Coaching is a form of development in which a person called a coach supports a learner or client in achieving a specific personal or professional goal by providing training and guidance. The learner is sometimes called a coachee. Occasionally, coaching may mean an informal relationship between two people, of whom one has more experience and expertise than the other and offers advice and guidance as the latter learns; but coaching differs from mentoring in focusing on specific tasks or objectives, as opposed to more general goals or overall development.
Opera (Italian: [ˈɔːpera]; English plural: operas; Italian plural: opere [ˈɔːpere]) is a form of theatre in which music has a leading role and the parts are taken by singers. Such a 'work' (the literal translation of 'opera') is typically a collaboration between a composer and a librettist and incorporates a number of the performing arts, such as acting, scenery, costumes and sometimes dance or ballet. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor.
