Septimal kleisma

Okay kiddo, let's talk about septimal kleisma! First, let's start with what a kleisma is. A kleisma is a musical interval. An interval is the distance between two notes. If you take a piano, you can see that there are different keys with different sounds. If you play two different keys at the same time, they make a sound. That sound is an interval.

Now, a septimal kleisma is a specific type of interval that happens to be really hard to hear! It happens when you play three different notes together. The distance between the first and second note is called a perfect fifth. The distance between the second and third note is called a major third.

But here's where things get tricky. In regular western music, those two intervals don't quite match up perfectly. It's like you're trying to put together a puzzle with pieces that don't quite fit.

That's where the septimal kleisma comes in. It's a tiny adjustment you can make that makes those two intervals fit together perfectly! It's like finding that one piece of the puzzle that makes everything click.

Now, why would anyone want to use a septimal kleisma? Well, it can create really interesting and unique sounds in music. It's like adding a special flavor to your cooking. Not everyone will like it, but some people will love it!

So there you have it, kiddo. Septimal kleismas are a special interval that helps make music sound even better and more unique!
