Constructive Noodling: Using Improvisation to Learn the Guitar Fretboard

In all my years teaching guitar lessons, to players of all background and skill levels, the most common question I get asked is, “How can I memorize and visualize all of the note names across the fretboard?”

Knowing each note on the guitar is an essential skill that we should all tackle at some point in our development, the sooner the better for most players. While playing up and down scales, naming notes as we go along, and other memorization techniques work for some people, for others these types of exercises can be boring, causing some of us to stop the note learning process all together.

One of the things I’ve done over the years when teaching note names on the guitar is to incorporate improvisation into these exercises, mixing in fun and creative stimulation to the often tedious task of learning each note on the guitar.

Below are four of my favorite exercises that you can practice in order to learn the names of each note on the guitar, while having fun and improvising at the same time.

You won’t have to do all of these exercises, or even one for long periods of time. Often, a few weeks or a month of doing these exercises for a few minutes a day is enough to get the names of each note learned, or getting the skill of finding each note name to the point where it begins to develop naturally in your playing.

Check these exercises out. They will help you in developing your fretboard knowledge, while getting your improvisation chops moving forward at the same time. A win-win if there ever was one.

Since the examples for this exercise are rather long, and to give you the chance to print them all out in one file if you want, I have created a PDF for all of these exercises that you can download onto your computer.

In this PDF you will find each exercise mentioned below, as well as all the chromatic notes written out on one string at a time for easy reference. In this section, you will notice that I’ve written #’s ascending and b’s descending. This is to ensure that you see both sharps and flats on the guitar, and you can learn the relationship between # and b notes, such as F# being the same note as Gb and so on.

Enough talk, on to the exercises!

1 String Scale Improvisation

The first exercise we will look at is learning, and then improvising with, scales on one string at a time. In this exercise, the goal will be to learn the notes on one string, in multiple keys, while keeping things exciting with improvisation.

Here are the steps to running this exercise in the woodshed:

Pick a key, for this example we will use C Major (C D E F G A B C)

Find the notes from this scale within the first four frets of the guitar, in this case it would be E (open), F (1st Fret), G (3rd Fret).

Play the notes while saying them out loud until they are memorized.

Improvise with these notes while saying each note out loud when you play it. You can use a metronome here if you are comfortable enough, or a Band in the Box Cmaj7 vamp. If you are finding that this exercise is tricky at first, practice it without any time or tempo. Then, once you get the feel for it you can bring the metronome or a playalong into the mix.

Repeat this process between frets 5 and 8. For the key of C major these notes would be A (5th Fret), B (7th Fret) and C (8th Fret)

Repeat this process between frets 9 and 12. For the key of C major these notes would be D (10th Fret) and E (12th Fret).

Once each position is comfortable you can mix them together, starting with two positions and then all three combined.

Do these same exercises with different keys as well as on all the different strings. Not only will you be able to learn the notes on the neck, but you are improving your skills as an improviser at the same time.

To help you get started, I have written out the notes on the accompanying PDF for the C Major scale on each string as a reference. You can build the other keys from here after you’ve worked through C on each string, one at a time.

When moving from key to key using this exercise I find that moving in these two directions is the most helpful, either adding one sharp or one flat to the next key in the chain.

Order of Sharp Keys

C None
G 1 Sharp F#
D 2 Sharps F# C#
A3 Sharps F# C# G#
E 4 Sharps F# C# G# D#
B 5 Sharps F# C# G# D# A#
F# 6 Sharps F# C# G# D# A# E#
C# 7 Sharps F# C# G# D# A# E# B#

Order of Flat Keys

C None
F 1 Flat Bb
Bb 2 Flats Bb Eb
Eb 3 Flats Bb Eb Ab
Ab 4 Flats Bb Eb Ab Db
Db 5 Flats Bb Eb Ab Db Gb
Gb 6 Flats Bb Eb Ab Db Gb Cb
Cb 7 Flats Bb Eb Ab Db Gb Cb Fb

You can use this ordering for any exercise in this article, moving to the next key by adding either one sharp or one flat. It will allow you to slowly work your way through all of the notes in the chromatic scale, while at the same time you can learn the key signatures for every major key.

