How to Write a Song Using Just One Chord

Writing a song can feel daunting, especially if you're new to music theory or composition. However, you don't need complex chord progressions to create something compelling. In fact, it's possible to write an engaging song using just one chord. This approach focuses on rhythm, melody, and lyrics to carry the piece, proving that simplicity can be powerful.

Why One Chord Works

Using a single chord forces you to think beyond harmony and explore other elements of songwriting. Without chord changes to create movement, you rely on the melody, rhythm, and lyrical content to maintain interest. This can be a great exercise for beginners to build confidence or for experienced writers to challenge their creativity. Many traditional and modern songs, especially in genres like blues, folk, and drone music, lean on minimal harmonic structures with great effect.

Start by choosing a chord that feels right for the mood of your song. A major chord, like C or G, often sounds bright and uplifting, while a minor chord, like Am or Em, can evoke a more melancholic or introspective tone. Once you've picked your chord, you're ready to build the rest of the song around it.

Building Your Song

Begin with a simple strumming or picking pattern on your instrument—guitar, piano, or whatever you play. Experiment with different rhythms to create a sense of groove or pulse. For example, if you're using a G major chord, try strumming it in a steady 4/4 time, then vary the pattern by emphasizing certain beats or adding pauses. This rhythmic foundation will act as the backbone of your song, giving it structure without harmonic shifts.

Next, focus on the melody. Since the chord isn't changing, your vocal or instrumental melody needs to stand out. Play around with different notes within the scale of your chosen chord. If you're using C major, for instance, stick to the notes of the C major scale (C, D, E, F, G, A, B) to ensure your melody fits. Keep it simple at first, then add small variations to create interest over time.

Lyrics are another key element. With only one chord, your words need to tell a story or convey emotion effectively. Focus on a clear theme or narrative, and use repetition or subtle changes in phrasing to mirror the static harmony. Think of songs like "Tomorrow Never Knows" by The Beatles, which uses a single chord drone to create a hypnotic effect, paired with evocative lyrics.

Adding Depth Without Harmony

To prevent your song from feeling repetitive, experiment with dynamics and texture. Try playing your chord louder or softer in different sections to create contrast. If you have access to other instruments or production tools, add layers like percussion, bass, or ambient sounds to fill out the arrangement. Even a simple vocal harmony or a change in singing style can make a big difference.

You can also play with the structure of the song. Instead of a typical verse-chorus format, consider a more linear or cyclical approach, where the song evolves gradually through lyrical or rhythmic shifts. This can keep listeners engaged without relying on chord changes.

Final Thoughts

Writing a song with just one chord is a valuable exercise in creativity and restraint. It teaches you to focus on the essentials of music—melody, rhythm, and emotion—while proving that complexity isn't always necessary. Pick a chord, experiment with different ideas, and let the simplicity guide you. You might be surprised by how much you can express with so little.
