挪石社於2014年創辦葫蘆藝廊，藝廊的空間可轉換以適應不同藝術家的作品，並無處不在。葫蘆藝廊曾以可攜帶式的組裝空間，巡迴各地展出；這次特意轉化成平面空間，呈現李昀鎂的《三連音》作品。

李昀鎂一向擅長於空間佈局與排列，及沉迷於各式物件的直觀感應。在《三連音》裡，她從日常生活的靜物中汲取靈感，設計出多種別緻的形狀，並製成壓克力塑膠模板；讀者利用隨書附送的模板，在特製之三聯複印紙上勾畫輪廓，在有限的平面空間上排列出無限的組合，除複印出三重空間痕跡，也可撕下來與人分享。
 
本書與李昀鎂《行板》和《音的保持》同步出版。
 
The Calabash Gallery is an art space founded by nos:books in 2014. Its dimension transforms to accommodate different artists’ works, and it exists everywhere. The Calabash Gallery has been a portable and assembled space, touring exhibitions around. This time it turns two-dimensional, to present Lee Yun Mei’s Tuplets.

Lee Yun Mei is keen on organizing and reorganizing space, and she is blissfully content with her sensibility for everyday objects. In Tuplets, Lee takes inspiration from daily objects, designs and produces acrylic stencils of various shapes. With the plastic stencil accompanied with the book, the author / readers could trace the stencil contours on the 3-ply carbonless copy paper, organizing the objects unlimitedly in the limits of the page, leaving three layers of traces of space, to tear off and share them.
 
Tuplets is jointly published with Lee's other two titles Moderato and Tenuto.
