Antimajor

Antimajor is a term used in music theory to describe a chord that is functionally similar to a major chord but with a specific alteration. This alteration typically involves lowering the third degree of the chord by a semitone, while the root and fifth remain the same. For example, a C major chord consists of the notes C, E, and G. An antimajor chord based on C would consist of C, E-flat, and G, which is the same as a C minor chord. However, the term "antimajor" is often used in contexts where the chord's role or perceived quality is distinct from a standard minor chord.

The concept of antimajor chords is not universally recognized or defined in traditional music theory textbooks. It is more commonly found in discussions related to certain genres or analytical frameworks that explore nuanced harmonic relationships. The term might arise when a composer or theorist wishes to highlight a specific harmonic function that deviates from typical major or minor progressions. For instance, an antimajor chord could be used to create a sense of unresolved tension or a unique color that is neither purely major nor fully minor. Its application is often subjective and dependent on the specific musical context.
