Cove allows users to build instrumental music to match their mood (ranging from gentle, clouded, playful, longing, calm, to struggling). The app is intended to help users express their emotions in stressful scenarios where verbal expression might not be effective. The app is founded on the idea of expressive therapy. The initial mood rhythm is supplemented by bases and melodic patterns with a filter as a finishing touch. This degree of variation allows for layered generation of “mood music” with the opportunity to assign emotional buttons and written details before being archived in a music journal. Cove can be used to track and express emotions and was developed primarily for adolescents, but is appropriate for use by all age groups.
