Section #1: Understanding Notes
Keywords and Topics for this Section
This section is a truncated version of our full guitar notes article. While it gives you all the quick highlights, we recommend referring to the above link for a more in-depth presentation and discussion of the topic.
Guitar Notes for Each Open String in a Standard Tuning
Assuming you're familiar with the basic parts and mechanics of the guitars, let's start with the notes for each open (non-fretted) string.
Here's how the notes would look in a guitar tab and formal music sheet:
Notes and Chords: What They are and How They Relate
Notes are a letter value of a single pitch on the guitar, which can either be an open string (as in the above example) or a fretted note. Those single pitches can be grouped into multiple notes sounding in unison, which give us chords.
For example, the open C major chord is made up of four notes, C, E and G.
Here's how those notes look in a chord chart:
If we pulled these notes out of the chord and played them one at a time (this is called an arpeggio), the notes would show up in a guitar tab like this:
You can checkout the following resources if you need help reading the chord or tab charts:

- Guitar Tab Resource (how to read guitar tabs - near the end of the article)
Now that we've covered some basics about reading notes and interpreting them in a tab and chord chart, we can learn the differences between natural notes, sharps and flats.
Understanding Natural Notes
Natural notes do not have either a sharp or flat attached to them. This means that all natural notes will be displayed as one of the following:
A, B, C, D, E, F, G
We can use the fretboard dots to easily identify natural notes on each string:
In a standard tuning, natural notes occur on the sixth string at the first, third, fifth, seventh, eighth, 10th and 12th frets. The pattern then repeats after the 12th fret.
Here's how it would look on a tab sheet:
Understanding Sharps and Flats
In order to understand sharps and flats, it's helpful to first cover a quick definition of a half step and whole step:
- Half Step: A change in pitch equaling one semitone (one fret)
- Whole Step: A change in pitch equaling one whole tone (two frets)
Changes in pitch are measured in half and whole step increments. Thus, you can understand sharps and flats as the following:
- Sharp: Change in pitch one half step higher
- Flat: Change in pitch one half step lower
This occurs in relation to natural notes. For example, if you start with F and raise the pitch one half step, you get F♯. Likewise if you're looking at B and you lower the pitch by one half step, you get B♭.
On the guitar, naturals, sharps and flats are based on fret position, meaning you've simply got to memorize the pattern. Here's a full chart of the notes on the sixth string:
String-by-String Note Memorization
When it comes to guitar fretboard memorization, take one string at a time and consider the notes at each fret up to the 12th fret. From there the pattern simply repeats. Keep in mind, the pattern is the same on each string, but starts at a different note (per our section on open string notes).
- Starts at E on the sixth and first strings
- Starts at A on the fifth string
- Starts at D on the fourth string
- Starts at G on the third string
- Starts at B on the second string
Thus, the sixth string starts with E and ascends through a pattern, while the fifth string starts at A, ascending through the same pattern, and so on.
Here are the remaining charts for the fifth, fourth, third and second string notes.
A String Notes
D String Notes
G String Notes
B String Notes
Section #2: Understanding Basic Intervals and the Theory of Root Notes
Keywords and Topics for this Section
In this section we'll cover basic note navigation and how to understand what it means when you're moving from one note to another on the fretboard. This will encompass some crucial music theory in regards to the root notes we covered in the previous section. It will show how you're eventually going to use those notes to understand chords and scales.
We'll start with a proper definition of intervals.
What is an interval in a guitar context?
In Music Theory:
The space between any two pitches or notes.
On the Guitar:
The space between any two notes or points on the fretboard.
For example, the following tab is an interval:
These two notes are separated by two semitones which is equal to a whole tone or a “whole step.”
However, guitar intervals don’t always fall on the same string, as the following is also an interval:
Instead of falling on the sixth string - like the previous example - the second note falls on the fifth string at the third fret. We'll dig into this interval more in the "perfect fifth" section.
What are the parts of an interval?
A musical interval is made up of two parts:
- The Root Note: Represents the key of the particular pattern
- The Interval(s): Any note(s) that correspond to a particular root are intervals of that root
For example, a guitar chord is simply a collection of intervals attached to a specific root note.
Take the following C major chord:
C is the root note at the beginning of the interval sequence (on the third fret) while the other three notes are all intervals of the root C. Intervals are always understood in relation to the root note or the lowest note in a given key.
A Guitar Intervals Memorization Chart
There are a total of 11 different intervals before you get to your first octave, which doubles the frequency of the original note. Therefore each interval should have a “Number of Frets” and an “Interval Quality.” Here's a chart you can use to identify interval quality based on fret distance.
Interval Example: What is the perfect fifth?
You might have heard the term “perfect fifth” before and noticed it on the interval chart. This is one of the most important intervals you can learn, as it forms one of the most basic power chord shapes in existence.
