Live PA (sometimes written LivePA, meaning Live Personal Appearance or Live Performance Artist) is the act of performing electronic music in a concert setting. While the term "Live PA" literally means "Live Personal Appearance", a legal term originally used to protect promoters when performances are occasionally prerecorded, in common usage it refers to live performance of electronic music, via synthesizers, samplers, and sequencers.〔(【引用サイトリンク】url=http://www.livepa.org/faq/#what_is_a_Live_P.A. )〕 In a performative context, the term was originally used to refer to live appearances, initially at rave events in the late 1980s,〔(【引用サイトリンク】url=http://www.atarimusic.net/component/muscol/D/54-dnwll )〕 of studio based electronic dance music artists. The concept of the Live PA helped provide a public face for a scene that was criticized as ''faceless'' by the mainstream music press.〔(【引用サイトリンク】url=http://www.atarimusic.net/component/muscol/D/54-dnwll )〕 The trend was quickly exploited by a music industry desperate to market dance music to a popular audience. == Execution == Generally Live PA artists use a central sequencer which triggers and controls sound generating devices like synthesizers, drum machines, samplers. The resulting audio outputs of these devices are then mixed and modified with effects using a mixing console. Interconnected drum machines and synthesizers allow the electronic Live PA artist to effectively orchestrate a single-person concert. Hand-played keyboards, hand-triggered audio samples, live vocals, and other live instruments can augment the performance as well. Some artists like Brian Transeau and Jamie Lidell utilize hardware and software tools custom-designed for live expression and improvisation. By arranging, muting, and cueing pre-composed basic musical data (notes, loops, patterns, and sequences), the Live PA artist has the freedom to manipulate major elements of the performance and alter a song's progression in real-time. Many Live PA artists try to combine the qualities of both traditional bands and dancefloor DJs, taking the live music element from bands, and the buildup and progression from song to song of DJs, as well as the sheer volume of music controlled by a single person (of a DJ as opposed to a band). By allowing the sequencer to handle the playing of basic musical data (as defined above), the Live PA artist can focus on controlling what is most important to the listener: the actual musical quality of what is emanating from the speakers. 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「Live PA」の詳細全文を読む スポンサード リンク
