A chord chart is a visual representation of the chords used in a song, typically displayed in a simple format. It shows the chord names above the lyrics or melody, allowing musicians to quickly understand which chords to play at specific points in the song. Chord charts are commonly used by guitarists, pianists, and other instrumentalists to accompany singers or other musicians. These charts can vary in complexity, from basic versions that only include chord names to more detailed charts that indicate strumming patterns or finger placements. Chord charts are often used in genres like folk, rock, and pop music, making them a valuable tool for both beginners and experienced musicians.
