What is a chord that broken into essential notes?

A chord is a musical term used to describe a group of notes played simultaneously. When a chord is broken into essential notes, it means that the chord is simplified to include only the most important notes, which are usually the root, third, and fifth notes of the chord.

For example, a C major chord would be broken down into the notes C, E, and G. These are the most essential notes of the chord, and they provide the basic structure and sound of the chord. The other notes in the chord, such as the seventh note, can be added to create a fuller sound, but they are not essential to the chord's basic structure.

Breaking chords into essential notes is a useful technique for guitar players, pianists, and other musicians who want to understand the basic structure of chords and how they work. It can also be helpful for improvising and creating new chords.
