Music Lesson 2: Tones, Semi-Tones, and the Major Scale

Now that we have a basic understanding of the Chromatic Scale, lets take a look at note relationships and the Major Scale.

Tones and Semi-Tones

As we move our way up the Chromatic Scale and back down we are moving in a specific order between the notes.  Now, every time you move from one note to another you are moving in what is called an Interval.  The term Interval is just a fancy name used to describe the relationship between two notes.  For this lesson, we are going to focus on two types of Intervals.

The most basic of these Intervals is called a Semi-Tone.  On our Chromatic Scale, we are moving one Semi-Tone at a time (or half step as we called it before) as we move up and down the scale.

Notice, as we discussed in the previous lesson, that as you move up or down the Chromatic Scale you are also moving one fret at a time (this applies to guitars, ukuleles, and any other fretted instruments* such as mandolin).

Now lets double the Semi-Tone.  When you add two halves, you get a whole, right?  (I hope you know this already...)  Well, when we do two half-steps, it becomes a whole step or one step. And when we do two Semi-Tones, we get a Tone.

As we move up or down the neck of our instrument(s), this means we are moving two frets each time.  So, let's try to move from C to C up the neck only in Tones.

Do you see what happened there?  In six steps we got to our next C.  Also, we ended up with a bunch of sharps (or flats depending on if you go up or down).  We haven't really discussed keys yet, but a general rule is that the key of C has no flats or sharps in it.  It's all natural!

The Major Scale

So, we need to make our way from C to C (up and then back again) while doing two things: not hitting any sharps or flats, and using each natural note in the scale.  When we do this, we get the following:

Now, let's compare this to the Chromatic Scale we learned in the previous lesson.

Notice how we skip all of the sharps/flats and move in a specific order.  Let's look at this in relation to Tones and Semi-Tones.

This formula of T, T, S, T, T, T, S is what we call the Major Scale Formula.  Moving in this manner is also called Diatonic.  For now, just think of Diatonic as meaning alphabetical.  Using this formula, you can now start on any note and find any scale!!!

Now, let's relate this to our fret boards.  Here is the C Major Scale on the ukulele and the guitar.

And here is the same scale with us jumping to different strings when we can.

One of the great things about fretted instruments is that you can move things around very easily from one note to another just by shifting to another fret.  With our Major Scale, we need only start at another spot and use the same pattern to generate new Major Scales.  In future lessons, I will show some of the many different scale patterns or fingerings that exist.  These will come in handy.  For now, try to find different ways of fingering different Major Scales up and down the neck.

Note:  For ukuleles, major scale patterns can be a little restrictive in regards to the different ways you can finger them.  This is because most ukuleles are tuned in reintrant tuning and your primary strings for the pattern will be limited to three strings (the C, E, and A strings).  If you are using linear tuning (also known as low G tuning), then it will be easier to come up with multiple Root to Root scale patterns since you now have four strings to work with.  I'll try to shed some light on this in the later lesson.

* Some exceptions of this include mountain dulcimer.  There are others in more exotic music styles that do not follow this rule.  However, in general, this is true for fretted instruments.