1 String Triad or Arpeggio Improvisation

One of the variations that I like to do with the first exercise is use triads or arpeggios instead of scales when learning the notes on one string. So, instead of playing the notes of the C major scale on one string at a time, while saying each note out loud, you can play the notes of the C major triad, or the Cmaj7 or C6 arpeggio.

Since there are fewer notes in a triad and arpeggio than the scale, you don’t have to divide the neck up into three sections as you did with the previous example.

This exercise is a fun one because there are so many triads and arpeggios to choose from, especially when you get into different keys, that you can always find new keys and new chord qualities to practice.

To help get you started with this exercise, I’ve written out the notes for the Cmaj7 arpeggio (C E G B) on each string in the accompanying PDF. Use the same approaches as the first exercise with these notes.

Using one string at a time, play the notes while saying them, then improvise with them, and then move on to different strings, different keys and different chord qualities. I recommend starting with Maj7 arpeggios, then doing 7th arpeggios, m7th arpeggios, m7b5 arpeggios and finally diminished arpeggios to ensure that you cover all the bases.

Use Octaves to Learn Note Relationships

One of the easiest ways to start to see notes across the neck is to learn how the interval of an octave is laid out along the fretboard. Here is an easy reference and guideline to finding the same note, one octave higher, starting on each string.

6th String: 2 frets over and 2 strings up, so F on the 1st fret of the 6th string can be found one octave higher on the 3rd fret of the 4th string.

5th String: 2 frets over and 2 strings up, so F on the 8th fret of the 5th string can be found one octave higher on the 10th fret of the 3rd string.

4th String: 3 frets over and 2 strings up, so F on the 3rd fret of the 4th string can be found one octave higher on the 6th fret of the 2nd string.

3rd String: 3 frets over and 2 strings up, so the F on the 10th fret of the 3rd string can be found one octave higher on the 11th fret of the 1st string.

Knowing this information, and visualizing octave relationships on the guitar, can really help to open up the names of each note that you are playing.

Again, just learning these notes by wrote can be boring, so use the improv exercises from the first section of this article to spice things up.

Play the notes of the C major scale on the 6th string in octaves until you have it memorized. Then, improvise with these notes, saying the names of the notes out loud as you play each one. When you can do this, take the exercise to the other strings and then to other keys in order to cover all the bases.

To get you started, I’ve written out a few examples of this approach in the accompanying PDF. The first example shows you how the note F can be found across the entire neck using this technique, and the second lays out the notes of the C major scale in octaves across all the strings.

Take your time with this exercise. Not only do you have to think of the notes that you’re playing, but there is a bit of a technical challenge to this approach when you play two strings at one time. So, there is no hurry to race through this, or any exercise, slow and meticulous is always better than rushing through and not learning things fully.

Improvise In One Key Across Entire Neck

The last exercise in this article is one of my favorites. Once you have a decent handle on finding the notes on the neck, you can improvise in one key without the limitation of one string at a time.

This might be a bit advanced for beginners, since you will have to know all the notes of any key across the entire neck, so if it sounds tough you can divide the neck up a bit at first, and then connect these sections to form the entire guitar.

Here are the steps to playing this exercise in its entirety:

Pick a key, for example C major

Visualize the notes of the scale across the neck

Slowly start to improvise, saying each note, using only C major

Resist the urge to use box patterns or other shapes, unless you can name each note in that shape as you play it.

Try to move around the neck as much as possible. If you find yourself in the lower four frets for a while, purposefully move to a different part of the neck. The goal is to be able to move across the neck with ease in any key, knowing the names of the notes, without relying on scale or arpeggio patterns to get you there.

Repeat these exercises with different tempos.

Repeat these exercises with different keys.

If you like this exercise but find it difficult to do right away, you can divide the neck up into sections to make it easier at first, then bring them together to form the entire neck.

So, you could do the above exercises within the first four frets, then between frets 5 and 8 and finally between frets 9 and 12. After you are comfortable with one key in each area, try connection two sections and finally all three together. Then move on to faster tempos and different keys.

Learning the names of the notes on the fretboard is an important skill, but one that can be a boring and tedious task to learn. By using exercises that mix improvisation with learning the names of each note across the neck, you can not only become more confident with your knowledge of the instrument, but have fun doing so at the same time.
