bluedominant

Bluedominant is a term used in some jazz and blues theory discussions to describe a dominant seventh harmony that carries a pronounced blues coloration. The label is not standardized across theory texts, and its exact meaning can vary by teacher or school. In general, bluedominant refers to a V7 chord whose melodic and coloristic content emphasizes blues scale tones and altered tensions rather than purely classical voice-leading.

Construction and color: A bluedominant chord is typically the dominant seventh built on the fifth scale degree of the key (V7). The “blue” aspect comes from incorporating blues-scale color tones and common alterations such as flat ninth, sharp ninth, flat fifth, or sharp fifth. Voicings and lines often feature blues-scale pitches or chromatic approach notes that emphasize the expressive, bluesy feel while still functioning harmonically as the dominant of the tonic. Improvisers may outline the blues scale over the V7 or use altered tensions to create a distinctive, expressive pull toward the tonic.

Role in harmony: The bluedominant often appears in blues, jazz, and fusion contexts where color is prioritized alongside functional cadence. It is frequently used in I–IV–V blues progressions, as well as in ii–V–I progressions with a blues-inflected dominant. The approach can involve tritone substitution, chromatic movement, and melodic emphasis on blue-note tensions to heighten the sense of movement toward the rest of the harmony.

Terminology and usage: Because the term lacks a single, formal definition, it is best understood as a descriptive label for dominant chords colored by blues-toned tensions and colorings. It reflects a practical approach to harmony and improvisation rather than a rigid theoretical category.
