There are five basic chords in music: major, minor, dominant seventh, diminished, and augmented. These chords form the basis of any song or piece of music. In this article, we will discuss each chord in detail and give some examples of songs that use each type.

The major chord is one of the most commonly used chords in music. It consists of the notes 1-3-5 and has a happy, uplifting sound. Some well-known songs that use a major chord include "Happy" by Pharrell Williams and "All You Need is Love" by The Beatles.

The minor chord is also very common in music. It consists of the notes 1-flat 3-5 and has a sadder, more mellow sound than the major chord. Some well-known songs that use a minor chord include "Love Hurts" by Nazareth and "Hallelujah" by Jeff Buckley.

The dominant seventh chord is made up of the notes 1-3-5-7 and has a more bluesy sound than other chords. It's often used in soul and R&B music. Some well-known songs that use a dominant seventh chord include "Sexual Healing" by Marvin Gaye and "Papa Was a Rolling Stone" by The Temptations.

The diminished chord is made up of the notes 1-flat 3-5-sharp 7 and has a tense, dark sound. It's not as commonly used as other chords but can be found in some jazz and classical pieces. Some well-known songs that use a diminished chord include "Requiem" by Wolfgang Amadeus Mozart and "All of Me" by John Legend.

The augmented chord is made up of the notes 1-3-5-sharp 8 and has an intense, almost futuristic sound. It's not as commonly used as other chords either but can be found in some modern pop songs. Some well-known songs that use an augmented chord include "Radioactive" by Imagine Dragons and "This Is How We Do It" by Montell Jordan.
