The B dominant eleventh chord, commonly referred to as B11, is a six-note chord that extends the B dominant seventh by incorporating the ninth and eleventh intervals, creating a rich and layered harmonic structure. Its notes are B (root), D♯ (major third), F♯ (perfect fifth), A (minor seventh), C♯ (major ninth), and E (perfect eleventh), combining to produce a sound that is both complex and harmonically compelling. This chord is frequently used in jazz, funk, and fusion styles to add depth and tension to chord progressions, allowing for smooth voice leading and extended harmonic exploration. The interplay between the dominant seventh, added ninth, and eleventh intervals gives the B dominant eleventh chord a spacious, textured quality that enhances musical expression and provides a dynamic foundation for improvisation and melodic development.
