Being a good jazz guitar player means knowing how to practice guitar scales so that they stick in our ears and under our fingers. Having devoted countless hours to this over the years, I have discovered several effective ways to do this which I’d like to share with you in this artcle.

Practicing guitar scales isn’t always the most fun thing to do on the guitar, but there’s no doubt about it, every guitarist needs to know their scales inside out so that they can play what they hear and become better jazz guitarists.

Intervals

 

Playing scales in intervals breaks us out of ‘grid locked’ positions on the guitar fretboard, and helps us understand the imbedded harmony found within each scale on a much deeper level.

To practice scales or arpeggios in intervals, use those which are diatonic to the key. For example, when practicing the C major scale, you wouldn’t use minor 2nds, because you’d get notes that clash against the harmony.

Therefore, I recommend thoroughly learning the appropriate scale harmony before practicing the scale in intervals.

I II III  IV V VI VII
Cmaj7 D-7 E-7 Fmaj7 G7 A-7 B-7b5

 

So, returning to our C major scale, if we wanted to practice this scale in thirds, note that some intervals would be major 3rd while others would be minor 3rds.

Some intervals present challenging fingerings on the guitar (most notably 6ths and 7ths) that we might not use often when improvising, but this exercise ensures we know the scales inside out. By practicing in octaves, we are also developing a great solo technique used by jazz-guitar legend Wes Montgomery.

Once you can comfortably play a scale using a variety of intervals, try and create some lines using a specific interval and take it to a progression or tune you are working on in the practice room.

Here is an example of a ii-V-I line with a specific focus on utilizing 3rds throughout the phrase.

 

 

 

Out of Position

 

While it’s a great idea to practice scales on guitar in positions that fit nicely under the fingers, you can sometimes become lazy and not think about what notes you’re playing, instead relying solely on box patterns to guide your fingers.

One way to avoid this problem is to practicing scales on one string, because you have to think about the notes you’re playing and can’t depend solely on the fingering. As guitarists, we tend to rely on playing vertically on the neck most of the time, which is fine, but we don’t want this approach to become a limitation.

As well as being a good practice technique to learn scales, playing horizontally across the neck is also a beneficial way to practice phrasing. Because you don’t have many notes within reach, you will probably get bored fast and have to find new and interesting ways to use the notes that are available.

My old guitar teacher once told me a story of Mike Stern giving a workshop, where he restricted himself to the top two strings and improvised over “Autumn Leaves” for 10 minutes, and yet he still sounded “just like Mike Stern.”

This exercise also means that we’re often not starting on the root, so we tend to avoid simply playing up and down the scale, which can help further develop your understanding of scale construction.

Here’s how a one-octave C major scale would look on the first string of the guitar, starting on the lowest possible note, E.

Work your way through each string of the guitar in a similar manner. After you can play the scale on each string, try combing two strings before moving on to other keys and scale types, such as melodic minor and diminished scales.

Here’s how the C major scale would look like on the top two strings of the guitar, starting on the lowest note on each string, B and E.

Rhythmic Incorporation

 

When practicing scales, you are working on a number of other items such as technique, theory and dexterity, but rhythm is one element that sometimes get forgotten.

So far all the exercises in this book have been notated in quarter notes for easy readability and clarity, but you should practice every exercise with different rhythms to ensure a well-rounded practice session. Rhythm should be a focus of all your practice room items, including arpeggios, chords, chord progressions and improvising.

Below are some common jazz rhythms that you can use to practice scales. Practice each one separately at first before try switching between two or more different rhythms.

 

 

Once you can play each rhythm comfortably by itself start to combine different rhythms together, and then start to create lines as you did at the end of the interval section of this book.

 

 

Without A Guitar

 

You don’t always need your instrument to practice scales and can therefore practice on your lunch break, in front of the TV, walking through the grocery store etc.

When I first started studying music at college, I quickly had to learn all the notes for each scale and arpeggio in all 12 keys, a highly recommend exercise by the way, and 70% of the shedding for this task was done on the bus each morning as I made my way to school.

Every morning I would think of a scale to work on. Then, I would say the notes in my mind for that scale staring in C, before working through the other 11 keys. By the time I got my guitar in my hands, I already knew the notes of each scale cold, so all I had to do was get the muscle memory down and the scales were learned. Because of my mental shedding, I was able to get the scales down much faster than I had done before.

Key Accidentals Chord Type Arpeggio Scale
C 0 Major 7th C, E, G, B, C C, D, E, F, G, A, B, C
C 1 Dominant 7th C, E, G, Bb, C C, D, E, F, G, A, Bb, C
C 2 Minor 7th C, Eb, G, Bb, C C, D, Eb, F, G, A, Bb, C
C 4 Minor 7 b5 C, Eb, Gb, Bb, C C, D, Eb, F, Gb, Ab, Bb, C

 

Repeat this exercise in all 12 keys, either by saying the notes or writing them down if it helps, before moving on to other scales such as harmonic minor or whole tone. I also recommend modulating between keys in different intervals to get the maximum results from your time in the practice room.

By doing this twice a day, five days a week I had all of the essential major/minor scales and arpeggios mastered in all 12 keys in just under a month.

I hope these exercises have been useful and that you have enjoyed them, how do you practice scales?
