摘要：本文通过对离调和弦在歌曲即兴伴奏中的具体运用进行阐述，并抓住其在歌曲即兴伴奏中相应的使用方法进行展开。针对其在歌曲即兴伴奏中的具体运用，本人从以下几个方面进行论述：一、离调和弦在作品高潮处的运用。二、结合歌词在作品需要强调的地方的运用。三、其在作品大二度出现处的运用。四、在同音反复处的运用。写作目的主要是对自己本科四年和声理论学习和自己长期钢琴实践练习的一次总结，希望学以致用，也希望能够带给广大的钢琴即兴伴奏爱好者们一次借鉴的机会。

歌曲即兴伴奏是一种复杂的并由多种音乐要素所构成的艺术形态，它包括旋律、和声、织体音型、各种表情术语，所需具备的钢琴，还包括个人的器乐演奏基础、试奏能力、即兴创新才能和准确的领会了解作者的写作目的，以便掌握作品的意境和情感。当然，和声是歌曲即兴伴奏中的重中之重。歌曲是否悦耳，完善，取决于它的和声配置是否得当。和声配置到位，必然给人以心情舒畅、和谐之感，而且能够陶冶一个人的情操。但如果使用不当，那发出来的便是不堪入耳的噪音，而在伴奏中用一些特殊的和弦不但不会破坏歌曲的完整性，还会使听众耳目一新，并能够使歌者的感情得到更好的抒发，从而歌曲就得到了更好的演绎。在伴奏中离调和弦恰恰就扮演着这样的角色。它的出现给了演奏者和歌者更大动力去演绎，更好的前提去发挥。它广泛用于各种题材、体裁的作品中，为音乐的色彩变化作出了举足轻重的贡献。
