Ok, kiddo, let's talk about the upper leading tone. You know how we sometimes sing a song and at the end we say "ta-da" or "dun-dun-dun"? Well, in music, when we play a certain note, it can make us feel like we need to play another note right away to finish the song or the part we are playing.
That note that makes us feel like we need to play another one right away is called the leading tone. Now, the upper leading tone is a specific leading tone that is one step higher than the note we start with. For example, if we start with the note C, the upper leading tone would be the note B.
The upper leading tone is important because it helps create tension in the music that makes us want to keep listening or playing. It's like a little cliffhanger that makes us excited to hear what comes next. That's why musicians use it a lot in their music, especially in classical music.
So next time you listen to a song or play an instrument, listen for the upper leading tone. It might be the key to making the music even more interesting and exciting!
