Seventh chords are really important in making music better. They add more depth and feeling to songs. These chords are made by adding an extra note to a three-note chord, called a triad. This extra note can change how the music feels and sounds.

How Seventh Chords Are Made

A seventh chord has four notes: the root, third, fifth, and the seventh note. This is different from triads, which only have three notes. There are several kinds of seventh chords, and each one has its own unique sound:

1. Major Seventh Chord - Sounds sweet and dreamy.
2. Minor Seventh Chord - Has a sadder or thoughtful feel.
3. Dominant Seventh Chord - Creates tension and makes you want to hear more.
4. Half-Diminished Seventh Chord - Sounds mysterious and uncertain.
5. Fully Diminished Seventh Chord - Feels intense and dramatic.
