Okay, let's imagine a group of people singing together. Some of them can sing really high notes, like the sound you hear when a bird sings. We call those people the "treble voices."
You know how sometimes you sing a song and it's a little too high for your voice? Well, that's what the treble voices are good at. They can sing those high notes really easily.
Just like people have different colored eyes or hair, our voices can also be different. Some people have voices that can sing really high, some have voices that can sing really low, and others have voices that are in between.
Now, let's think about a choir. A choir is a group of people who sing together. When a choir performs, they want to have a nice balance of different voices. They want some people singing really high, some singing in the middle, and others singing really low. That way, it sounds beautiful and harmonious.
The treble voices in a choir are a particular group of singers who can reach those high notes easily. They usually include children or adults with higher-pitched voices. It's almost like they are the "specialists" in singing the high parts.
When the treble voices sing, they add a beautiful and airy quality to the music. They bring brightness and zest to a song, kind of like the way the sunbeam lights up a room. It's very nice to have them in the choir because they can sing the high parts that others might find difficult.
So, think of the treble voices as the singers who can effortlessly reach those high notes, adding a magical touch to the music. They are like the birds of the choir, filling the air with their enchanting melodies.
