This is a piano solo piece by a composer, Hiroki Saitoh. Warm and light-hearted. With this song I tried to portray a sense of delight, a little happiness and joy of our daily life. The melody flows like a gentle breeze with soft piano tones, embracing people, reminding them the beauty of nature. A bouncy rhythmic part in the second half expresses the feeling of dancing with joy. The best moment in this world for me is when I see the smiles of whom I love. Listening to this song, I want everyone to feel such calm and dear moments of daily life. So, I put these feelings into the title 'Smile'. I hope this song will make as many of you and your beloved people as possible feel warm with a smile.
