What is a chord progression?

A **chord progression** is a series of chords played in a specific sequence within a piece of music. These progressions form the harmonic foundation of a song, helping to establish its mood, style, and emotional tone. Each chord in the progression is typically related to the key of the music, creating a sense of movement and resolution as the progression unfolds. In Western music, chord progressions often follow common patterns that listeners find pleasing or familiar, such as the famous I-IV-V progression (using the first, fourth, and fifth chords of a scale). For example, in the key of C major, this would be the chords C major, F major, and G major. Composers and songwriters use chord progressions to guide the melody, build tension, and provide a framework for improvisation or vocal lines. Overall, understanding chord progressions is fundamental for musicians because they help convey emotions, create musical interest, and support the structure of a song.

A **chord progression** is a sequence of chords played in a specific order within a piece of music. Chords are groups of notes played together, and when arranged in a progression, they create the harmonic foundation and emotional flow of a song. Chord progressions help establish the key, mood, and structure of music, guiding how melodies and rhythms interact. In most Western music, chord progressions follow patterns based on scales and harmony rules. For example, a common progression in pop music is the I–V–vi–IV progression, which uses the first (I), fifth (V), sixth minor (vi), and fourth (IV) chords of a key. This pattern creates a familiar and pleasing sound that listeners often recognize. Overall, chord progressions are fundamental to songwriting and composition, shaping how music moves and expressing different feelings, from tension and resolution to happiness and sadness. Musicians use them creatively to support melodies and create dynamic musical experiences.
