变和弦在钢琴即兴伴奏中的运用

Use of Altered Chord in the Improvisational Piano Accompaniment

变和弦是一种具有特殊音响效果和表现意义的和弦,在钢琴即兴伴奏中,离调变和弦向其临时的主和弦根音作四度或二度上行解决可获得离调效果;运用调内变和弦时必须将所包含的半音解决到调内的稳定音级;歌曲旋律中大、小调的因素相互渗透或是大小调之间相互转调时运用变和弦可实现调式交替;使用变和弦能够起到丰富和声色彩、增加和声表现力的独到作用。

With its special sound effect and manifestation, altered chord is used in improvisational piano accompaniment to enrich the harmony and expressive force. From the practical aspect, this paper tries to summarize the choice and use of altered chord in improvisational piano accompaniment, based on analyses of several songs.
