Chord Functions
Chord functions refer to the roles that different chords play within a musical context, particularly in harmony. In Western music, chords are typically categorized into three main functions: tonic, dominant, and subdominant. The tonic chord serves as the home base or point of rest, while the dominant chord creates tension that seeks resolution back to the tonic. The subdominant chord acts as a bridge between the tonic and dominant, helping to establish movement within a progression.
Understanding chord functions is essential for analyzing and composing music. By recognizing how these chords interact, musicians can create effective progressions that evoke specific emotions or drive a piece forward. This knowledge is foundational for genres ranging from classical to jazz and pop, allowing for richer musical expression and structure.
