I erect a harp by the mirror lake.
In the mirror I gaze at her grace,

When autumn breeze wrinkles her face,
I hear fallen leaves pluck her string.
And see golden sun rays decorate her reflection.
Harp sings a song of mesmerizing spring,
Till I tie autumn with affection.

我自己录歌也是，那pitch就像
天上的云，到处地飘，
飘到哪里我自己也不知道。
后来有一天，我用了一个pitcher软件，
发现指针那个跳啊，才发现有太多的问题。
最令人沮丧的是，尽管问题发现了，但是
要想光靠嗓子全部修正过来有时候还是不太容易
所以说，对于pitch的修正，还需要些时间来理解。
我是等不及的，所以我现在录歌，都上pitch修正音高，
自动的不行嘛就手动调整弹性音频。反正我就靠鼠标了。 |

前面那个帖里面提到了pitch的问题。
这里也稍微提一下。
有时候低音的pitch其实挺难把握的，这时候我也没有啥好的办法，
我自己是靠修的。
在高音的pitch这个有时候要hold住，这个也挺难的。比方说一个长音
3拍，第一拍对了，但是二三拍有时候不太容易hold住。
这时候我也没有啥好的方法，我自己是把3拍长音剪开修正的。 |

发帖数: 22634 | 7 三兄，俺著名走音公鸭嗓来评论一下：
首先，很用情，这是最重要的。
然后我来拍缺点。
效果上，我觉得缺陷是有些偏音。
唱的像说话一样并不是偏音，而是一种 pitch bend。
音的主要部分跟唱一样准的，但在音头或音快结束的时
候，模仿说话那样 bend pitch。这个 bend 是相对
基准音而言的，这样造成一种说话的效果，但是音准一
样保持。
早期的一些爵士唱法，还有百老汇的一些唱法，把这种
pitch bend 发挥到极致的程度。
另外，在低音时，support 跟高音要一样，不能松掉。
这首歌低音应该还好，我也能唱这个低音。应该可以的。 |

Pitch Correction
You can check out the pitch correction by browsing these presets in

transparent or stepped and modern-sounding depending on how it’s set. A
full suite of controls allow you to adjust window size, attack time and
correction amount to tailor the correction to the performance. |

发帖数: 22634 | 10 这个真的主要音上没有明显走音，都是 pitch bend。
嗯，俺开始听错了。。。
比如我听的时候以为 57.5 秒的那个音偏低了，实际
上是起音的 pitch bend，最后结束在正确音准上，
我特别去 FFT 量了。
另外有些音准结束的时候慢慢往下掉，但起音准确，
并且在乐曲进行时有一致的 pattern，应该是风格所
用的尾音 pitch bend。 |

发帖数: 22634 | 11 我刚才用软件忙中偷闲飞速简单测两个长音。但是我说实话不想忽悠大伙儿，
俺测的都是看上去比较容易测的长音，实际上用软件测是很麻烦的，主要
比如有以下一些情况：
（1）如果跟 12-TET 差 10 cent - 15 cent，这时候要考虑是不是
平律往纯律的临时 pitch bend。这时候要看谱子调式，或者测伴奏和弦
对比。
（2）如果跟 12-TET 差 50 cent，要考虑是不是 jazz 风格的 1/4
音程的 pitch bend。
（3）如果是短音的 pitch bend，多半音准是在假想结尾处，这时候
数据量不够 FFT 不容易量准。
（4）如果是 vibrato，不用说了，FFT 测出来的能量峰值可能是两个
峰值，或者更多。加上很多 vibrato 的颤动随着拍子交替变化。测量
搞不好就是屁股决定脑袋。
所以楼上说的是对的，感觉自然就好。不过这个感觉自然里面，音准的因素
还是不小的。 |

然后关于 think high while sing low 的感觉，理论上是说
cricothyroid muscle 和 vocalis muscle 对着用力。因为
cricothyroid muscle 让 pitch 上升，vocalis muscle 如果
用力合适，应该有一定程度的让 pitch 下降的作用。如果两个

发帖数: 2328 | 19 今天去读了一些文章，总算明白你的意思了。你说的2级思维过程可能是这样的：先听
旋律，根据乐曲色彩或者尾音确定大调还是小调，再找到I Chord去确定Do的位置，这
样调子就定下来了。所以最关键还是要能听出主干音，对和弦要熟悉。你的天生音程感
知强，一下子能听出和弦，这样就确定首调了。
还看了一篇文章说，训练perfect pitch（能不能训练出来另说）是最有效最直接的识
别调子的方法。我的感觉是只要找到特征音，比如F#, C#，就能确定G, D之类的major。
还有我们说中文的，有四声，对pitch本身就比较敏感。所以大多数人听到歌词记pitch

第一， 锁定相关媒体，每个大学图书馆，尤其是新闻系里，都会有当地及周边媒体
的catalog，详细列出该媒体各个板块的编辑联系方式，和报道重点。 针对反ZD的游行
示威，首先要找主要或者有意愿报道国际新闻的媒体，联系负责国际新闻的编辑。
其次，如果所在地不是大城市如NY，则要侧重找全部local news的媒体，在这种风口浪
尖时游行反ZD，你不点明，他也知道可能会有confrontation，估计有些小地方的媒体
一年也没有这么大的热闹可以报道。比如今天去的rochester. 另外，如果你对当地电
视节目很熟悉，也可直接联系相关节目组。
平面媒体和广播电视都要找。
第二， 写pitch letter要求报道，可以发邮件，也可以打电话，但都要有个手稿，
方便说。
Pitch letter 几点技巧：
1． email的标题，能笼统就笼统，标题主要是挑起兴趣。说tibet protest，不要
提反对谁支持谁，他们想要详细信息，必须读全文，如果一上来就说我们反ZD去的，由
于不是主流媒体想要的东西，他们可能看都不看。 |
