms of sound have a powerful impact on cognition. The information most adults consistently recall from childhood is songs and rhymes.

People have at least seven distinct intelligences. One of these intelligence areas is the musical area. Often people with special needs learn best through music because that part of the brain is an older part of the brain and less likely to be damaged from birth defects, accidents, etc. Enriched environments literally change the brain. Intelligence is not static.
