声景观（声景） 樂/乐 is made of 录制 声 from the world around us Composers combine and 操控 different 录音 of the world to 创作 new 'sonic environments'


What is 声景观（声景） Music?

作品 of 声景观（声景） 樂/乐 or 'soundscapes' for short are 通常 edited in some way Soundscapes will most often try to 突出 the key 声 within 录音 and take the 听众 on a 旅程 in 声波


Fact
A 领域（野外） 錄/录 is made from 类似 材料 to a 声景观（声景） 作品 but is often left unedited and 'raw'


Key Manipulations in 声景观（声景） Composition

编辑 and 处理 过程 in 声景观（声景） 樂/乐 are often subtle so as to keep the 听众 believing in the new 声音 环境

Two of the most 经常 used 技术 are
•Filtering

and
•Splicing



What is Filtering?

Filtering allows the 作曲家 to isolate or 突出 特定 片段 of the 声波 频谱 within the 声景观（声景）

You can actually see the filtering of the 声波 take place in the 声谱 图像 below

The orange colour indicates 声波 you can see the 滤器 coming into 效果（效应） from left to right as the orange colour disappears Leaving only a 窄 范围（排列） of 声波

You can also 听 the 滤器 being used It focuses in on a 特定 part of the 声景观（声景） 錄/录 highlighting only the 特定 foreground bird calls

作曲 of Note
One 例如 of a 声景观（声景） 作品 that makes fantastic 用 of filtering is Kits Beach 聲行/声漫步 by Hildegard Westerkamp

What is Splicing?

切片 is a 过程 of cutting the 声波 in which the 作曲家 selects the most significant parts of the 錄/录 and brings them together

The 原始/原创 un-spliced 錄/录
Squelching down a muddy path

The spliced 声波 Squelch Squelch
The 拼贴 工具 has been used to select and condense the most interesting parts of the 声景观（声景） 錄/录 We no longer 听 the footsteps only the squelchy 声波 of the sticky mud

作曲 of Note
A good 例如 of 声景观（声景） 作曲 which uses the 过程 of 切片 is Luc Ferrari’s 作品 Presque rien [Almost Nothing] No 1

创作 声景观（声景） Works
声景观（声景） 作曲 通常 探索 the interesting and 独特 声 available in a 特殊 位置

These 地点 don’t have to be outside as the two examples provided have been but might also be 内在 声 think for 例如 of the 声 in the canteen and school hall at lunchtime

听 to this!
The 声波 card pack “Kitchen Sounds” provides lots of 录音 of the Kitchen 声景观（声景）

The scale of the 景观 might be really large such as the 声波 of 活动 in a whole city or really small such as the 声 活动 in a single shrubbery


Key 窍门 for 创作 a 声景观（声景） Piece

声景观（声景） 作曲 relies upon detailed 聆 and clever 编辑

Often there is a play between 声 that are in the foreground and those that are in the 背景

声 might move from being in the foreground to being in the 背景 or vice versa

Subtle 编辑 can 变形 a “normal” “everyday” 声景观（声景） into something mysterious and wonderful 声波 designers in 电影 often do this to add to the story of the 电影 and the world of the 电影 in which it takes place

声景观（声景） therefore is 不 about simply presenting 预录 soundscapes but in telling a story through 控制 and 处理 of these 预录 soundscapes

作曲 Tip
Having a 持续 流 of 声波 to act as a backdrop will hide some of your edits by providing an unbroken 背景 against which other 声 can emerge and disappear
