Description

上記目的を達成するため、本発明の楽音発生装置は、音高指定操作により指定された少なくとも３つの初期音高に基づいて初回和音を判定する初回和音判定手段と、前記初回和音判定手段により判定された初回和音からスケールを判定するスケール判定手段と、前記少なくとも３つの初期音高を指定する音高指定操作に続く音高指定操作により順次指定される複数の音高と、前記スケール判定手段により判定されたスケールとに基づいて、当該スケール上の和音を順次導出して発音する和音発音手段とを具備することを特徴とする。 In order to achieve the above object, the musical tone generating apparatus of the present invention is determined by the initial chord determining means for determining the initial chord based on at least three initial pitches specified by the pitch specifying operation, and the initial chord determining means. A scale determining means for determining a scale from the first chord, a plurality of pitches sequentially specified by a pitch specifying operation following the pitch specifying operation for specifying the at least three initial pitches, and the scale determining means Based on the determined scale, chord sound generation means for sequentially deriving and generating chords on the scale is provided.

本発明の電子楽器は、前記音高指定操作を行う演奏入力操作子と、本発明による楽音発生装置と、前記楽音発生装置の和音発音手段によって導出された音に基づき楽音を生成して出力する楽音出力部とを備えることを特徴とする。 Electronic musical instrument of the present invention, a performance input operator performing the pitch designation operation, a musical tone generating apparatus according to the present invention, to generate a musical tone based on the sound that is derived by a sum sound onset sound unit of the musical tone generating apparatus And a musical tone output unit for outputting.

本発明の楽音発生方法は、楽音発生装置が、音高指定操作により指定された少なくとも３つの初期音高に基づいて初回和音を判定し、前記判定された初回和音からスケールを判定し、前記少なくとも３つの初期音高を指定する音高指定操作に続く音高指定操作により順次指定される複数の音高と、前記判定されたスケールとに基づいて、当該スケール上の和音を順次導出して発音することを特徴とする。 Tone generating method of the present invention, the tone generator may determine the first chord based on at least three initial pitch designated by the pitch designation operation, determines the scale from the determined first chord, at least Based on a plurality of pitches sequentially specified by a pitch specifying operation following the pitch specifying operation for specifying three initial pitches and the determined scale, a chord on the scale is sequentially derived and pronounced. It is characterized by doing.

本発明のプログラムは、コンピュータに、音高指定操作により指定された少なくとも３つの初期音高に基づいて初回和音を判定するステップ、前記判定された初回和音からスケールを判定するステップと、前記少なくとも３つの初期音高を指定する音高指定操作に続く音高指定操作により順次指定される複数の音高と、前記判定されたスケールとに基づいて、当該スケール上の和音を順次導出して発音するステップと、を実行させることを特徴とする。 The program of the present invention includes a step of determining an initial chord based on at least three initial pitches specified by a pitch specifying operation on a computer , a step of determining a scale from the determined initial chord, and the at least 3 Based on a plurality of pitches sequentially designated by a pitch designation operation that designates two initial pitches and the determined scale, a chord on the scale is sequentially derived and pronounced And executing the step.
