「天狼星口琴樂團」為台北市立案演藝團體，於2001年時成立，其前身是由三位台中一中口琴社校友：彥銘、碩懋和阿剛所組成的校友隊。由於中一中口琴社的代表動物是狼，因此在團名之中加上「狼」字以表示其緣起。然而歷經十數年的沿革，現今的天狼星樂團已脫離校友隊的性質，成為台灣新一代口琴重奏代表性樂團之一。

從2001年成立到2003年兩年內樂團便拿下了包括台灣口琴節、台北重奏大賽等等八座台灣全國比賽的冠亞軍獎牌。2004年獲亞太口琴節（於香港）三重奏公開組亞軍。2006年受邀於亞太口琴節（於台灣）開幕晚會擔任表演嘉賓。2008年錄製第一張專輯「Why So Serious?」2010年獲得亞太口琴節（於新加坡）最佳和弦口琴演奏、最佳低音口琴演奏、三重奏公開組亞軍、以及小合奏公開組季軍，並於中視超級星光大道星光傳奇賽節目中與歌手魏如昀合作演奏組曲: The Moment/當我們同在一起。2011年錄製第二張專輯「天狼星的影視配樂選輯」，且應新加坡口琴愛好者協會之邀請於濱海藝術中心（Esplanade）舉行連續兩晚的演奏會。會後並前往馬來西亞進行交流訪問。2012年受邀於亞太口琴節（於馬來西亞）達人音樂會擔任演出嘉賓。在今年（2013年）10月份，天狼星口琴樂團更受邀於具有「口琴界的奧林匹克大賽」美稱的世界口琴節（於德國）中擔任演出嘉賓並舉行講座。現役團員為：陳彥銘、黃啟書、林其毅、陳奕翔、蔡明憲、張晁滕等六位。

由2004年至今，天狼星樂團定期在台北知名的Live House「女巫店」演出，也是第一個將口琴音樂帶向台灣地下音樂界的團體。團長陳彥銘有感口琴音樂在台灣的弱勢，希望能藉由在女巫店的演出讓更多非口琴人接觸到口琴重奏這項特殊的音樂形式。在這幾年的演出經驗中，藉由和許多其他的音樂人交流，天狼星樂團也確立了自身的演出風格與走向。

口琴是一種具有迷人聲響的樂器，而口琴重奏這種組合的形式，更是口琴音樂藝術的一種極佳的呈現方式。團員們使用不同大小、不同功能的口琴。分司旋律、節奏、合聲、低音等音樂的各部份，一起營造出張力十足的口琴重奏音樂，構造簡單但卻魅力十足。誠摯的希望和大家分享口琴重奏的奧妙與樂趣！
