Intervals are super important in music. They help create melody and harmony. An interval is just the space between two notes, and it can change how a piece of music makes you feel.

For example:

• A major third interval, which is four half steps, sounds happy and bright. This can make cheerful melodies.
• A minor sixth interval, which is eight half steps, can make music feel sadder.

Here are some examples:

• Major Third: From C to E
• Minor Sixth: From C to A♭

When it comes to harmony, intervals also decide how chords are built. Some chords sound nice together (consonant), while others might sound a little weird (dissonant).

Knowing how intervals work is super important if you want to write great music!
