I am interested in musical instruments for a long time. Before being interested in Asia, I have learnt variously musical instruments of the West.
After starting to visit Asia, I was interested in musical instruments of Asia. At first I searched for the length whistle in Vietnam. Finally I found it but I couldn't get it because the price was quite high.
In Thailand I was not interested in musical instruments so much. However, after I came to be interested in Mo Lam, I was interested in musical instruments again.
It is Kaen. Mo Lam seems not to consist without this.

Well, it doesn't go well easily though I wanted to get Kaen. To begin with, the shop that sold a Kaen could not be found. I asked some Thai people where I could buy a Kaen. Then their answer were like, one of my friend in the country has a Kaen, or my cousin performs Kaen well. It doesn't serve as a reference so much. So it was in pending status for a long time.
After a few years, during staying in Vientine, when I browsed a guidebook I found the article that showed how to buy a Kaen in Vientine. At that moment I recognized it is the chance. However also I knew these informations sometimes contained error in writing. So I tried to find the craft center in half believing. Sure enough some of the detail information were wrong but finally I could reach the craft center. And I dealed with the wife of the master. And I was successful in getting the Kaen for me. (Recently there appeaed a sign in the street, So now it is easy to reach the craft center.)
During moving to Thai from Laos, the custome officer of Laos and the airport bus driver tryed playing this Kaen :-) Both of them said this was a quite good Kaen. So the problem that remains to be solved is how to learn playng the Kaen.
