This piece of music is relaxing and calming. I think that's all thanks to the fact, that tunes are seemingly similar cause they have little difference from each other. It feels like ascending and descending a mountain, it's gradual, soothing and steady. Sometimes I feel imperfection is much more better than perfection, that's because imperfection leaves room for improvements. As opposed to being perfect, you lose sight of your "path" moving forward, there you will be at a standstill at the pinnacle and don't know where to go. That eventually becomes stagnation which is akin to regression, that simply means you hit a wall and don't know how to overcome it, alas, an insurmountable obstacle. Therefore, in this case, imperfection is much more better than perfection.
Oh yeah, this is my opinion and it is subjective, biased and abstract. Have a nice day and bye guys!
