A modern drum and bugle corps, is a musical marching unit consisting of brass instruments, percussion instruments, synthesizers, and color guard. Typically operating as independent non-profit organizations, drum corps/bands perform in competitions, parades, festivals, and other civic functions. Participants of all ages are represented within the band activity, but the majority are between the ages of 13 and 22.〔(【引用サイトリンク】title=DCI.org: Introduction )〕 Competitive corps participate in summer touring circuits, such as Drum Corps International (DCI) and Drum Corps Associates (DCA). Corps prepare a new show each year, approximately 8–12 minutes in length, and refine it throughout the summer tour. Shows are performed on football fields and are judged in various musical and visual categories, or "captions". Musical repertoires vary widely among corps and include symphonic, jazz, big band, contemporary, rock, wind band, vocal, Broadway, and Latin music, among other genres. Competitive junior corps usually spend between 10 and 15 weeks on tour over the summer, practicing and performing full-time.〔(【引用サイトリンク】url=http://www.regiment.org/calendar/index.cfm )〕 All-Age and Alumni corps have less demanding schedules, practicing and performing mostly on weekends. == History == Drum and bugle corps stems from a rich American and Canadian military history, separate from other marching musical activities. Beginning after World War I through the 1970s, corps and competitions were often sponsored by the VFW, Scout troops, churches, the Royal Canadian Legion, and the American Legion. Owing to many of these groups' roots, corps were traditionally militaristic. By the late 1960s, many corps wanted more creative freedom and better financial compensation than was offered by their sponsoring orgnanizations. Some felt the prize-money structures, based on competitive placement, were not fairly compensating all corps for their appearances. Additionally, some felt the current judging rules were stifling musical and theatrical possibilities. At the peak of North American drum corps participation (with perhaps a thousand active corps in the U.S. and nearly as many in Canada), several corps decided to "unionize", as stated by Don Warren (founder of the Cavaliers). They formed their own organizations, which ultimately led to the formation of DCA in 1965 and DCI in 1972. By this time, many corps had already lost their church or community sponsors. For the corps that remained, longer travel times were necessary to attend the shrinking numbers of contests, further adding to the financial and time demands on the organizations and their individual members. At the same time costs for the increasingly complex field shows mounted and creative and instructional demands rose leading many competitive corps to falter and become inactive. By the late 1990s only a fraction of the corps that existed in the 60s and 70s remained, although several new corps, some of which have become very successful, did start up along the way. Non-competitive classic-style corps (often and sometimes inaccurately known as "alumni corps") saw a renaissance beginning in the mid-1980s and they continue to organize in the 21st Century; members often remain vigilant about the traditions and virtues of the drum corps activity before the advent of electronic technology, band instruments, dancing and rapping. Freed from the traditional and more-restrictive judging rules of the late 1960s, bands began making innovative changes such as the use of multi-valve horns, wide-ranging tempos, intricate asymmetric drill formations, elaborate guard costumes and props, and the use of stationary orchestral percussion instruments. A common criticism of drum corps is that it has become too similar to marching band, although in truth the two activities have merged over the years. A few corps still utilize the traditional G Bugle which is very rarely found in marching band. The competitive season for corps is in the summer rather than fall, with auditions and initial ensemble rehearsals beginning as early as late October of the previous year. The top-tier competitive bands are often very complex and more professional than the average marching band, as members in full-time touring bands have no distractions outside of band during the season and membership is achieved only through highly competitive auditions. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Drum and bugle corps (modern)」の詳細全文を読む スポンサード リンク
