Patent number: 6252152Abstract: Automatic composition apparatus and method is able to automatically compose a piece of music having a melody that is favorable in a musical sense, namely, a melody that satisfies musical requirements. A storage medium stores a program executed for automatically composing a piece of music having such a melody as described above. After melody pitches are generated under moderate first melody generation conditions, the generated melody pitches are evaluated in terms of more strict second melody generation conditions. With regard to a certain pitch, therefore, it can be determined whether the pitch satisfies musical requirements in view of not only the previous pitch but also the next pitch, thus making it possible to compose a piece of music that as a whole is favorable in a musical sense.Type: GrantFiled: September 9, 1999Date of Patent: June 26, 2001Assignee: Yamaha CorporationInventors: Eiichiro Aoki, Toshio Sugiura

Patent number: 6080926Abstract: In an automatic accompanying apparatus and an automatic accompanying method, the respective part structures of a plurality of basic variation patterns used as a basic accompanying pattern of rhythm are arbitrarily set by a music player. When the music player selects one basic variation pattern from a plurality of basic variation patterns to which the part structures are set in such a manner, the part structure is automatically set in such a manner that part structures of an intro-pattern, an ending pattern, and also a fill-in pattern, which are prepared for this rhythm, are made equal to the part structure of the selected basic variation pattern. The automatic accompaniment is carried out by employing the selected basic variation pattern, and the intro-pattern, ending pattern, and fill-in pattern, which own the same part structures as that of this basic variation pattern. As a result, the automatic accompaniment can be carried out while being matched with a motif of a user through the entire music.Type: GrantFiled: May 25, 1999Date of Patent: June 27, 2000Assignee: Kabushiki Kaisha Kawai Gakki SeisakushoInventor: Toshinori Matsuda

Patent number: 5895878Abstract: In a music apparatus, an operator panel designates a first style of automatic play. A tone generator sequentially generates musical tones to produce the automatic play in the designated first style. A DSP applies a first effect to the musical tones in matching with the first style of the automatic play. A CPU operates when the operator panel commands a style change from the first style to a second style during the course of the automatic play for controlling the tone generator to switch the automatic play to the second style. The CPU further operates when the style change necessitates an effect change from the first effect to a second effect matching the second style in a transient period for controlling the DSP before the controlling of the tone generator to complete the effect change within the transient period so that the DSP can apply the second effect to the musical tones timely when the automatic play is switched from the first style to the second style.Type: GrantFiled: December 31, 1997Date of Patent: April 20, 1999Assignee: Yamaha CorporationInventor: Masao Ishibashi

Patent number: 5744744Abstract: An electric stringed instrument having an integral accompaniment system is proposed. The vibrations of the strings on the electric stringed instrument are detected as analog signals by a pickup device. A portion of the detected signal is extracted, has its voltage adjusted, is converted into a digital signal, and is read into a CPU as a digital signal within a range of 0-5 volts. An amplification factor of the digital signal is determined according to sound volume data included in accompaniment data stored within the accompaniment system, and the proportion of sound volume between the player's performance and an automatically generated accompaniment is adjusted by multiplying the sound volume of the player's performance, or of the accompaniment, by the amplification factor. The sound volume adjustment is effected only once and only when an automatic balancing switch provided on the instrument is depressed.Type: GrantFiled: October 24, 1994Date of Patent: April 28, 1998Assignee: Kabushiki Kaisha Kawai Gakki SeisakushoInventor: Sadamoto Wakuda

Patent number: 5510572Abstract: A melody segmentation module segments a given melody into a plurality of phrases. A phrase tonality analyzer determines a key of each phrase to provide a correct succession of keys of the melody. With this arrangement, the music apparatus can detect, from the melody, a modulation (change of key). A chord progression database is searched to assign an appropriate chord pattern to each phrase. Thus, the melody is harmonized with a natural and real chord progression. A style analyzer tests a melody phrase for a preselected music style and labels it with style-matched if it meets the preselected music style. A chord pattern characteristic of the preselected music style is selected from a chord progression database of the same music style to harmonize the style-matched phrase. Thus, the melody agrees with the harmonizing chord progression in terms of music style.Type: GrantFiled: October 8, 1993Date of Patent: April 23, 1996Assignee: Casio Computer Co., Ltd.Inventors: Tetsuya Hayashi, Kunihiro Matsubara
