摘要： The invention relates to electronic musical instruments and more particularly to multi-voice electronic musical instruments employing chord transformation, i.e. instruments, which do not perform chords directly, but transform them to chords close in sound, but with different musical characteristics. The chord transforming method of the present invention includes receiving a close harmony input chord as a list of not less than 3 notes, generating open harmony resulting chord as a list of notes equal to or greater than the number of input notes, of the notes of the input chord included without changes and/or transposed to another octave, as well as outputting the resulting chord, comprises identifying the highest note of the input chord, which is then included in the resulting chord without changes and transposing every note of the subset of the notes to be transposed in such a way, that every transposed note is lower in pitch, than the highest note of the input chord. As a technical result, achieved in the process of working on the task, there have been developed a possibility for a performer of playing close harmony piano style chords and producing open harmony guitar like multi-voice (up to 6 voices) chords with melodic position (highest note of the chord) on its place. This lets a performer build open harmony multi-voice chord progressions with only one hand, controlling melodic and octave position of every output chord in a natural performing way, i.e. getting the resulting chord's highest note identical to that of the input chord.
