《無聲的樂章》系列作品，源於董陽孜有感於書寫行書、草書時的情感投入，在輕重疾徐的運筆過程中，所留下飛白、濃淡等不同的筆跡，與音樂流動的節奏、韻律性相通，在2011年時，將過去自2003到2010年間創作其它大字作品時，所收集不捨丟棄的「點畫」與「筆勢」部分字形作品中，選出100幅命名為《無聲的樂章》系列作品，並邀請不同領域的創作者，開啟一連串跨界創作計畫。2011年起，邀請建築師姚仁祿和五月天阿信、歌手陳綺貞合作，從宛如音樂符號的點墨作品中，依個人所感受到的音樂性重新排列組合，譜出充滿個人情感的無聲的樂章。2012年，邀請建築師黃宜清及音樂家李壽全合作，策辦跨領域的《無聲的樂章．變奏曲》公共藝術設置計畫，將百件作品排列組合，依照各作品特性的刻意安排，使得書法作品組合起來呈現如同繪畫作品般，有疏密、對比、輕重等主題。2014年，與建築師范赫鑠合作，透過光、影、煙塵與與聲音的巧妙安排，譜出最美麗的無聲樂章；同年，與建築師姜樂靜及楊偉林合作，將書法的韻律和張力注入空間中，為書法與建築、編織之間的跨界創作，帶來淋漓盡致的詮釋。2015年，與編織建築藝術家王文志合作的跨界創作《竹墨》展，以書法作品、鏡面、竹子的線條與書法筆劃相互交織。2016年，邀請法國Active Creative Design團隊重新演繹，嘗試應用各式創新媒材與多元形式，《無聲的樂章》作品在空間中的動力裝置裡，創造出總合共16,384種組合變化。 The Silent Music series has its origins in Tong Yang-Tze’s realization that the weight, speed and continuous movement of the dots, turns, and strokes of Chinese calligraphy’s semi-cursive and cursive scripts suggested a musical beat and rhythm. In 2011, from the hundreds of panels that made up her large calligraphic pieces dating from 2003 to 2010—each exhibiting a portion of the strokes or dots that made up an otherwise complete character—Tong choose 100 panels to be part of the Silent Music series. Upon this foundation, Tong then asked several artists to build a series of crossover creative works. The first of these crossovers was in 2011 and featured architect Yao Renlu, Ashin, lead singer of the pop band Mayday, and vocalist Cheer Chen. Referencing the ink work, which resembled musical notation, each of the three discovered a personal musical arrangement, which—following a period of deconstruction, polymerization, and reorganization—resulted in the realization of a unique and personal “silent music” composition. 2012 saw participation between architect I-ching Huang and musician Li Shou-Chuan in the creation of an public art installation project titled Silent Music．Variations. The 100 panels of the original series were organized under the theme of “density, contrast, and weight” and in accordance to what organizers saw as being their notable characteristics. The result was that the works, taken as a whole, gave every appearance of being paintings complete in themselves, as opposed to individual panels of a larger creation. Later, in 2014, in a cooperative effort with architect Frankie Fan, beautiful “silent music” was created through the skillful arrangement of lights, shadow, smoke, and sound. Finally, in 2016, the Paris-based Active Creative Design team, in a unique reinterpretation of the series, used various multimedia tools to transform Silent Music into an interactive, rotating installation that could be seen in 16,384 different ways.
