Okay kiddo, have you ever heard of a neapolitan ice cream? It's when you have three different flavors in one big container. Well, the neapolitan scale is like that, but instead of ice cream flavors, we have different notes that we play on a piano or other musical instrument.
This scale comes from a part of Italy called Naples (that's why it's called neapolitan), and it's a special scale that isn't used very often in music. It's made up of seven different notes, just like the regular major scale you might have learned already. But, instead of starting on the first note like we normally would, we start on the second note.
So, if we were playing the neapolitan scale in the key of C, we would start on D instead of C. Then we play the next six notes, which would be E, F, G, A, Bb, and then back to C.
It sounds a little different than the regular major scale, and it might make you feel a certain way when you hear it. Some people say it sounds a little bit sad or mysterious.
So, that's the neapolitan scale in a nutshell! It's like a neapolitan ice cream of musical notes, and it sounds a little different than what we're used to hearing.
