Description

  The present invention relates to a music playback device and a music playback method.

  Although the development of the IT industry has a great influence on music, typical examples include electronic pianos, electronic musical scores, and file-based sound sources. In this way, the encounter between IT and music has made it easy for the masses to interact with various forms of music.

  Among these, in electronic score, music is expressed in notation form, and various electronic score formats have been introduced. Such electronic musical score formats include the most commonly used MIDI (Musical Instrument Digital Interface) file format, MusicXML, MML (Music Markup Language), NIFF (Notation Interchange File DL, File Format SM). Standard Music Description Language (MNML), Musical Notification Markup Language (MNML), HTML (Music HTML), JScoreML, Xscore (extensible Score Language), and other music formats.

  However, these musical score formats are different in notation format, and the purpose of use and the degree of musical expression are different. Therefore, it is not based on the person who handles the musical score, but based on the machine on which the musical score is processed, There are limitations in the notation method of notation, analysis, search, etc., and there is a limit as a standard of electronic score format such that applicability and expandability are not expected.

  Therefore, by overcoming these limitations, there is a need for highly extensible electronic music scores that can be applied to various applications such as music notation, analysis and search, while enabling various musical expressions. Increasingly, an XML-based electronic musical score format called MusicXML has been developed to meet a variety of such requirements under the Internet environment. MusicXML is currently evaluated as the most suitable standard for electronic score format. However, since it is important to express music scores in a standardized electronic score format, when many scores in the real world are expressed as electronic scores, these scores can be played as they are. Thus, when searching for a desired score from a large number of scores, it is not based on simple keyword information such as a title or a composer, but the score management for the search based on the content of the actually expressed score is most important Is also important and necessary.

  At present, MusicXML is the closest electronic musical score format in music score expression. MusicXML is a typical music score format, and is suitable for various musical expressions by overcoming the disadvantage of being limited to the rich musical expression of the MIDI format that has been widely used so far. Since DTD is open to all, and its applicability and extensibility are excellent, it is evaluated as the most suitable standard for electronic musical score format succeeding MIDI.

  The scale sound database 200 according to the present embodiment includes twelve composition-specific programs corresponding to the compositions of the scales whose main sounds are different from each other as shown in FIG.

  Program by composition corresponds to each composition, program 1 is C major key (C major), program 2 is C # key, program 3 is D key, program 4 is D # key, program 5 is E Key, program 6 is F key, program 7 is F # key, program 8 is G key, program 9 is G # key, program 10 is A key, program 11 is A # key, program 12 Corresponds to the B key.

  Here, the main sound "de, les, mi, fa, so, la, shi, de" is expressed in Japanese as "ha, ni, ho, he, t, i, ro, ha" and in english. In other words, it is expressed by “C, D, E, F, G, A, B, C”.

  In each row of the data table shown in FIG. 7, the relationship between the scale of each composition corresponding to each composition program and the absolute scale is shown. In addition, the scale sound database 200 stores sound files related to each sound of the scale of each composition. The audio file according to the present embodiment is generated as human audio data uttered by the pronunciation of the floor name and the pitch of the floor as shown in FIG. 7, and is generated for each of the 12 programs by composition. At this time, the recorded sound range is repeatedly recorded from the lowest sound to the highest sound that humans can actually produce. That is, the voice file is recorded data of human voices uttered so as to match the pitches of the respective musical scales from the lowest range that can be uttered by humans to the highest range.

  In order to reproduce music using a musical scale according to the present invention, each compositional program corresponding to the composition of the music is selected by the performance control unit 100. For example, program 1 is selected for the C major key (C major), program 2 is selected for the C # key, program 3 is selected for the D key, and the like. If the music is in the minor key, the program is selected based on the corresponding major key as the corresponding major music. That is, if the key is lowered by 3 degrees from the major key, it becomes a minor key. For example, in the case of the A minor key (b minor), the key corresponding to the A minor key (b minor) is the C major key (c major). A program is selected.

  When the composition-specific program corresponding to the composition of the music is selected, the performance control unit 100 reproduces, for each sound of the music, an audio file corresponding to each sound of the scale corresponding to the selected composition-specific program. . For example, if “D-E-F” is written in order on the score for the music of the D key (D major), as shown in FIG. File-"So" audio files are played in order. At this time, the sound of each file has not only the pronunciation of each floor name but also the pitch of the corresponding scale. Further, according to the present invention, each audio file is continuously reproduced for a time corresponding to the length of each note on the score, that is, reproduced in time with the time signature.
