欢音 苦音  中国西北及陕西省关中地区戏曲和民间音乐中普遍应用的音乐术语。由两种不同的音阶与调式所形成,作为表现感情气质变化的技法之一。在秦腔称为欢音、苦音,或花音、哭音,眉户称硬调、软调,碗碗腔称花音子、苦音子,四川弹戏称甜皮、苦皮,或甜品、苦品。    欢音的曲调为徵调式,其旋律常用音为sol、la、do,re 、mi五音,一般用以表现愉快、明朗、活泼、矫健等情绪。苦音的情况较为复杂,虽仍以徵音为其曲调主音,但旋律常用音则为 sol、si、do、re、fa五音,因而色彩大异。对此,国内有两种不同观点,一种认为苦音仍属徵调式,因其si音在实际运用时,习惯上略低于本律,故属于一种特殊的音阶结构的徵调式。另一种观点则认为,从实际效果看,苦音又具有 sol商调式的因素。苦音在情感气质上,有伤感、晦暗、悲愁、哀怨等感觉。有时,因低于本律的si音在旋律中甚为活跃,实际已起着宫音作用,已暂时移宫到下方大二度的调上,而构成sol羽调式。这种移宫换调的方法,在古代称为"以闰为宫"(闰即降si音)。这种七声音阶的移宫法,古代又称为"改柱换调"(柱即今日琵琶的"相")。近代学者有人认为,它与隋唐时代从西域传来的"燕乐"有密切关系,虽与汉族音乐逐步融合,却仍保留了"燕乐"的某些因素。    苦音与欢音均可独立运用,也可互相作大段转换,以适应不同感情的表现。这种技巧,在同州梆子、蒲州梆子、阿宫腔、弦板腔、线腔、老腔、陕北道情、青海平弦、青海花儿、甘肃河西曲子......均有所见,各剧种、曲种的音乐基本材料和音调虽不同,其技巧手法却相同。    以陕西眉户的"月调"为例,可看出在音乐材料基本相同的情况下,欢音与苦音的变异。    此外,粤剧的"乙反"及潮剧的"轻三六"、"重三六"、"活三五",与欢音、苦音的性质基本相同。
