What is the structure of a Dominant 7th chord in?

A Dominant 7th chord is built on the root of the chord and consists of four notes: the root, major third, perfect fifth, and minor seventh. The structure of this chord typically includes these notes stacked in thirds, which sets the foundation for the chord to be in root position.

In root position, the root note is the lowest pitch. For example, in the case of a G7 chord (the G Dominant 7th chord), the notes are G (root), B (major third), D (perfect fifth), and F (minor seventh). When arranged in this order, you have the G note as the bass note, making it a distinct and stable sound typical of a dominant chord and allowing it to function correctly in harmonic progressions.

The other inversions would place different notes of the chord in the bass position, altering how the chord is perceived and functionally used in music. Understanding the root position is essential for grasping the foundational characteristics of a Dominant 7th chord, particularly in Western music harmony, where the tension and resolution qualities of this chord play a critical role in establishing musical direction.
