Music
Music is an art form and cultural activity whose medium is sound organized in time. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek μουσική (mousike; "art of the Muses"). See glossary of musical terminology.
Music Therapy
Music therapy is the clinical and evidence-based use of music interventions to accomplish individualized goals within a therapeutic relationship by a credentialed professional who has completed an approved music therapy program. Music therapy is one of the expressive therapies, consisting of a process in which a music therapist uses music and all of its facets—physical, emotional, mental, social, aesthetic, and spiritual—to help clients improve their physical and mental health. Music therapists primarily help clients improve their health in several domains, such as cognitive functioning, motor skills, emotional development, communication, sensory, social skills, and quality of life by using both active and receptive music experiences such as improvisation, re-creation, composition, and listening and discussion of music to achieve treatment goals. There is a wide qualitative and quantitative research literature base which incorporates psychotherapy, biomusicology, musical acoustics, music theory, psychoacoustics, embodied music cognition, aesthetics of music, sensory integration, and comparative musicology.
Therapy
Therapy (often abbreviated tx, Tx, or Tx) is the attempted remediation of a health problem, usually following a diagnosis. In the medical field, it is usually synonymous with treatment (also abbreviated tx or Tx). Among psychologists and other mental health professionals, including psychiatrists, psychiatric nurse practitioners, counselors, and clinical social workers, the term may refer specifically to psychotherapy (sometimes dubbed 'talking therapy'). The English word therapy comes via Latin therapīa from Greek: θεραπεία and literally means "curing" or "healing".
Therapy
I used to be under the impression that in some kind of wanky, bullshit way, acting was like therapy: you get in and grapple with and exorcise all those demons inside of you. I don't believe that anymore. It's like a snow shaker. You shake the thing up, but it can't escape the glass. It can't get out. And it will settle until the next time you shake it up.
