Drones in Music
Drones are 已有 in different 乐 from across the world They are 延（续） or 反复 音 which 環/环 out for extended 周期（时期） of 时间

They can evolve slowly and 创作 rich and 复杂 质地（纹理、织体）

Drones are 已有 in Aboriginal 樂/乐 Indian 樂/乐 Japanese Gagaku and even Western 乐

Famous examples of drone 乐器 are the bagpipes and the didgeridoo Hurdy Gurdy

Fact
In Canada they are celebrating Drone 樂/乐 with a whole day dedicated to it! Drone Day

There website also 包含 a large 选择 of links to examples of drone 樂/乐

功能（函数） in Music
Drones often serve as a strong foundation upon which other 声 can be built and 加

They provide a 固定 point of reference against which other 声 can relate without needing to enforce a 定义 音 结构

This gives 音乐家 and composers flexibility and freedom to improvise and play along over the drone

Drones and 电子 Music
电子 乐器 and 震荡器 are drone 制作 machines The pitched 音 that that 创作 are 纯/完美 for 制作 drone 樂/乐

As synthesisers and drone 制作 电子 became more available in the 1970s a whole 波 of composers began to 创作 drone 樂/乐 from 电子 声

These 作品 used 延（续） 电子 音 which interacted and complemented one another These 声 would modulate one another and 创作 复杂 声波 波 interactions

创作 Drones
We know that drones can be 创作 using certain 乐器 and by 震荡器 and 电子 乐器 but drones can also be 创作 by 编辑 声波 files

If we 用 time-stretch to really extend a 声波 it looses its 包络 and begins to turn into a 'drone like' 声波

The more we stretch the 声波 the more 'drone like' it becomes

By stretching different short 声 we can 创作 an array of drone 质地（纹理、织体） that can be 合并 to make a drone 作品

Filtering 延迟 and 混响 can also be used to sculpts and modify the 品质 of these 声 blending them together
