There are many types of whistle, those you can make with your fingers, with your hands, wolf whistles and even whistles using a blade of grass. You can even sing and whistle or hum and whistle at the same time. There are two kinds of whistle you can make with just your mouth, the Pucker Whistle and the Palate Whistle. Some people have a hard time making a whistle noise, but if you practice and follow the instructions in this Wiki How you’ll be whistling in no time.
口哨有多种，有用手指或手[可能指手埙类]配合吹的，还有用草[我国古今以树为常见]叶片吹的。你可以边唱边吹[这是一个人不可能同时做的，应该是一会儿唱一会儿吹]，或者边哼边吹[类似呼麦]。有两种口哨不需要其他辅助，而只用到口腔，分别称为唇（撅嘴）哨和上颚（即展唇）哨。有些人觉得口哨发声很难，但只要你按照下面“维基释疑”所提示的练习，很快就能吹出声音了。
Steps [edit]步骤
Whistle with your lips: The Pucker Whistle 唇哨：撅嘴哨
Pucker up. 噘嘴
Try saying the word “ooh” to get the right shape in your lips. You want to create a tiny O shape with your lips.
试着发“呜[舌位靠后，汉语“ü迂”更接近，但英语没有这个音]”音找到正确的嘴形，形成一个小O的形状。
Make your tongue taut and push it into your lower gum.
舌头绷紧[下贴]，伸向下齿龈。
It does not have to be touching the gum or teeth.
舌头不必碰到齿龈或牙齿。
If done correctly, your tongue will make a curved shape, almost like an airplane wing.
做得好的话，舌头会形成一个机翼似的弧形[即舌面成U形]。
Blow air from your diaphragm out through your lips.
从胸膈膜处[这是强调胸腹联合呼吸，这对演奏重要，初学发音不必]发气吹向唇部。
Don’t blow hard, just softly at first.
开始不要用力，只轻轻地吹。
Some people prefer to inhale rather than exhale.
有些人更喜欢通过吸气发声而不是吹气发声[一般、最好以吹为主，说另详]。
Adjust the position of your tongue and the shape of your lips until you find a note.
调整舌位和唇型直至发出声音。
Experiment with the position of your tongue (either near the roof of your mouth, or behind your bottom teeth works well) and also with the positioning of your lips (try puckering them further).
试着调整舌位（将舌头或靠近上颚或靠近齿后）和唇型（如撅得更向前些），以发出不同的音。
Whistle with your mouth: The Palate Whistle
用口腔吹：上颚[即展唇]哨
Understand that this whistle takes strength in your tongue, jaw and other parts of your mouth and so may take some practice and exercise.
这种口哨要用到舌头、上下颌等口腔多个部位的力量，所以可能需要多加练习。
Draw your lips, the corners of your mouth, as far back as you can. Your bottom teeth should not be visible, but it is OK if your top teeth show.
拉平嘴唇，让嘴角尽量向后。不要露出下齿，而上齿可自然露出。
Pull the tongue taut: draw it back.
舌头向后绷紧：即向后拉。
Broaden and flatten the tip of the tongue.
平展舌尖。
Be sure there is a space between your teeth and tongue.
确保在[上]牙齿和舌头之间留出空隙。
Your tongue should float in your mouth more or less at the level of your bottom row of teeth.
舌面应与下齿上端基本平齐。
Blow air gently out.
轻柔地吹气。
Direct your breath downwards towards your lower teeth. You should be able to feel the downward force of the air on your tongue.
将气引向下齿，要能够在舌面上感觉到向下的气流。
The sound is created by the tongue working with the upper teeth to force air over the surface of the tongue and into the lower teeth.
通过舌面与上齿共同作用强迫气流略过舌面，气流在进入下齿后面时发出声音。
Experiment with the position of your tongue, cheek muscles, jaw and anything else for a wide variety of whistle sounds.
试着调整舌位、面部肌肉、上下颌和其他部位可以吹出相当丰富的哨音。
Tips [edit]
小窍门
If the above steps don’t work, try saying the initial ‘ooh’ in a number of different ways.
如果上述步骤不管用，尝试着用不同的方式发出一开始练习的“呜”音以找对口型。
Different notes are produced through very slight changes in the position of your tongue and jaw. Don’t move your lips.
不同的音是通过舌头和上下颌的微小变动而发出的，但嘴唇不要动。
It might also help to make your lips moist
把嘴唇弄湿可能会有点帮助。
When you exhale try to raise your diaphragm so that your air escapes in a slightly raised direction.
吹气时努力提升隔膜，让空气从略高鼓的隔膜上发出[这是强调胸腹联合呼吸，这对演奏重要，初学发音不必]。
Every whistle has a “sweet spot” where the shape is correct for a long, clear tone. Practice with the above whistles until you find your sweet spot.
每个哨音都有一个“绝妙点”，即能够发出悠长、清晰音调的口型。一个音、一个音地练习，找到每个音的最佳点。
Do not force the air out of your lungs when you exhale. Instead, release your tightened lungs, and simply let the air flow out. Once you’ve learned the basic pucker, you can begin to exhale in order to control the duration and volume of each note you whistle.
呼气时不要用力将空气从肺部压迫出来，而是要放松肺部，轻松地让空气流出。一旦学会了基本的撅嘴动作，就可以开始呼气，控制住每个吹出的哨音的持续时间和音量。
Don’t blow hard, especially when practicing. This will give you more air to practice with and it is better to get the sound and shape before going for volume.
不能用力猛吹，特别是练习时不要这样做，不然就需要更多的气来练习。在追求音量前最好先找准音和口型。
Warnings [edit]
注意事项
If you find you can whistle really loud, refrain from doing so in someone’s ear. It generally is not appreciated, because it tends to hurt.
如果你真地能大声吹了，千万不要对着人的耳朵吹，那样会惹人讨厌，也可能伤到耳朵。
Sometimes you may find yourself short of breath after whistling loudly or for a long time.
吹口哨声音太大或时间太长你可能会觉得喘不过气来。
You may feel weezy after whistling/practising for too long
吹口哨或练习时间太长会觉得气短。
