Extended harmony

Okay, so when we talk about a song or piece of music, it's usually made up of different melodies and chords. Chords are like groups of notes played together that make a specific sound.

Now, sometimes in music, we want to make the chords sound more interesting or complex. This is where extended harmony comes in. We can add extra notes to the chords to make them sound fancier and cooler!

For example, if we have a chord that's called "C major," it's made up of three notes: C, E, and G. But with extended harmony, we can add extra notes like Bb or D to make it a C7 or C9 chord. These extra notes add more flavor and richness to the sound of the chord.

Think of it like adding different toppings to your pizza! You can start with just cheese (C major chord), but if you add some pepperoni (an extra note), it makes it tastier and more interesting (a C7 chord).

So, extended harmony is just a way to make the chords in music sound fancier by adding extra notes to them. It's like putting a fancy hat on your chord to make it stand out!
