Since I was a student, I have loved the singing of the University of Helsinki Male Voice Choir (Ylioppilaskunnan Laulajat) in Finland.
Their clear harmonies and unique sense of rhythm are very attractive.
This voice is something that Japanese choirs do not have. Why are they able to perform such harmonies?
I visited Helsinki in 2005 (winter) and 2009 (summer) to find out.
I thought, "Why can they play this kind of harmony?" I wondered if this pure harmony was created by the local natural environment.
In fact, I visited the site, but I did not know the answer to that question.
However, when I heard the harmony of YL, the nature of Finland came to my mind.
Finland's nature is very refreshing.
I thought that this coolness created the transparent harmony.
My recommendation is ”Pohjois-Karjala” sung by YL.
You can listen to it on You Tube.
It takes about 6 minutes, but it starts to get cooler after 3 minutes in the middle.
Please listen to it when it is hot！
This is just my personal view.
