Description

本発明は、電子弦楽器に用いて好適な楽音発生指示装置及び楽音発生指示方法に関する。 The present invention relates to a musical sound generation instruction apparatus and a musical sound generation instruction method suitable for use in an electronic stringed instrument.

本発明は、このような事情に鑑みてなされたもので、多少誤った運指操作が為されても、その操作ミスを許容してミストーンの発音を防ぎ、楽しく演奏練習することが出来る楽音発生指示装置及び楽音発生指示方法を提供することを目的としている。 The present invention has been made in view of the above circumstances, and even if a slightly wrong fingering operation is performed, it is possible to generate a musical sound that allows the operation error to be prevented and to prevent misson pronunciation and to practice playing happily. It is an object to provide an instruction device and a musical sound generation instruction method .

上記目的を達成するため、本発明は、音高指定操作により指定された複数の音高をそれぞれ構成音とするコードが成立しているか否かを判別し、コードが成立していないと判別された場合に、前記複数の構成音の音高を変更してコード候補とし、前記コード候補とされたコードが、それ以前にコード候補とされたコードを含む複数のコードによるコード進行の形態に相応しい適正コードであるか否かを判別し、適正コードと判別された場合に、前記適正コードと判別されたコードで楽音の発音を指示することを特徴とする。 In order to achieve the above object, the present invention determines whether or not a chord having a plurality of pitches specified by a pitch specifying operation is established, and determines that a chord is not established. If the, the codes candidates by changing the pitch of said plurality of component sounds, the code candidate code is in the form of a chord progression of a plurality of codes including a code which was previously a code candidate It is determined whether or not the chord is a proper chord, and when it is discriminated as a proper chord, the tone generation of the musical tone is instructed by the chord discriminated as the proper chord .

Claims
