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.

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。
