Pseudo-octave

Hey little one, have you heard of music notes? Well, musicians use different notes to make songs. And sometimes they want to make their songs sound higher or lower but not change the whole melody. So, they use something called pseudo-octave.

An octave is a group of eight notes that repeat themselves in a pattern. Imagine you're counting from one to eight, and after reaching eight, you start again from one. That's what an octave is like. In music, the difference between two notes that are an octave apart is that one sounds higher than the other.

Now, a pseudo-octave is a group of notes that come after each other like an octave. But, rather than the traditional eight notes, it only has four. So, musicians use it to make their songs sound higher or lower without changing the whole tune. Think of it as a half-octave or a mini-octave.

In summary, pseudo-octave is a group of four notes used by musicians to make a song sound higher or lower without changing the whole melody. It's like a mini-version of an octave, which is a group of eight repeating notes.
