A sequence of chords that creates the harmonic framework of a song. The most common progression in popular music is I-V-vi-IV (in C major: C-G-Am-F).
Roman numerals (I, IV, V) are used to describe progressions because they work in any key — I-V-vi-IV in C major is the same structural pattern as I-V-vi-IV in G major.
Understanding chord progression is essential for reading and writing music accurately. Whether you are a beginner learning to read notation or an experienced composer, knowing how this musical element works improves your musicianship.
