1-Hello everyone.
Today, I want to talk to you about The Korean traditional music, Samulnori.
Before talking about samulnori, let me introduce South Korea.
South Korea is located in Northeast Asia. It is surrounded by China on the left and Japan on the right.

(PS: you better have a map projected on the board or it might sound weird) 

2-The official name of South Korea is the Republic of Korea in English. Korea has many features. For the sake of clarity, let me break these features down into 4 aspects; Population, National Flag, Climate and National Flower. The population of the Korea is 50 million and the National Flag is Tae-guk-ki. Also, Korea has 4 distinct seasons which are spring, summer, fall and winter. Perhaps, for foreigners who live in areas that do not have such different seasons, it is hard for them to get through this climate. Finally, the National Flower of the Korea is Hibiscus Syriacus, also called The rose of Sharon.

3- Now, let us talk about Samulnori. Samulnori came from Pungmulnori, which is a traditional agriculture performance with instruments. The tune of samulnori is taken from the tune of pungmulnori. It all started with Kim-duk-su (this man in the picture), he is the center of Samulnori 'pae' in 1978. (In English, 'Pae' is 'Band'). And, samulnori is a chamber music. So unlike pungmulnori that is supposed to be played with dancing, musicians are supposed to play music on stage.

4- Musical instruments of Samulnori are 4. It consists of large and small gongs, small drums, barrel drums and hourglass drums. The small gong is called kkwaenggwari, the large one is Jing, the barrel drum is buk, and the hourglass drum is called Janggoo

5- These instruments are connected with nature. Kkwaenggwari echoes thunder, Jing reflects the wind, buk represents the clouds, and janggoo takes after the rain. These things connect the harmony of yin and yang. kkwaenggwari and Jing connects to "yang" which indicates the sky. Their sounds go around  and float in the air. And buk and janggoo connects to "yin" which indicates the earth. Their sounds go ringing through the earth. Therfore, this harmony between the sky and the earth makes samulnori musically great.
-Thank you for listening.

Q-what is the yin and yang? - yin and yang is an eastern philosophical idea. It identify how seemingly opposite or contrary forces are interdependent in the natural world. For example, plus and minus , man and woman, sun and moon, sky and earth, etc.

-------------------

words in red: these are grammar/spelling mistakes

words in green: suggestion to improve the quality of your writing.

words which are highlighted: they are the "phrasal verbs" in the text.

the definition of yin and yang is edited from wikipedia.

maybe there are few more mistakes, but then again no one is perfect!

great work over all.
