Subsidiary chord

Imagine you are starting with a big jigsaw puzzle. Some pieces of the puzzle might be very different from the others, but when you put them together, it creates a beautiful picture. Similarly, in music, when we combine different chords, it creates a beautiful sound. One type of chord is called a subsidiary chord.

A subsidiary chord is like a puzzle piece that fits between two other chords to help connect them together. It's like a friend that helps you get along with others. For example, if we have two chords that don't sound very good together, we can add a subsidiary chord in between to make them sound better.

Think of it like a sandwich – the two main parts are the bread, but the subsidiary chord is like the filling that makes it taste better. It helps to link two chords together smoothly to make a song sound complete. Subsidiary chords can be major or minor and can be used in different parts of the music, depending on what sounds best to the listener.

Overall, a subsidiary chord is a type of chord that helps connect two other chords together to create a beautiful sound in music.
