ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an apparatus and a method for editing a music score, and more particularly to such an apparatus and a method processing a music score data set including information to display a music score in musical notation, a performance data set including information to perform a piece of music as defined by the music score, and an intermediate data set including information to mediate between the music score data set and the performance data set and to reflect edition of the music score data set into the performance data set, so that the performance data set is efficiently composed reflecting the edition on to the music score data set.
2. Description of the Prior Art
There has conventionally been known in the art an apparatus of a data processing type which displays a music score on the display screen based on music score data and prints the music score on paper in the style exhibited on the screen. In such an apparatus, icons of various kinds of notes and of various kinds of musical signs (or symbols) are to be arbitrarily inputted using an input device such as a keyboard utilizing the data processing technology.
There has also been known in the art an apparatus of a data processing type which converts the music score data for screen display into performance data for driving a tone generating module such as a MIDI apparatus to perform music. A music score contains icons or symbols of various notes and various other signs located at respective determined positions on the five-line staves, and the music score data for exhibiting a visual image of a music score on the display screen contains display position data, note type data and sign type data to place the note symbol images and various sign symbol images at the respective proper positions on the screen. The apparatus, therefore, builds performance data from the music score data by utilizing such various data elements in the music score data.
The music score data, however, are data for the purpose of displaying musical notations on a screen plane and, therefore, do not contain data concerning the progression of time. For this reason, the production of performance data from music score data inevitably requires the formation of a whole performance data covering from the top through to the tail of the score data. In case a portion or portions of the score data is or are edited, the conversion from the score data into the performance data will necessitates complete amendment of the performance data from its beginning to end corresponding to the whole length of the partly edited score data, and not a partial amendment of the edited performance data. This makes the performance data producing work after the score edition inefficient, and requires much time after the edition of the music score data.
SUMMARY OF THE INVENTION
It is, therefore, a primary object of the present invention to solve the above-mentioned drawbacks involved in such a conventional apparatus or method of editing music score data and producing performance data by introducing intermediate data which will permit a partial adjustment of the performance data according to a partial edition to the music score data where the performance data is produced based on the music score data, thus eliminating an annoying multiplicative amount of work for complete production again from the beginning to the end of the performance data.
In order to accomplish the object of the present invention, the invention provides a music score editing apparatus comprising: a music score data composing module which composes a music score data set including display event data that define notes and signs in musical notation and respective positions of the notes and signs for displaying a music score in a form of musical notation; an intermediate data creating module which creates an intermediate data set corresponding to the music score data set, the intermediate data set including a note data set which contains note event data corresponding to the notes and their respective positions, and a sign data set which contains sign event data corresponding to the signs and their respective positions; and a performance data creating module which creates a performance data set corresponding to the intermediate data set, the performance data set including performance event data that define notes to be played in terms of at least pitches and generation times of the respective notes to perform a musical piece as defined by the music score data set.
The note event data may contain identifying information for identifying each note event among the plural note events, and note event data for each note may include at least note generation time information, note pitch information and note duration information. The sign event data may contain program indicating information for indicating the processing program for the respective signs and parameter information to be used under the processing program, and may be stored in a predetermined priority order.
According to the present invention, an intermediate data set containing note event data for each of the note events and sign event data for each of the sign events is created based on the music score data set, and then a performance data set containing performance event data for each of the performance events based on the note event data and the sign event data in the intermediate data set. Therefore, when notes or signs are edited in the music score data set, the associated note event data and sign event data are edited in the intermediate data set, and the performance data set is edited at portions therein which are respectively associated with the edited portions of the intermediate data set to finally obtain an edited performance data set. Thus, the burden in the edition processing of a performance data set caused by edition on to a music score data set will be alleviated, thereby realizing efficient edition processing in a short time when processed using a personal computer or like apparatuses.
As will be understood from the above description about the apparatus for editing a music score data set, a sequence of steps each performing the operational function of each of the structural element modules of the above music score editing apparatus will constitute an inventive method for editing a music score data set according to the spirit of the present invention.
Further as will be understood from the above description about the apparatus and the method for editing a music score data set, a storage medium containing a program executable by a computer system, which program comprising program modules for executing a sequence of the processes each performing the operational function of each of the structural element modules of the above music score editing apparatus or performing each of the steps constituting the above music score editing method will reside within the spirit of the present invention.
Further as will be apparent from the description herein later, some of the structural element modules of the present invention are configured by a computer system performing the assigned functions according to the associated programs. They may of course be hardware structured discrete devices performing the same functions.
The present invention may take form in various components and arrangement of components including hardware and software, and in various steps and arrangement of steps. The drawings are only for purposes of illustrating a preferred embodiment and processes, and are not to be construed as limiting the invention.
