Okay, so imagine you're playing a game with a ball. There are different players in the game, and each player has a special position they play. One of the most important players in the game is called the "dominant" player. This player is like the leader and can control what happens in the game.
Now, sometimes in the game, the dominant player wants to have even more power and control. So they call for help from some of their friends who are also really good at the game. These friends are called the "extended dominant" players.
When the extended dominant players come onto the field, they work together with the dominant player to make even stronger and more powerful moves. They support and reinforce the decisions and actions of the dominant player.
Think of the dominant player as the captain of a team, and the extended dominant players are like the assistant captains. They all work together to make the team perform at its best.
In music, the concept of an "extended dominant" is similar. It refers to a chord or a group of chords that help to strengthen and lead to the main chord or key of a song. Just like the dominant player and their friends in the game, the extended dominant chords provide extra power and control to the main chord or key in the music.
So, the extended dominant is like a special group of chords that make the main chord or key of a song sound even better and more exciting. It's like adding more players to the game to make it more fun and interesting.
