【口琴汇--搬运经典】Comprehensive guide totheCornerswitchingtechniqueVIII
原文的全部标题是：
Comprehensive guide to the Corner (or Tongue) switching technique
--by M.A. Weber
Corner switching is one of the most intriguing and important (but unfortunately also underrated) techniques to master on the harmonica.
There is quite an amount of frustration and practice required to fully grasp this technique but at the end it is all worth it.
Alan “Blackie” Schackner uses a very appropriate analogy in his book “Everything you always wanted to ask about the chromatic harmonica but didn’t know who to ask!“:
拐角切换是口琴上最引人入胜和最重要（但不幸的是也被低估了）的技巧之一。
要完全掌握这种技巧，需要相当多的挫折和练习，但最后都是值得的。
Alan "Blackie "Schackner在他的书中用了一个非常恰当的比喻 "一切你一直想问的关于半音阶口琴的问题，但不知道该问谁！"。
Also, John Sebastian Sr. wrote about it in his “Classical Harmonica Series” books (1-6):
另外，老约翰-塞巴斯蒂安在他的 "古典口琴系列 "书籍（1-6）中也写到了这一点。
ohn Sebastian, classical harmonica music series
John Sebastian Sr. describes the technique as right and left tongue blocking.
Well known harmonica soloists, like Cham-Ber Huang were big proponents of the technique and used it frequently. In the book “Harmonicas, Harps and Heavy Breathers: The Evolution of the People’s Instrument“, the Author Kim Field wrote:
“Cham-Ber Huang trying to explain the intricacies of tongue switching to me while rocketing us down the Long Island Expressway in his car”
His student Robert Bonfiglio can be seen in the following video giving a good practical insight of the technique:
老约翰-塞巴斯蒂安将这一技巧描述为左右舌封锁。
著名的口琴独奏家，如黄湛伯就是这种技巧的忠实拥护者，并经常使用。在《口琴、竖琴和重呼吸者。The Evolution of the People's Instrument "一书中，作者Kim Field写道：
"黄昌伯试图向我解释舌头转换的复杂性 当我们开着他的车在长岛高速公路上飞驰时"
他的学生Robert Bonfiglio可以在下面的视频中看到他对该技术有很好的实际见解。
During this course I will point out some of the advantages of the technique, visualized by my proposed exercises.
Note: this course focuses on using a 3 octave chromatic harmonica. I am sure a lot of the below exercises can be repurposed to be used for a 4 octave chromatic or even partially for a diatonic harmonica.
It is important to understand that in order to master the corner switching technique one needs to be able to play equally well from both corners of the mouth using tongue blocking. That means, at least at the beginning of the process more practice will be needed to master musical passages equally well playing with the right and left corner.

Exercise VII – Real world classical music examples
Exercise VIII – Complete example to analyze
Final Words
在本课程中，我将指出该技术的一些优点，通过我提出的练习直观地表现出来。
注意：本课程的重点是使用3个八度的半音口琴。我相信下面的很多练习都可以转用于4个八度的半音阶口琴，甚至部分用于双音阶口琴。
重要的是要明白，为了掌握转角技术，需要能够用舌头阻挡从两个嘴角同样弹好。也就是说，至少在开始的时候需要多加练习，才能掌握用左右嘴角同样演奏好的音乐段落。

Exercise VIII
Complete example to analyze
This is the final piece of music for you to study. It has all the possible combinations of right and left corner switching over octaves as well as NCCS.
I transcribed that solo some time ago. McCoy Tyner is the soloist (sadly, he passed away this year – RIP). He is one of my favorite pianists and this is one my all time favorite solos. It is from the album “The real McCoy“.
This is one of the hardest pieces I ever played. Using corner switching made the job a little easier. You can hear the result in the recording I added at the bottom. There, I also attached the pdf version of my transcription to download.
这是供你学习的最后一首乐曲。它有所有可能的八度以上的左右角切换组合，以及NCCS。
我在一段时间前转录了这段独奏。麦考伊-泰纳是独奏者（不幸的是，他今年去世了--RIP）。他是我最喜欢的钢琴家之一，这是我一直以来最喜欢的独奏之一。它出自专辑《真正的麦考伊》。
这是我弹过的最难的作品之一。使用转角开关使工作变得容易一些。你可以在我添加在底部的录音中听到结果。在那里，我还附上了我的转录的pdf版本供下载。
Final words
This is the end of the tutorial.
I hope you enjoyed the exercises and can start to integrate corner switching into your harmonica playing. I also hope the exercises are structured enough to build up your skills. I am happy to share my knowledge with you. I would be glad for any feedback. You can write a reply below the pages.
Pretty early, I started to integrate the corner switching technique into my harmonica playing. But only in a very superficial manner.
I was mostly relying on the right corner. Only for bigger jumps I briefly switched to the left corner and then right back to my more comfortable right corner.
After years, I took it on me to force myself practicing only playing with the left corner until I felt really comfortable. It still took more time to finally incorporate the switching into my soloing.
Now that I internalized the technique it opens up new possibilities in my playing.
The flow of the music feels more natural since intervals do not interrupt the movement of the musical lines.
Don’t be discouraged at the beginning of your journey. It will get better every day and will be rewarding.
Happy harping!
Some info off topic:
I created a blog about the chromatic harmonica history. In 43 chronologically ordered articles I wrote about a wide variety of different chromatic harmonicas. Please be invited to check it out:
这就是本教程的结束。
我希望你喜欢这些练习，并能开始将角的转换融入你的口琴演奏。我也希望这些练习有足够的结构性，以培养你的技能。我很高兴能与你分享我的知识。我很高兴得到任何反馈。你可以在页面下方写下回复。
很早以前，我就开始把转角的技巧融入我的口琴演奏中。但只是非常肤浅的方式。
我主要是依靠右角。只有在较大的跳跃时，我才会短暂地换到左角，然后又马上回到我更舒服的右角。
几年后，我强迫自己只用左角来练习，直到我感到真正的舒适。我还是花了更多的时间才最终将这种转换纳入我的独奏中。
现在我已经把这个技术内化了，它为我的演奏提供了新的可能性。
由于音程没有打断音乐线条的运动，音乐的流动感觉更加自然。
在你的旅程开始时不要灰心。它每天都会变得更好，而且会有收获的。
快乐的竖琴!
