Answer:

1. Historically, Japanese folk music was strongly influenced by music from China, with some of its forms being imported from China more than a thousand years ago. Many popular Japanese musical instruments originated in China and were then adapted to meet local needs.
2. The music often looks to represent natural sounds, and the sounds of life, through percussion, wind and stringed instruments. An interesting feature of classical Japanese music is its sparse rhythm and absence of regular chords. All of the rhythms are 'ma'-based and silence is an important part of the songs.
