 So, we invite you to explore the healing power of music and sound. Whether you are in the healing professions and would like to make your work even more graceful and effective, or you just want music to dance to, to relax with or to take you to deeper states of consciousness on your own healing, there is much to choose from, lots to enjoy—one world, so much music. 

因此，我們邀請您探索音樂和聲音的治愈能力。無論您是在康復專業中，還是想讓您的工作更加優雅和有效，還是只是想听音樂跳舞，放鬆一下或讓您進入更深層次的意識，就可以自己恢復，就可以了。從很多選擇中享受一個世界，那麼多的音樂。
