What is the difference between a Minor chord and a Major chord?

So let me start off by explaining what a chord is to provide some context. A chord is three notes put together, and each of the notes has a very specific function and interval in the chord. So, typically, when we have things like C major and C minor, it refers to a change in the third degree of the chord. In a chord, we have the first note, the third note, and the fifth note: 1, 3, 5. And so, typically, the difference between major and minor lies with the third one. And if it's a minor, the distance between the first note and the third note will be what is known as a minor third, whereas if it's a major, the note between the first note and the third note will be known as a major third. So, typically, the difference between a minor third and a major third is one-half step.
