Gosek's "Gavotte" makes me feel very relaxed and happy.
There is also Pachelbel's "Canon in D major", which makes me feel relaxed and happy.
Another comfortable song recommendation:
"Canon" by Pachelbel
(This Canon is probably the most familiar to everyone, and was later composed by George Wein It was adapted into a piano piece by Stone. It was very calm at the beginning, but I became more and more fond of it. The melodious tune is not sad, and it uses the 28-degree cycle to tell the clear sky after the rain. This is really like this. Feeling. The spotless sky after the rain, blue, distant, and pure)
"Merry Christmas Mr. Lawrence"
(It was very quiet at the beginning, and the rhythm gradually increased in the middle part. Speeding up, the intensity becomes stronger and stronger, and it ends quietly at the end, which is a very good feeling. And I recently discovered that the soundtrack for Hunan Taiwanese Zhou Bichang's courageous commercial is this song.)
"Flowing City" by Lin Hai. (The flow of the notes is very comfortable)
"Moonlight Frontier" Lin Hai
"Kiss The Rain (Yiruma)" (somewhat sad)
" Tears" (The Daydream) (The Daydream's music is always very beautiful)
"YOU&ME" (The Daydream) (Between you and me...)
"E major Etude "Farewell" Chopin (Farewell is not an end, but a new beginning.)
"Revolutionary Etude" Chopin (the second part is shocking)
"Pathétique 2nd Movement" "Beethoven (I don't feel very "pathos", but just sad and melancholy)
"Bird Poetry-AIR" piano version. I particularly like the second version.
"Castle in the Sky" Joe Hisaishi (piano version of Castle in the Sky, with an open, vast and distant feeling.)
