    Press NEWYORK TIMES(October 16, 2000) (thanks to Mr. Masui@a research engineer of Fujitsu Labs., Dr. J.Downie@Univ of Illinois, Mr. Craig@Nevill-Manning).
    History In 1997.4, I, Tomo. Sonoda,  began to develop our system for a thesis at my university (WASEDA). The first concept of this system is for retrieving a melody by singing on mobile phones or for using at music shops.

    Mr. Kaizuka, who belongs to Fujitsu now, was the first person in our laboratory and he developed a melody retrieval system by using pitch and vowel of musical notes (1996-1997).
    We (Prof. Dr. Yoichi Muraoka, Dr. Masataka Goto and I) developed another system which used pitch and span of notes for retrieving.

    In 1997.8, we finished to develop our proto type system.
    In 1998.3, I start to apply patents to U.S., E.P.O and Japan for building a venture  company.
    In 1998-2000, we attended several international conferences and made oral presentations.

    Jan. 4th, 2001, we established 'utagoe co., ltd' for the melody retrieval service by singing.