You’re almost certain to recognize it.
In this case we have our root G and the interval note D falling seven semitones above the root, albeit on a different string.
That seven semitone spread is what gives us our perfect fifth, making it an extremely common shape. And why is it called perfect? Music theorists have long used the term “perfect” to denote two intervals that were considered to be perfectly consonant.
For this reason a perfect fifth can also be referred to as the “consonant interval” or “highly consonant.”
Section #3: From Root Notes to Power Chords (dyads) to Triadic Chords
Keywords and Topics for this Section
Now that we've covered root notes, intervals and the basic applicable music theory involved with those concepts, we can take those notes and begin building chords. Instead of starting with open chords we're going to start with simple power chord shapes (dyads) and triadic chords since they use two and three-note interval combinations. This is an easier and more logical transition into guitar chords, as opposed to starting with open chords.
We'll start with a quick look at how to read guitar chord charts, then move into two-note power chords which are the pairing of a root and single interval.
How to Read Guitar Chord Charts
In most cases, chord charts use horizontal lines to indicate the six guitar strings and vertical columns to indicate frets, as though you're looking straight down at the fretboard. Blue dots, Xs and Os are used to plot notes, muted and open strings.
Common Power Chord Shapes and Dyads
Dyads or "dyadic chords" are chords made up of only two notes or tones.
In some circles the formal definition of a chord requires at least three notes be present, sounding in unison, in order to be considered a chord. In the first volume of Music: In Theory and Practice, authors Bruce Benward and Marilyn Saker provide the following definitions:
"A chord is a harmonic unit with at least three different tones sounding simultaneously."
"A combination of three or more pitches sounding at the same time."
These definitions are established primarily in respect to triads, which we'll get to in this section. We make room for two-note chords (dyads) as well, partly because of how often you'll use them in real playing scenarios and how easy they are to handle on the fretboard.
As we've already seen, the perfect fifth interval, with its root on the sixth string, gives us one of those dyadic shapes. Here's what it looks like on a chord chart:
Here's another example that utilizes the major third interval instead of the perfect fifth, though keeping with the root G.
Common Triadic Chord Shapes
Technically speaking, a triad is a grouping of three notes that occur in successive third intervals. This means that a triad is made up of a root, a third and a fifth. In his book, Introduction to Music, Ronald Pen describes a triad like this:
"A triad is a chord consisting of three notes built on successive intervals of a third. A triad can be constructed upon any note by adding alternating notes drawn from the scale. In each case the note that forms the foundation pitch is called the root. The middle tone of the chord is designated the third, because it is separated by the interval of a third from the root. The top tone is referred to as the fifth, because it is a fifth away from the root."
Howard Hanson and Carlton Gamer, notable 20th century music theorists, have expanded the definition of a triad to include any combination of three notes, regardless of their interval spacing.
- Harmonic Materials of Modern Music: Resources of the Tempered Scale (Hanson)
- Some Combinational Resources of Equal-Tempered Systems (Gamer)
From a theory perspective, it's good to know the "original" or formal definition of a triad.
However, in practice, we would say it's safe to assume that a triadic chord is any reasonably consonant or harmonious grouping of three notes, which is more in keeping with Hanson and Gamer's assessments. In other words, if you have three notes played in unison and they don't sound completely awful, we could say you have a triad.
Here is a quick example in keeping with the root, third and fifth sequence:
If you want to get into some more dyads and triads before moving onto open chords, you can refer to the following articles which delve into the topic with a lot more depth and detail:
Section #4: Basic Open Guitar Chords
Keywords and Topics for this Section
Now that we've touched on dyads and triads, we can introduce ourselves to the slightly more complex world of open chords. When a chord is called "open" this simply means you're using an un-fretted note (i.e. an open string) to play the chord.
For example, the most commonly known form of C major is, in fact, an open chord:
Let's look at diagrams for the rest of the most common open chords. Refer to the previous section on reading chord charts if needed.
The Open A Major Chord
The Open D Major Chord
The Open G Major Chord
The Open E Major Chord
Basic Chord Changing Drills
Once we've covered these open chords on their own, it's helpful to start learning how to practice changing between them. This is also called chord transitions, which need to be intentionally practiced after individual chords are learned and memorized.
The video lesson from the Guitar Tricks Fundamentals course is a great introduction to chord-changing drills and chord progression practice.

Section #5: The CAGED System
Keywords and Topics for this Section
This section was written by Michael Palmisano, founder of the Guitargate program.
From the simplest chord to the most complicated scale, everything exists in five shapes. To play something in a different key, you can just move the shape. This approach is commonly known as the CAGED system, and when it comes to learning your neck, you can't beat it for simplicity.
