A descriptive review of literature on synesthesia which emphasizes color hearing (chromesthesia) in musical experiences

A re-study of synesthesia, a much-discussed subject in the early days of psychology, is up-dated and compared to perceptual experiences in the drug-addicted culture of today's youth. A brief comparison of the two is made in this thesis, which brings a new idea to early studies made within a vast amount of literature written over a century ago. Colored hearing, or chromesthesia, is emphasized herein, in regard to music, or tonal perception. Examples are given of famous composers who were·also famous synesthetes.
