What are semitones?

Semitones are the tiny steps that make music sound smooth and interesting.

Imagine you're climbing a staircase, each step is like a note in a song. Now picture a staircase with double the number of steps, those extra steps between each one are semitones. They’re like the little jumps that help your favorite songs go from happy to silly or calm to exciting.

Think about a piano. When you press a key, it plays a note. If you press the very next key, it’s a semitone higher, just like one step up on the staircase. That small jump makes your music flow and change mood, whether you're playing a bouncy tune or a soft lullaby.

If you’ve ever heard two notes that sound really close together, almost like they’re whispering to each other, those are semitones at work. They give music its character, just like how a small change in your voice can turn a laugh into a sigh.
