Description

本発明は、楽曲を鍵盤楽器で演奏する際の難易度を評価する装置に関し、特に両手を使った鍵盤演奏の難易度を評価する演奏難易度評価装置、プログラム及び電子楽器に関する。 The present invention relates to an apparatus for evaluating the difficulty level when playing a musical piece with a keyboard instrument, and more particularly to a performance difficulty evaluation apparatus , a program, and an electronic musical instrument for evaluating the difficulty level of a keyboard performance using both hands.

本発明は、このような事情に鑑みてなされたもので、両手を使った鍵盤演奏の難易度を評価することができる演奏難易度評価装置、プログラム及び電子楽器を提供することを目的としている。 The present invention has been made in view of such circumstances, and an object of the present invention is to provide a performance difficulty evaluation device , a program, and an electronic musical instrument that can evaluate the difficulty of keyboard performance using both hands.

上記目的を達成するため、本発明の演奏難易度評価装置は、曲を構成する音符夫々を演奏するに用いられる指を表す指番号および当該音符の演奏パートを識別するパートデータを含む音符データの中から、当該音符データに含まれるパートデータに基づいて予め設定された関係にある第１乃至第４の音符データを検索し、該当する第１乃至第４の音符データにそれぞれ含まれる指番号に基づき両手で演奏する場合の難易度のタイプを判定するタイプ判定手段と、前記タイプ判定手段により判定されたタイプ毎の難易度値を曲を両手で演奏する場合の難易度として取得する難易度取得手段とを具備することを特徴とする。 In order to achieve the above object, the performance difficulty evaluation device of the present invention is a musical note data including a finger number representing a finger used to play each musical note constituting a song and part data for identifying a performance part of the musical note. The first to fourth note data having a preset relationship based on the part data included in the note data is searched from among the finger numbers included in the corresponding first to fourth note data. Based on the type determination means for determining the type of difficulty level when playing with both hands based on the difficulty level acquisition for acquiring the difficulty level value for each type determined by the type determination means as the difficulty level when playing a song with both hands Means.

Claims

Among the note data including the finger number used to play each note constituting the song and the part data for identifying the performance part of the note, the note data is preset based on the part data included in the note data. Type determination means for searching for first to fourth note data having the same relationship and determining the type of difficulty when playing with both hands based on the finger numbers respectively included in the corresponding first to fourth note data When,
A difficulty level evaluation device comprising: difficulty level acquisition means for acquiring a difficulty level value for each type determined by the type determination means as a difficulty level when a song is played with both hands.

The type determination means sequentially searches the first to fourth note data having a predetermined relationship based on the part data included in the note data, and specifies the finger data included in the corresponding first to fourth note data. Determine the type of difficulty when playing with both hands based on the number,
2. The difficulty level acquiring unit according to claim 1, wherein the difficulty level acquisition unit sequentially accumulates the difficulty level value determined for each type determined by the type determination unit, and acquires the level of difficulty when playing a song with both hands. Performance difficulty evaluation device.

The type determination means includes the first sound me to be evaluated, the second sound other of the opposite part at the same sound generation timing as the first sound me, the third sound next and the first sound next to the sound generation timing after the first sound me. Search means for sequentially searching each note data of the fourth sound diagonal which is the sound generation timing next to the second sound other of the opposite part at the same sound generation timing as the sound me as the first to fourth note data. The performance difficulty evaluation device according to claim 1, wherein:

The type determining means includes
Each time the first note data to be evaluated is updated with the right hand part as the subject, the first to fourth note data used for type determination of the difficulty level are sequentially searched, and the corresponding first to fourth note data are retrieved. First determination means for determining the type of difficulty to play with both hands based on the finger numbers included in each data;
Each time the first note data to be evaluated is updated with the left hand part as the subject, the first to fourth note data used for the type determination of the difficulty level are sequentially searched, and the corresponding first to fourth note data are retrieved. The performance difficulty evaluation device according to claim 1, further comprising: a second determination unit that determines a type of difficulty level to play with both hands based on finger numbers included in each data.

The first and second determination means are determined by the degree of separation of a finger played with one hand and the degree of separation of a finger played with the other hand, based on finger numbers included in the first to fourth note data, respectively. 5. The performance difficulty evaluation device according to claim 4, wherein the type of difficulty of playing with both hands is determined in accordance with the left / right symmetry of finger usage of both hands.
