Abstract

Melody harmonization, which involves generating a chord progression that complements a user-provided melody, continues to pose a significant challenge. A chord progression must not only be in harmony with the melody, but also interdependent on its rhythmic pattern. While previous neural network-based systems have been successful in producing chord progressions for given melodies, they have not adequately addressed controllable melody harmonization, nor have they focused on generating harmonic rhythms with flexibility in the rates or patterns of chord changes. This paper presents AutoHarmonizer, a novel system for harmonic density-controllable melody harmonization with such a flexible harmonic rhythm. AutoHarmonizer is equipped with an extensive vocabulary of 1462 chord types and can generate chord progressions that vary in harmonic density for a given melody. Experimental results indicate that the AutoHarmonizer-generated chord progressions exhibit a diverse range of harmonic rhythms and that the system’s controllable harmonic density is effective.

根据旋律生成和弦进行，和声节奏灵活，和声密度可控

旋律和声是指生成一个和弦进行，以补充用户提供的旋律，这仍然是一个重大挑战。和弦进行不仅必须与旋律和谐，还必须与旋律的节奏型相互依存。虽然以前基于神经网络的系统能成功地为给定旋律生成和弦进行，但它们并没有充分解决可控旋律和声的问题，也没有专注于生成和弦变化率或模式灵活的和声节奏。本文介绍的 AutoHarmonizer 是一种新颖的系统，用于和声密度可控的旋律和声，并具有这种灵活的和声节奏。AutoHarmonizer 配备了由 1462 种和弦类型组成的丰富词汇，可以为给定的旋律生成和声密度不同的和弦行进。实验结果表明，AutoHarmonizer 生成的和弦行进表现出多种多样的和声节奏，而且系统的可控和声密度非常有效。
