Harmonizing the Major and Minor Scale

[Dude]

Hello.....
I have been working this harmonizing in 3rds on both the major and Minor scales.I completely understand this in relation to the different intervals, and have a good grasp of this in relation to the fretboard ie. (learning where these notes fall in relation to each other). So lets call this an acedemic understanding of this subject.
Would someone please give me examples of the importance of this on a "musicall" level. What will this allow me to do musically? Are these harmonys scattered through different solos and played as double stops? Do you use them as chord tones in solos?
I hope you understand what I'm getting at here,basically I understand the Why's and How's, I don't understand the When and what's....

Thanks for your help......

Yes on all accounts. But you left out the fact that these "double stops" can be the basis for the "main riff" of a song as well.

Check out the Music section (http://www.zentao.com/guitar/lesson6/music.html) of lesson 6. Both Feel Your Love and The Zoo use these harmonies as the basis for the main riff of the song. Lesson 10 (if I can find the time to write the thing) will include the intro to Def Lepard's Too Late which is another good example of this.

In addition, understanding how the major and minor scales can be harmonized in 3rds is 2/3 of the knowledge you need to understand how chord progressions are put together. The other 1/3 will also be covered in the next lesson.

I feel like an idiot ....I completely overlooked the music example in that lesson that pretty much explained my question.
O.K. bear with me hear ....another question
I took the riff from "breaking the law" and pulled the notes out of it to construct the scale (basically for practice). I came up with... A-B-C#-F-G for the main riff.
I added in the rest of the notes to form the complete scale,but can't because of the G note. It needs to be a G# to make the proper scale wich I figure to be an F# minor scale F#-G#-A-B-C#-D-E-F#.
And then to top it off the Key Signatue is saying it is in the key of C on the tab.
Where did I go wrong?

[StoneDragon]

C rather than C#... third fret of the A sting is C. That gives you A-B-C-F-G.

And don't feel like an idiot. I haven't pointed those songs out in any way that ties together that old lesson with Lesson 9 and (eventually) lesson 10. You'd really have to be digging in and reviewing older lessons to catch that.

Duhhh !!!!!!!
Damn I can't believe I missed that note, it being a C and not a C#. I must have looked at it all for 10 minutes and still it didn't connect. Must be brain overload....
shows the importance of how one wrong note can throw off everything... hehehe I was all the way into an F# minor http://www.zentao.com/ubb/smilies/biggrin.gif
Thanks for setting me straight....