Why is it called the CAGED System?
The idea behind this system is that there are five octave shapes and each one relates to a common open chord that we already know. Here we'll go through each pattern based off a particular chord.
PATTERN 1 BASED OFF THE C MAJOR CHORD
PATTERN 2 IS BASED OFF OF THE A MAJOR CHORD.
PATTERN 3 IS BASED OFF OF THE G MAJOR CHORD.
PATTERN 4 IS BASED OFF OF THE E MAJOR CHORD.
PATTERN 5 IS BASED OFF OF THE D MAJOR CHORD.
For example: Play an open position C major chord. In this shape, you are actually playing two C’s. One is the lowest note in the chord played by your third finger on the fifth string. But, there’s another: The note being played by the first finger on the second string.
Isolate these two notes from the chord and play them at the same time. You should be able to hear that they are both the same note (C) but one is higher and one is lower.
Octave C notes within the open C major chord shape.
This is the Pattern 1 octave shape.
Now comes the beauty of the CAGED system: If you slide that whole shape up two frets, you are now playing two D notes in pattern one. Slide the shape up two more frets and you are playing two E notes. One more fret and you’re playing two F notes.
For each chord in the CAGED system, you can follow this pattern.
Section #6: Stretching Fingers and Getting Into Scales
Keywords and Topics for this Section
In this section we're going to start familiarizing ourselves with basic finger exercises and scale patterns. These scales will serve as structural grids that we analyze and memorize so that later we can use them to produce different kinds of creative melodies and harmonies.
Basic Stretching and Finger Exercising Routines
The above video is one of the most straightforward ways to start exercising your fingers for the fretboard, and should be employed at other strings and fret positions. However, you can also use additional interval spacing and patterns to expand on your exercises, which makes the process a little more interesting.
These exercises will also further improve finger dexterity, accuracy and strength.
Based on the Minor Second Interval
This will get you started skipping strings (brings accuracy more to the forefront) and allows you to develop a little bit of speed.
Let’s do a similar pattern, but this time with all four fingers.
Based on the Minor Second Interval
These exercises incorporate two-fret jumps, or more formally, the major second interval. First, something basic:
This is just so your fingers can get used to the interval and isn’t likely to challenge you significantly. Don’t spend too much time on it. To challenge our accuracy we can incorporate a pattern similar to what we used in the first minor second tab.
Let’s add another major second to each line:
Finger selection for each note is important here and, for the first three notes, should go in this order: First - Second - Fourth. So, pointer, middle and pinky finger for the third, fifth and seventh frets. If you aren’t used to this movement, expect it to stretch your fingers a bit. Let’s adjust the shape to incorporate all four fingers.
Combining the Major and Minor Second Interval Exercises
Now that we’ve covered both intervals, as well as some fretboard distance, we can start to run exercises that combine the intervals into three-note patterns. We can start with the following sequence:
Given three notes, we now have two intervals:
- Minor Second: Between the second and third fret
- Major Second: Between the third and fifth fret
Now we can use this sequence to construct our exercises. Here’s what we came up with:
This pattern takes the same sequence of three notes and moves it around to three different strings. Now, instead of jumping from the third to the 10th fret, let’s look at an exercise that let’s us climb there:
You can use the minor and major second interval, as well as the grouping of the two, to build a ton of different exercises at varying fret positions. Take the time to get familiar with these patterns then come up with your own exercises based on the intervals we covered.
Understanding Guitar Scales as a Concept
The most basic explanation of a guitar scale would be the following:
It’s less scary once you realize that in its most basic form a scale is little more than an ascending or descending sequence of notes. Further, these scales are ordered by pitch. Anssi Klapuri, in Signal Processing Methods for Music Transcription, defines pitch as the following:
Pitch is a perceptual attribute which allows the ordering of sounds on a frequency-related scale extending from low to high.
In other words, a scale is an ordered series of notes based on frequency. How do we break this down on the fretboard? Let's start with basic intervals, whole and half steps.
Understanding Whole and Half Steps
We’ve already established that scales are a series of musical pitches. But, how are those pitches understood? In music, pitch is indicated by the first seven letters of the alphabet:
A B C D E F G
Thus, each note (pitch) on the scale will have one of these letters associated with it. Moving between these notes introduces you to the concept of changing pitch, which can be measured in half and whole steps. This is a concept we've already touched on, but here's a more complete and concrete explanation of both half and whole steps:
Half Steps (semitones): If you start with your first finger on the 1st fret of the sixth string (low E) then move your finger up to the 2nd fret on the same string, you’ve moved up in pitch one half step.
Whole Steps (wholetones): If you start with your first finger on the 1st fret of the sixth string (low E) then move your finger up to the 3rd fret on the same string, you’ve moved up in pitch one whole step.
