TWO AND A HALF / THREE AND A HALF

We are forging onward to Music Theory Lesson #2!

So last entry, we discussed the 12 notes of the Western Harmony System, and gave every single one of them a name. Now, we're going to start organizing them in ways that are musically useful.

How many of you remember this woman?



Remember "Do Re Mi Fa So La Ti Do"?

Yes. Tonight, we're going to talk about the mother of all scales: THE MAJOR SCALE.

There are several scales at our disposal, and believe me, we're going to eventually cover all of them, but we have to start here, because this is the one scale from which all other scales are derived.

When I said it was the "mother of all scales," I wasn't kidding.

Then again, maybe you could make a case for the Chromatic Scale being the mother, but I don't. Just assume that the Chromatic Scale gave all of the others up for adoption, and since the Major Scale is the one who stepped in and did the job, she is the one we're honoring today.

(What the hell am I talking about.)

Ahem. Moving on...

Here is a C Chromatic Scale:



Now... we come up with a Major Scale using an important formula known as TWO AND A HALF / THREE AND A HALF. Remember the WHOLE STEP and the HALF STEP from last time? We're going to organize them in this order:

WWH / WWWH

Two and a half on the left. Three and a half on the right.

Start with "C" and move a whole step (2 notes) to the right. We end up with a "D", right? Next, move another whole step to the right. The result is "E." That's two whole steps! Now we need to finish the "Two and a half" part of the equation with a half step. From "E", this ends up being an "F."



C - D - E - F.

Follow me so far?

We still have "WWWH" to deal with.

Starting with "F", we move a whole step to "G", a whole step to "A", a whole step to "B", and finally a half step to "C." THREE AND A HALF.



This gives us all 8 notes of a C MAJOR SCALE.



Let's isolate them from the rest for a few minutes:



It's probably all-too-apparent at this point why I chose the key of "C" for this exercise; no sharps or flats to deal with on this one.

Now that you know the notes that make up a C Major Scale, here is where to find them on the neck.



First, let's look at the scale as if we were playing it on one single string. Notice the way that the WWH / WWWH relationship plays out on the fretboard of a guitar. We find our "C" starting on the 3rd fret of the "A" string.

"D" is on the 5th.

"E" on the 7th.

"F" on the 8th.

"G" on the 10th.

"A" is on the 12th fret, or the "snake eyes" as we like to call that area of the guitar neck.

"B" is on the 14th, and then "C" falls on fret #15, which corresponds to fret #3.



But nobody plays a scale all on one string, because that'd be a hassle. So here are two other ways that you can play the C Major Scale instead. The one on the left is commonly known as the "condensed" version, because all of the notes are compacted into a small area. The one on the right is called the "extended" version because you're going to have to stretch those fingers just a little more to play it. This doesn't mean it's any less useful.

CONDENSED: EXTENDED:


Practice playing those two versions of the scale; memorize the shapes!

What we've done tonight is we've established an extremely critical framework for understanding all other scales. And that's not all. The implications of this are even more far-reaching than what it might seem at the moment.

So congratulate yourself on a job well done, and when we return next time, we'll begin talking about the "atomic particle" of music: the INTERVAL.

I read this post because it had pretty pictures.

Again, good work. Keep 'em coming. Another link on my firefox favorites tab...I'll be checking it daily.

No way. You actually did the Julie Andrews thing. I almost made a joke to you about putting a link with her singing "DoReMi" on your next blog. I didn't think you'd actually do it. My mom would be so proud of you. --Christi

right above the picture of the C Major Scale, you called it a C Chromatic Scale. we all know what you mean, but i thought you might want to correct that just to keep things clear. i'm looking forward to the next lesson. *smile*

Thom said...

Not sure what you mean, Angel. That really is a C Chromatic Scale. The Major Scale doesn't appear till later on down.

Angel said...

you're right. duh. i overlooked the notes in parenthesis which make the scale Chromatic. sorry, my bad. *sheepish grin* downloaded "the miracle" today. love it. mighty nice licks on that ax of yours. can't wait for the rest of the album. =)

Well...I didn't really understand most of this. I've never really been good with any of the sciences, least of all music theory. However, I think I will keep reading your blogs, just in case I come across something that does make sense to me :).

p.s. I got your new song through the e-mail list, and it is quite good! A little more poppy than I expected, but still good. Hope to hear more to come!

What fingering would you suggest for the two condensed versions on the scales?

I have heard that if one doesn't learn music/music theory and continue to practice it from a young age on, that the chances of them ever learning it are pretty small. Do you think this is true? Are my efforts futile? :-)
