Lesson 9

Picking Single Notes

Music has three components: rhythm, harmony, and melody. We encountered rhythm in Lesson 5, and harmony in the chords we already know. Melody — or the tune — is created by playing single notes.

Key Signatures

We’ve talked about keys, but what do they really mean? In effect, the key tells you the principal notes used in a composition. If a song is in the key of C major, you know that it revolves around the notes of the major scale (although that’s not to say that notes from outside the scale won’t be used).

What Is a Scale?

TIP
This lesson makes use of track 37 on the CD that comes with the book as a backing track for you to play over. Be sure to locate the track on the CD so it will be ready when you need it.

You’ve already encountered the concept of music being in a certain key. In this chapter, we’ll tell you exactly what that means and why it’s so important.

A scale is a series of related notes that follow a set pattern of intervals that are played in sequence from a specified note to the octave of that note. That clear? Well that’s the kind of definition you’ll find in music theory books.

Let’s try to make it a bit easier. Just about everyone in the western world knows a scale, even if they don’t know that they know it. Think of that song from The Sound of Music — you know, the one that starts off, “Doe, a deer, a female deer . . . ” (come on all you Slipknot fans — you know it).

As corny as this song may be, it very neatly teaches the essence of the most important scale used in nearly every form of music. When Maria and the Von Trapps sing “Do-Re-Me-Fa-So-La-Ti-Do,” they are singing the notes of the major scale. It’s such a familiar sound, isn’t it? You get exactly the same tune by playing the white notes of a piano keyboard from C to C.

There are many different scales, but the most common is the major scale. Later in this lesson, we’ll cover the minor scale series. As you will hear, each type of scale has its own unique character when played. The first note of the scale (the root note) signifies the key of the scale.

Scale Degrees

Each note of a scale is given its own Roman numeral, from I to VII. Each of these notes is referred to as a degree. Each degree can also be named. They are:

I — Tonic or root

II — Supertonic

III — Mediant

IV — Subdominant

V — Dominant

VI — Submediant

VII — Leading note

The Major Scale

Every type of scale follows a strict sequence of intervals from root to octave. The smallest interval used in guitar music is a half-step (or semitone, if you’ve been taught the European way). A half-step is an interval of one fret on the fingerboard. An interval of two frets is called a step (or tone in Europe).

In the case of the major scale, the intervals always follow this pattern:

Step; Step; Half-Step; Step; Step; Step; Half-Step

This means that in the key of C, the notes are C, D, E, F, G, A, B, and C.

In the key of C, the eight notes of the scale are C, D, E, F, G, A, B, and C.

Let’s put these ideas into practice now. Try playing the C major scale using the fingering shown below. It can be played from a number of positions on the fret-board, but this open-string version uses only the first, second, and third fingers. The following is an open-string version of the C major scale using only the first, second, and third fingers.

C

Third fret, fifth string

D

Open D (fourth) string

E

Second fret, fourth string

F

Third fret, fourth string

G

Open G (third) string

A

Second fret, third string

B

Open B (second) string

C

First fret, second string

However, using open strings to play scales isn’t always the best idea. Here is another way to play the same scale, this time using only fretted notes. (This will also mean that you have to get the fourth finger of your fretting hand working — not an easy task at first!) By using correct fingering, you should be able to play all of the notes of a scale without having to move your left hand position.

This introduces the all-important “one-finger-per-fret” rule. This simply means that every finger on the fretting hand is used to play JUST ONE of the frets across all six strings. To see how this works, look at the two examples below. You can play the C major scale starting from the third fret of the fifth string. In this case, the first finger only frets the notes on the second fret, the second finger on the third fret, the third finger on the fourth fret, and the fourth finger on the fifth fret.

You can also play a C major scale starting on the sixth string. In this case, the first finger only frets the notes on the seventh fret, the second finger on the eighth fret, the third finger on the ninth fret, and the fourth finger on the 10th fret.

Ascending and Descending

Practice playing your scales in both ascending and descending sequence. In the example on this page, that means starting the descending D major scale on the fifth fret of the third string and working backwards.

