【摘要】：自动伴奏技术基本建立在欧洲七声大小调式的基础上,而针对中国五声民族调式的自动伴奏研究还非常薄弱。为此,面向蒙古族歌曲旋律,提出一种新的自动伴奏算法。根据蒙古族歌曲旋律的特征构建伴奏和弦生成算法,利用该算法和预先构建的和声进行规则库为主旋律生成伴奏的和弦序列。设计伴奏音型匹配算法,从预先构建的伴奏音型知识库中选取合适的伴奏音型,对选取的伴奏音型进行模进,从而生成伴奏。实验结果表明,该算法对于基础薄弱人群的认可度较高,可以满足他们对音乐的伴奏需求。
[Abstract]:The technique of automatic accompaniment is based on the European seven-tone mode, but the research on the Chinese five-tone national tone is still very weak. For this reason, a new automatic accompaniment algorithm is proposed for the melody of Mongolian songs. According to the melody characteristics of Mongolian songs, an accompaniment chord generation algorithm is constructed, and the algorithm and the pre-constructed harmony rule base are used to generate the accompaniment chord sequence for the main melody. The matching algorithm of accompaniment tone type is designed. The appropriate accompaniment type is selected from the pre-constructed knowledge base of accompaniment type, and the selected accompaniment type is modelled to generate accompaniment. The experimental results show that the algorithm can meet the needs of music accompaniment.
