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.
Church
It is imperative that the contrasts between Christianity and Jesus be clearly revealed and strongly emphasized. First, because the real significance of Jesus is obscured by the widespread belief that organized Christianity truly reflects his religion; and second, because it will be practically impossible to abolish giant evils while they are hallowed by the blessing of the churches. As long as ministers and laymen labour under the delusion that contemporary Christianity is the same religion that Jesus practised they will remain immunized against his way of life and will lack the vision and power to overthrow entrenched iniquity.
