一年里,r/singing 上七个互不相干的帖子在问同一件事

一年里,r/singing 上七个互不相干的帖子在问同一件事:没有老师的时候,一首歌的和声声部要怎么学?答案清一色是「多练」。提问的人分别是四个孩子的妈妈、社区剧团的导演、乐队里唱和声的鼓手,而他们描述的失败一模一样:唱着唱着就滑回主旋律。

Q:这条到底是什么?

选你真正想唱的那首歌。拿回属于你的那条声部——一条可以单曲循环的引导音轨,外加一面练习镜子,把你嗓子塌回主旋律的那几秒标出来。

Q:他为什么非要用不可?

提问的人不是在挑工具的音乐人。是四个孩子在家想合唱、一离开合唱团就卡住的妈妈;是手下女中音守不住声部的剧团导演;是乐队需要他唱和声的鼓手。他拿到的是自己的那条线——单独听得见,也改得动。

Q:今天缺的到底是什么?

现存的东西只有两类:抽象音程耳训(Perfect Ear、Functional Ear Trainer),和对着主唱打分(Smule、Yousician)。没有一个针对你眼前这首歌给出你的那条声部,也没有一个抓得住每个提问者都在说的同一个失败:滑回主旋律。

Q:这一刀切在哪里?

别做一个唱歌 App。做一首歌的一条线:20 首公版与常见合唱曲、只做三度上方、一条单独的引导音轨、外加你跑掉那几秒上的一道红线。冷启动第一步:中文=小红书/B站「和声怎么唱」「合唱 声部 跑调」标签下的评论区与合唱团家长群;英文=r/singing 那七个求助帖本身就是一份已经举了手的名单,再加社区音乐剧团与教会诗班。

Q:它最锋利的地方在哪?

生成录音里根本不存在的一条声部——在这个调、这套和弦上、一条唱得出来的三度——需要在任意复音音频上做和弦识别,再走一遍声部进行。分离与复音转谱是最近两年才变成日用品的。至于「滑回主旋律」的检测,不过是两条音高曲线的实时比对。

Q:什么会杀死它?

和声不是一件事——「三度上方」经常就是错音,一条站得住的声部要看和弦、看排列、看曲风。做错了,就是教一个人把错音唱得很自信,比什么都不做更糟。受众也是热情但小(这些帖子是 5–20 分,不是几千分),商用录音的权利问题会把云端版本推进授权泥潭,而本机版本没有这个问题。

Q:谁付钱,付的是什么?

已经在为孩子的合唱团付钱的家长,或者已经在按月上声乐课的成年业余爱好者——定价对标一节课。

Q:最大的风险是什么?

生成声部的音乐质量就是产品本身,错的一条比没有更糟;商用录音的权利会把真正好用的那版推到用户自己的设备上。

Q:真人原话是怎么说的?

以下原声逐字摘自公开来源,未经改写: “Most of the time when I try to it's okay for the first couple notes before I end up drifting to the main melody line or ending up somewhere in the middle (and it sounds and feels awful xP).” — reddit r/singing (18 pts / 23 comments) “feels like no matter what i try i can't pick it up, no tutorials so far have helped and i spent basically a year trying to find the harmony when i was singing along to music and just couldn't get it” — reddit r/singing (23 comments) “there's no easy way to learn harmonies to new songs without that guidance. How do you currently learn harmonies when there's no teacher around? Is there an app for this?” — reddit r/singing — mother of four “I have a cast member (a beautiful alto) who is struggling to hold harmonies when singing with others, and has asked for some resources/tips/etc. Problem is, I don't have the answers!” — reddit r/singing — theatre director (13 pts / 15 comments) “My band NEEDS me to be able to sing for harmonies, but I just cant. What do I even do?” — reddit r/singing “When I hear a melody I can sing harmonic over that one. But when I do the same over a song that already has a singers voice in it I, often sing disharmonious.” — reddit r/singing (8 pts / 9 comments)

Q:要做多久?

两个月左右的工作量
