Wada Kaoru can be said to be the representative of the young school of Japanese animation music. Kaoru Wada was born in Shimonoseki City, Yamaguchi Prefecture, Japan in 1962. He began to teach himself composition and harmony at the age of 17. After winning some minor awards, he entered the Tokyo University of Music in 1981 and studied composition with Ifukube Showa and Ikeno Shigeji. He studied conducting under Ze Anyan. After graduation, he lived in Europe, where he observed the activities and operations of symphony orchestras in several countries. In 1985, Wada began to get in touch with electronic music and bands. A year later, Kaoru Wada went to Europe, the holy land of music, to study and exchange. He held many successful concerts in Amsterdam and other places. Later, he performed in North America and received unanimous praise. By 1988, the overture of his work "Folkloric Dance Suite for Orchestra" was performed in Sweden by the Malmo Symphony Orchestra, and was subsequently performed in the Netherlands, France, the United Kingdom, Switzerland, Spain, and Germany. , Denmark, Norway, the United States and Japan and other countries, and was released in Germany in 1990. After returning to Japan, Wada Kaoru devoted himself to the production of film music and animation music. He founded the "Wada Music Office" in 1989 and began composing music for movies, TV animations, etc., and served as the planner, composition and composer for the Rising Star Japan Symphony Orchestra. He has extensive attainments in folk music and other fields. In terms of animation, in addition to "Inuyasha", he has scored music for well-known Japanese animations such as "Three Eyes", "Saint Seiya", "Mekhan Corps", "New Vampire Princess Miyu". Kaoru Wada's soundtrack style is sonorous and passionate, and clearly belongs to the orthodox school. It mostly uses horns, orchestral instruments and other instruments to express the majestic and high-spirited heroic spirit. The music for tense moments often uses exciting violin vibrato, irregular drum beats, deep horns to slowly repeat a tune at different scales, or a bee-like chaos, and the soundtrack effect achieved in this way is quite good. In addition, the soothing part of his score is also quite good, simple and fantasy-like. Compared to Kanno Yoko, a composer who is good at collecting materials from folk music from all over the world, Wada Kaoru prefers traditional music, with Oriental Xiao , flute, taiko drum, and erhu can all find space in his music. For example, in the soundtrack of "InuYasha", he made full use of these instruments, giving the music of "InuYasha" a unique Japanese classical charm. The story of "Inuyasha" is mainly composed of two main lines intertwined with each other to form the basic plot. One is the search for the Jade of the Four Souls, and the other is the emotional entanglement between Inuyasha, Kikyo, and Kagome. And this is also reflected in the soundtrack of "Inuyasha". The first main line follows a boy anime-style passionate route, so the music related to it also maintains the sonorous and exciting style of Rhode Island. The use of a large number of wind instruments makes people feel more passionate, and Japanese traditional musical instruments are occasionally interspersed. This passion brings a bit of shadow and uneasiness, hinting at various dangers on their way forward. Since the second main line is mainly about emotions, although it also features wind instruments and has many parts with a brisk rhythm, it is handled in a relatively calm and soothing manner. In addition, the addition of human voices and traditional musical instruments such as bamboo flutes and erhu not only express their emotional entanglements that are constantly being sorted out, but also echo the bitter mood of the three protagonists in this love triangle. It can be said that in order to match the two main lines of "Inuyasha", which are "hard" and "soft", Kaoru Wada also worked hard to make the soundtrack "hard and soft".
