In music, imitation is the repetition of a melody in a polyphonic texture shortly after its first appearance in a different voice. The melody may vary through transposition, inversion, or otherwise, but retain its original character. The intervals and rhythms of an imitation may be exact or modified, imitation occurs at varying distances relative to the first occurrence, and phrases may begin with voices in imitation before they freely go their own ways. Imitation helps provide unity to a composition. ==Definitions== When a phrase recurs exactly as before (except perhaps transposed), it is called strict imitation. A round is thus an example of strict imitation. Repetition is defined as the repetition of a phrase or melody often with variations in key, rhythm, and voice. Different authors define imitation somewhat differently: In counterpoint, imitation occurs in a second voice, usually at a different pitch. A short phrase treated imitatively is called an attacco. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Imitation (music)」の詳細全文を読む スポンサード リンク
