“白日梦蓝”是一本造建筑工作室联合独立音乐人铁阳，在公益组织“种太阳”的夏令营项目中，带领湖北浠水县大别山区的留守儿童们与来自全国各地的大学生志愿者们，共同设计并亲手搭建的一座“会唱歌的房子”，为孩子们带来属于他们的乐队的夏天。

‘Blue Daydream’ is a ‘singing space’ that designed by one take architecture and independent musician Tieyang. In the Summer Camp that organized by non-profit organization Sunners in Xishui County, Hubei Province, One Take Architects, Tieyang and Sunners, together with college volunteers and left-behind children, designed and built this spatial musical installation together, which brought the children their own “The Big Band”.

“白日梦蓝”由十组构筑物构成，分为三个声部，每个声部 3-5 个音阶。主要发声部位为三种不同直径的 PVC 排水管，并由顶部的蓝色给水管进行音高的调节。PVC 给排水管在乡村极其常见，乡村里的民宅大多外露排水系统以节省造价方便检修，因此很多孩子对它们并不陌生。它们拥有极为丰富的转接配件系统，这帮助孩子们很容易地理解了原理并快速装配完成，甚至摸索更多的组合方式。

‘Blue Daydream’ consists of 10 groups of structures divided into 3 scales of parts, and each part includes 3-5 scales. Its main sounding part is the PVC tube with three different diameters, for which the pitch of sound could be adjusted by the blue water supply pipe on the top. This kind of tube is one of the most common and accessible material/tools in the rural areas of China. To save the cost of facilitating installation and maintenance, most of the drainage systems are exposed out of the house in rural areas. Therefore, children here are pretty familiar with it in their daily life. There is a multiple and flexible system of adapters, which allows children to easily understand the assemble principle of the tubes. Thus, they could quickly assemble them, even exploring more different ways of combinations.

使用 PVC 给排水管设计发声器的灵感来自于巴布亚新几内亚原住民的竹制打击乐器——他们使用不同直径的竹子，打通内径并捆扎到一起，击打发出生声音形成极为丰富有力量的旋律与节奏。为了简化搭建流程，我们以 110mm 直径的排水管为基础，将白日梦蓝的底座设计为统一尺寸的基础——即“凳子”，成为白日梦蓝的基本构架。与此同时，110mm 直径的排水管也是孩子们的“画卷”——根据听到的音乐，孩子们尝试在管壁上进行创作，再把它们组装进入白日梦蓝。

The inspiration for using PVC tube as a sounder came from the bamboo percussion instruments created by the locals of Papua New Guinea. They bundle bamboos of different diameters together and hollow them out, so rich and powerful melody and rhythm could be formed by hitting them.

In order to simplify the construction process, the basement of the Blue Daydream is designed to be uniform sized stools that consisted of 100-millimetre-diameter PVC pipes. At the same time, the 110mm diameter PVC pipe is also a “picture scroll” for the children—they created their own painting on the pipes according to their feelings about the music they heard, and assemble them into Daydream Blue after they finished their painting.
