Forest of Piano or Piano no Mori is based on a 2007 animation film also called Piano no Mori. I haven't watched the film but, based on the images I saw, I can tell the first season of the anime covers the story in the movie and the second season expands it. In the first part we watch Kai Ichinose difficult childhood, his connection with the piano in the forest and the beginning of his relashionship with Shuhei Amamiya. It's a simple yet captivating coming-of-age story, with a nice character development and a good narrative. Kai is very likeable and I couldn't help but be curious to know what was going to happen in his life, so I went straight to season 2. There are some differences regarding the two parts. The second has much more music and more characters. If you like piano and erudite music, then you are gonna enjoy this part a lot. It's delightful to watch and, essentialy, to hear the pianists through the 12 episodes of the season, the same amount of season 1. I can't say much about the second phase, cause it would be a spoiler so I'll just say it focuses on a very famous pianist from the romantic era and it's lovely to see the amount of love people from the country where he was born still gives him, through events. Like I said before, there are more characters in this season, what adds a lot to the narrative, that becomes more complex, with more conflicts. There is just one negative thing I gotta highlight in this review: the animation. The drawing is beautiful, but it lacks in motion. In the first season the animators used techniques to give motion to the characters while playing the piano, so it's delightful to watch and hear the piano. But, regarding season 2, there is almost no movement at all, therefore, it relies totally in the beautiful soundtrack. Like I said in the trivia, professional pianists were hired to play for the studio. I don't know so much about music yet I could totally notice the difference in the way each character plays the piano. It's a masterful job. That's why it's crucial to like erudite music to watch this anime, because it's what stands out in it. I loved the music, the landscapes and the energy about the city so much that it became a dream of mine to go there someday and pay homage to the brilliant composer the anime honors.
