How can you 描述 the 质地（纹理、织体） of sounds?


描述 The 质地（纹理、织体） of Sounds

One 方面 of 声波 that 传统 樂/乐 记谱法 is very poorly equipped to deal with is the 质地（纹理、织体） or 音色 of the 声波 There is no accurate way to 描述 樂/乐 音色 using 传统 记谱法

When we 描述 a 声波 as noisy 声波 文件 or pitched 声波 文件 we are referring to its 音色 All 声 have a 独特 音色 and it is this property of 声波 that allows us to tell 声 apart

聆 Challenge
How many different 音色 can you 听 in this recording? Try to identify as many as 可能

Can you find more than you friends?


声音 Fingerprint

A sound’s 音色 could be thought of as its fingerprint Each 声波 will have a 独特 音色 Even 声 coming from the same 源 can possess different 音色 soft hit hard hit The 特殊 音色 that a 声波 has is 创作 by a 组合 of all its 属性


Activity
Discuss with a partner how you might best 描述 the 品质 of the 跟随 声 Think about their 形状 质地（纹理、织体） 相对 noisiness? As well as their 音高 响度 and 时值

You might find it useful to 草图 out pictures of how the 声 might look? see also 绘制 声

Distinguishing Many Sources
音色 allows us to 区分 between different 声波 源 and to separate out individual 声 It is 音色 that allows us to identify the many different 声 within a 作品

聆 Challenge
听 to these two 声波 clips of 传统 乐器

An 乐器 playing the 音符 D2
听 to the 品质 of this 声波 and compare it with the 声波 below

A second 乐器 playing the 音符 D2
Both 乐器 are playing the same 音符 but they 声波 very different

Did they 声波 different? In what way?

This 例如 demonstrates to us that there is much more to 声波 than 音高

类似 Timbre
If we are presented with many 声 that have 类似 音色 then it can be difficult to identify the 数 of 源

Think for 例如 of being in a crowded place a shopping 中心 or a football stadium where there are many 人 talking at once We no longer 听 the individual voices but a mass 声波 for the whole crowd

Voices
In this 例如 the many voices blend together into a cacophony of 声波 Gradually as the layers of voices 薄 out we begin to 听 more and more 细节 from individual phrases

In 传统 樂/乐 orchestration takes advantage of 音色 allowing 樂/乐 元素 to be separated and 清楚 distinguished

制作 樂/乐 with 声 allows us to 探索 this idea even further and positions 音色 as the most 重要 方面 of 樂/乐

Each of these 对象 has a 独特 音色 That is how we can tell them apart
