Dear Mr. Friedland,
尊敬的弗莱德兰先生：
I am writing to you to seek for help and advices again.
再一次致信打扰您，期待得到您的指点。
As a band student, we some time may encounter some jazz style music, mostly by the Japanese. So I think it would be nice if I could use some jazz techniques.
作为一个乐队成员，我们有时会遇到一些爵士风格的作品，大多数是日本的。我认为如果能用上一些爵士演奏技巧，或许有助于增强表现。
Firstly, I would like to know how to create that kind of humoring pitches that the music requires. Then, is how to do a proper glissando, do I need to move my jaw inward/outward to do a glissando?
首先，我想知道应该怎样发出那种爵士乐常有的幽默的音调。然后就是怎样正确的演奏滑音，我需要将嘴唇内外移动来制造这个效果吗？
Lastly, I am playing double-lip; do I have to switch to single-lip to play jazz style?
最后，我是用双包嘴型演奏，我需要改成单包演奏爵士吗？
Thank you very much.
非常感谢！
Regard, Wu
吴 敬上

Hi Wu:
你好，吴：
Very important, you do not have to change your embouchure to single lip in order to play in the jazz style. And you simply just continue to do your regular so-called Classical training. Benny Goodman was a classically trained clarinetist. So too were most of the Jazz Artists.
非常重要的一点：你无需改成单包来演奏爵士，同时你也只需要继续按照古典音乐的演奏训练即可，并不妨碍你演奏爵士。Benny Goodman就是一个演奏古典音乐出身的单簧管演奏家，正如大多数爵士艺术家一样。
Clarinet technic is very basic, and is the same for all styles of music.
单簧管的技巧是很基本的，而且适用于各种风格的音乐。
And the best way to learn to play jazz is to listen to jazz recordings of all the jazz clarinetists you can find. Simply copy their playing and their particular stylistic ideas.
学习爵士最简单的办法是尽可能多听爵士单簧管演奏家的录音，学习他们的演奏方式和演奏风格。
Do not change your embouchure or anything. You must listen all of the time and at first emulate your jazz recordings, and soon you will arrive at your own style.
不要改变你的口型或者其它什么。你首先需要去听、去模仿，然后才去找自己的风格。
best wishes 祝你好运
Sherman Friedland
