In 音乐 an adjective referring to 和声 and its 原则 In 声学 when a 颤 对象 such as a string is set in 运动 it vibrates both as a whole with a 频率 called the 基（础） and with lesser 强度 in 片段 as well If these smaller lengths are 整数 fractions 1/2 1/3 1/4 of the 总 长度 of the string their 频率 of 振荡 are called 谐波（泛音） and are 整数 倍数 of the 基（础）

Other resonating 频率 which are 不 whole 倍数 of the 基（础） may also be present and are called 分音 Bells for instance have many 分音 in their 频谱 more than 弦（乐） or pipes It is the 临场 and 相对 strengths of 谐波（泛音） and 分音 in a 频谱 that are largely responsible for the 音 品质 音色 of any sound-producing body

音符 In some texts the 术语 'partial' 提及 to both 谐波（泛音） and 非和谐 resonating 频率 In other 词 all 谐波（泛音） are then 分音 but 不 all 分音 are 谐波（泛音） 泛音 is often used to designate both 谐波（泛音） and 分音

The 谐波（泛音） 生成 by a 颤 body if they are 整数 倍数 of the 基（础） may be represented in an ordered 系列 called the 谐波（泛音） 系列 源 Barry Truax - Handbook for Acoustic 生态学 CD-ROM Edition Cambridge Street 出版 1999 - CSR-CDR 9901
