Nonchord tone

When we listen to music, there are some notes that are not part of the main chords, but they still sound good when played right after or before the chords. These notes are called nonchord tones.

Imagine you have a toy box with different shapes like squares, circles, and triangles. When you take out a square and a triangle and put them next to each other, they don't match, but when you add a little circle in between them, it makes the whole thing sound better.

Nonchord tones are like the little circle that makes the toy box look better. They add variety and color to the music, making it sound more interesting and enjoyable.
