Purple Songs Can Fly is a music therapy program to aid in the emotional and physical healing process of children being treated for cancer and blood disorders at Texas Children's Hospital. An in-house music studio allows project staff to work with inpatient children to compose and record their own songs which are burned on purple CDs. The program's partnership with NASA and Continental Airlines adds another dimension for the children. The compact discs are brought aboard space shuttle missions and commercial flights and flown to places on earth and into space. The CDs are returned to the children, autographed by astronauts and pilots with all flight information included.

The program aims to provide an outlet for inpatient pediatric cancer patients to express their emotions through composing and performing music.

Over 138 songs have been written and recorded to date. A second site based in Tokyo, Japan is currently under development.
