Just doing an internet search for “musical scales,” “major scale,” “minor scale” or “chromatic scale” will produce many results that will get you started. Although Tony occasionally gives some explanation about one or more scale types in the daily lessons, it will take a long time to answer your question via TAC daily lesson references, especially since we no longer have access to the “Libraries” of daily lessons. You’re going to need to look outside of TAC to get much information if your needs are current, and I think they are.
If you do a little internet research, you’re likely to find some discussion of “modes” of the major scale. Don’t worry if you don’t understand all of that at once. Let it sink in over time. You will see in time that the natural minor scale (there are actually several scales that have a “minor” or “sad” sound) is noting more than the sixth mode of the major scale. The major scale is defined by the intervals or distances between adjacent notes. I will not fall into the trap of writing a book here again as I did in many posts on the old forum. I will leave it to you to find what you need because it is very easy to find.