These terms give us a way to describe movement up and down the fretboard, particularly when we’re talking about ascending or descending scales. Thus, scales can be broken down into a mixed arrangement of half steps and whole steps. This is how we constructed our exercises from the previous section.
Consider the following scale diagram:
We’ve circled one half step and one whole step.
Whenever they show up in scales, they make up one and two fret jumps, respectively. If it’s a three fret jump, say the 1st to the 4th fret, we’d call that “one and a half steps.” If it went from the 1st to the 5th fret we’d say “two whole steps.”
Let's look at how these scales fit into the idea of "playing in a key."
Scales and How They Relate to Keys
A musical key can be defined as the following:
The key is the root of the scale that a group of chords or notes fall into. For example, if you have three notes being played, let's say they're C, D and G, we know from the C major scale that this note sequence can be said to be in the key of C.
Thus, a key gives us a scale upon which a piece of music is based.
Let’s talk about this relationship.
What is the link between scales and keys?
We can know right away that our key is going to be one of the seven musical notes.
However, we need to keep in mind that scales are then taken directly out of that key. Thus, it could be said that any piece of music is based off a scale, which has a key. Were we to move the scale up or down the fretboard, the key would change.
Therefore the more correct explanation is that our songs have keys, which then implicate particular scales.
Scales take their letter value from the root note or “tonic” of the scale.
Once you know what scale you’re playing and in what key, you can move the scale or any segment of it to any location on the fretboard, thereby changing its key.
Chromatic Guitar Scales Explained
Western music uses 12 notes which can be referred to as “The Complete Chromatic Scale.” On a keyboard or piano this is represented by seven white keys and five black keys.
On a guitar, it’s represented by those first 12 frets (this is why fretboard note simply repeat after the 12th fret). The chromatic scale on the guitar can be visualized by going from the open E on the sixth string to the 12th fret (high E) on the same string.
Those 12 notes make up the complete chromatic scale on the guitar.
Here, we only go to the 10th fret to save space in the diagram but, the concept remains intact. All the guitar scales you will ever see are derived from this simple 12-note system. All the different sounds, melodies and music notation we get comes from a variation of this sequence.
Now that we've covered the basic music theory involved, we can look at an example of an actual guitar scale that is often used.
The A Minor Pentatonic Scale
The pentatonic scale, regardless of key, is a fairly common pattern, particularly for guitar players. We’ll cover the 10-fret model of the scale, then break it down into smaller chunks. Keep in mind that any segment of the scale can theoretically be moved to any fret.
The dotted blue circles on certain dots signify the root notes at different octaves (which in this case is A). What we want to do now is break the scale down into smaller, more usable segments which can then be memorized and transposed anywhere on the fretboard. We’ll start with the first few frets.
The first segment of the scale falls within the first three frets and the bottom four strings of the guitar. This scale should be handled in three different steps during practice:
- Memorize the pattern as it is
- Memorize the sound
- Transpose the scale to another fret
Let’s say, for example, that you wanted to move the pattern up to the 5th fret. The tab would look like this:
You’re still jumping up one and a half steps for the two lower strings and one whole step for the two higher strings. However, the scale takes on a new key as a result of moving frets. The key of the scale starting at the 5th fret is now D.
Additional Scales to Work On
To expand on what we’ve already covered, we've found the scales listed below to be particularly useful in the following disciplines:
- Blues improvising
- Heavy rock chord pogressions
- Modern pop and rock
- Western music’s dominant intervals and progressions
Most of today’s guitarists make their living in one of these areas or a subset thereof. Go through these scales and take the time to get familiar with both their patterns and sounds. As with the previous example, keys can change with fret position.
1. Basic Blues
2. Major Blues
3. Pentatonic Minor
4. Blues Variation 1
5. Dominant Pentatonic
6. Auxiliary Diminished Blues
8. Pentatonic Major
9. Pentatonic Neutral
10. Melodic Minor
These scales should be viewed as structural, meaning you can memorize them and then use them to build melody, given particular keys and musical styles. In other words, they're constructs and are a means to an end, not an end in and of themselves.
Take the time to memorize these scales so that when you're ready to start building your own melodies, you can draw on what you know about scales and intervals to do so.
Here is some additional material that might be a helpful follow up to this section.
Are these six sections meant to be exhaustive?
Yet, they are properly ordered topical introductions that can give you places to start and a plan to follow. For most beginning guitar players, it takes about six months to get through the topical and memory-heavy parts of learning the instrument.
These sections are a good microcosm of the material that you should be focusing on during that six-month learning period.
Once you get through it, you can then start to apply the different things that you've learned. That's when you start to develop your own style and technique. You've got a solid structure and foundation in place, so now you're ready to start learning songs and getting more creative with your instrument.
