Jazz harmonyとは 意味・読み方・使い方

Jazz harmony is the theory and practice of how chords are used in jazz music. Jazz bears certain similarities to other practices in the tradition of Western harmony, such as many chord progressions, and the incorporation of the major and minor scales as a basis for chordal construction, but departs in significant ways. In jazz, chords are often arranged vertically in major or minor thirds, although 'stacked' fourths are also quite common. Also, jazz music tends to favor certain harmonic progressions and includes the addition of "tensions", intervals such as 9ths, 11ths, and 13ths to chords. Additionally, scales unique to style are used as the basis of many harmonic elements found in jazz. Jazz harmony is notable for the use of seventh chords as the basic harmonic unit more often than triads, as in classical music.