Moving the Majors

The advantage to using only fretted notes (not the open strings) in a scale is that your fingers quickly become used to playing a pattern. By moving this pattern along the fingerboard, it becomes possible to play these scales in any key.

For example, if you shift all of the notes of the C major scale up by one fret, you have a major scale in the key of C sharp (or D flat). You’ve played the same pattern of notes, but your hand has merely shifted an inch or so along the fingerboard. So if you learn the two patterns shown above, you can easily play major scales in any key.

To show you how easy it is, let’s bring in the new backing. This is a simple repeating sequence that plays the chords C major, D major, F major, and G major each in two-bar blocks. Your task is to play a major scale over each chord (in the correct key, of course).

  • C Major

Use the second scale from the previous lesson — the one that starts on the fifth string and uses only fretted notes.

  • D major

To play a D major scale, play the same pattern as C major, only shift the whole pattern up by two frets. You’ll find the scale diagram on page 216 of your textbook.

  • F Major

Although you could use the same pattern played from the eighth fret of the sixth string, for a bit of variety, lets use some open strings. When you do this, make sure that the notes played on the first fret are fretted by the second finger — although the first finger does not fret the open strings, it is in place for when the pattern is moved up to play a G major scale. The fingering diagram for the F major scale is on the bottom of page 216.

  • G major

Move the previous pattern up by two frets so that it begins on G, the third fret if the sixth string. The diagram is at the top of page 217.

No Escape

There’s no denying it: learning scales can be DULL. Still, it is important to have at least a rudimentary knowledge of how they work. Understanding scales and the way that notes relate to one another will help you understand how harmony and melody work. From there, you can learn how certain combinations of notes work well together. All of this is invaluable for songwriters, composers, and the soloing guitarist. For more on scales, see Chapter 15 of the K.I.S.S. Guide to Playing Guitar.

Minor Matters

The minor series is the other significant scale system used in most musical genres. The principle difference between a major scale and a minor scale is the interval between the first and third notes. On a major scale, the interval is a major third (four frets on the fingerboard); on a minor scale, it is a minor third (three frets on the fingerboard).

To make things more complex, there are three different kinds of minor scales.

Natural Minor

The most common minor scale is called a natural minor scale. It has the following intervals from the root:

  • Step; Half-Step; Step; Step; Half-Step; Step; Step

In the key of C, the notes are C, D, E flat, F, G, A flat, B flat, and C. The fingering pattern for the C natural minor scale is on page 219 of the course textbook.

Harmonic Minor

The harmonic minor scale differs from the natural minor in that the sixth note is sharpened (raised by a half-step). This change creates an alteration to the flavor and flow of the sound. The notes on the harmonic minor scale have the following intervals from the root to the octave:

  • Step; Half-Step; Step; Step; Half-Step; Step+Half-Step; Half-Step

In the key of C, the notes used are C, D, E flat, F, G, A flat, B, and C. The fingering pattern for this scale is on page 220 of the course textbook.

Melodic Minor

The final member of the minor scale series is the melodic minor. It differs from the natural minor in that the sixth and seventh notes are raised by a half-step. The melodic minor scale is created using the following set of intervals:

  • Step; Half-Step; Step; Step; Half-Step; Step; Step; Half-Step

In the key of C, this uses the notes C, D, E flat, F, G, A, B, and C. To play this scale, the one-finger-per-fret rule has to be compromised: you have to use the first finger to cover the notes on the fifth and sixth frets. The fingering pattern for this scale is on page 221 of the course textbook.

Additionally, when you are playing a descending melodic minor scale, the intervals revert to those used by the natural scales. If you descended with the same notes of the melodic minor as you used in the ascending scale, the minor “flavor” of the sequence would be lost.

Contrasting the Four Scales

Moving Forward

Now you’re familiar with the necessary evil of scales. In the next and last lesson, we’ll cover the bar chord. As long as you learn a few basics, bar chords can make guitar playing easy, fun, and quick. Be sure to do your homework!

Assignment : Scales

You guessed it. Try your new picking abilities out on the scales. Practice, practice, practice. The lesson describes major and minor scales, so try them both. Chapter 15 in your textbook, “Getting to Know Chords and Scales,” has all the fingering diagrams for the scales you need to learn.
