How do you change a major triad to a minor triad?

Answer:
In order to change a major (M) triad to a Minor (m) triad, simply lower the middle note a half step.

For example, if you have the CM triad, you have
Root (the bottom note): C
3rd (the middle note): E
5th (the top note): G

In order to make CM into cm (remember: Major is always capital, Minor is always lower case), lower the 3rd (E) a half step, or flat it. So E becomes E flat, and it turns to:
Root: C
3rd: E flat
5th: G

And you have Minor!

Another example is the G Major (GM).
Root: G
3rd: B
5th: D

to make GM to gm, flat the 3rd.

Root: G
3rd: B flat OR A sharp
5th: D

And you have gm. It's really simple.
