Final answer:
The statement regarding music therapy in the South African project is true, as music therapy is a recognized practice to aid well-being and healing, and its effectiveness is evidenced in various instances and studies.
Step-by-step explanation:
The statement that 'The musicians in collaborative work: negotiations between music therapists and community musicians in the development of a south African community music therapy project Ost Hizan h et al were providing music therapy' is True. Music therapy has been recognized as an effective tool in promoting well-being and healing in communities, acting as a sort of universal language that can express emotions. This is supported by cases such as the study by Thomas Fritz et al., which demonstrated the recognition of emotions in music by individuals with no previous exposure to Western music, and Robert Gupta's use of music therapy to assist marginalized individuals in society. These instances illustrate the power and role of music in therapy and community development, making it a pertinent approach in such projects.
