Neutral interval

Alright, so let's talk about neutral intervals. Imagine you have a line with some marks on it. Each mark represents a different sound or note. When you play two notes that are close to each other on the line, it creates an interval.

Now, some intervals sound happy or sad, but some intervals don't really sound like either. These are called neutral intervals. It's like when you see a plain white shirt - it's not colorful, but it's not black or gray either. So neutral intervals are kind of in the middle, not sad or happy.

Let's take an example. If you play the note C and then the note D, it creates a happy sounding interval called a major second. But if you play the note C and then the note C#, it creates a sad sounding interval called a minor second.

But if you play the note C and then the note C natural, which means it's neither higher nor lower, it creates a neutral interval called a unison. It's like when you have two of the exact same things next to each other and they match perfectly.

Another example is the note C and the note G#. This creates a sad sounding interval called an augmented fifth. But if you play the note C and the note G natural, it creates a neutral interval called a perfect fifth. It's like when you have two things that are similar, but not exactly the same.

So neutral intervals kind of give you a break from happy or sad sounds and are just kind of in the middle. It's like listening to something that doesn't have a strong feeling attached to it but still sounds nice.
