Practical Theory Part 2: Scales

Orville Johnson takes a look at scales in part 2 of his practical theory mini-series.

Taught by Orville Johnson in Beginner Acoustic with Orville seriesLength: 18:40Difficulty: 2.0 of 5

Scene 1: Introduction

Being a beginner guitar player, the huge number of different scales that can be played might be overwhelming. In this lesson Orville Johnson explains how to memorize scales in an easy, manageable way.

The chromatic scale is made up of all twelve notes that are in an octave. Every other scale is just a pattern of different kinds of intervals in this twelve note range. A scale’s pattern remains the same in any key, so the number of scales you need to memorize is already much smaller than it may initially seem.

Half Step (H) – A musical interval equivalent to one fret on the guitar.

Whole Step (W) – A musical interval equivalent to two frets on the guitar.

The most important scale to know in western music is the major scale.

The pattern of half/whole steps for the major scale is: W W H W W W H.

This can be observed in the C Major scale as : C (W) D (W) E (H) F (W) G (W) A (W) B (H) C.

Now you can play a major scale in any key, even if you don’t know the name of the note you are starting on.

Scene 2: Naming Notes

You can easily find the name of any note on the fretboard of your guitar by counting up from the letter name of the open string. Just count up fret by fret remembering these rules:

- When you go up one fret, it is a half step.

- A half step up from a natural note (not sharp or flat) is an “in-between note” that has the same letter name but is sharp (#). Alternatively, it has the next note’s letter name but is flat (b).

- A half step up from an in-between note is another natural note.

- There is no note between B and C or E and F.

You will notice that for most notes on a guitar, there are several different frets that make the exact same note across different strings. A good exercise to help you learn your way around the fretboard is to pick a note and then find the same note on a different string.

You can think of any other scale in western music relative to the major scale by changing the intervals.

A minor scale can be made from the major scale by lowering the 3rd note one half step (minor 3rd).

Here are two different minor scales that Orville demonstrates, relative to the major scale:
1 2 b3 4 5 6 7
1 2 b3 4 5 6 b7

Amazing explanation. Very clear. Congrats for your professionalism and expertise.

Thanks Orville, Awesome way to look at scales. Better than trying to memorize a bunch of box positions all over the neck. I like how you relate them all to the major scale. Eye opening for me. Thanks again,

freefly8freefly8 replied on July 13th, 2017

Wow...again Orville you are great at visual and audio instruction. The scale(s) information was clear and concise. I though about using the fret tags for the notes. I believe I'll try to practice the way you explained it. Thanks once again.

You are a terrific instructor! As a kid that was early diagnosed ADHD, I really struggled to remain attentive in structured learning environments. I really have to drink through the firehouse to remain engaged. However, I find your patient and controlled pace very effective. You teach the guitar the same way I hope to learn and play it, efficient and smooth! Thank you!

NativgodNativgod replied on February 13th, 2017

Love your videos, easy to follow and simple to understand. I am fairly new to theory and I am confused. I thought a half-step was the space between each fret? For example from the 1st fret to the 2nd fret is 1 half-step and 2 (1st fret to 3rd fret) frets is a whole-step. On both your theory lessons you state that there is no half-step between E &F and B & C. Am I wrong?

Another very good lesson. I also like the written summaries that appear below the video. A helpful primer.

So tremendously helpful Orville. Thank you very much! :-)

Orville.JohnsonOrville.Johnson replied on January 6th, 2015

I would just practice major scales for awhile. And remember, there is just one formula for all major scales- whole step-whole step-half step- whole-whole-whole-half. If you start on any note and follow that pattern you'll be playing a major scale. The name of the scale will be the note you start on.

mrousemrouse replied on January 2nd, 2015

Hello Orville- So still a beginner but up to lesson 50 over on Eve Goldberg's lessons. I came across your beginning theory lessons- - is it worth my time learning the major scales now and if so which ones? Or keep on looking at your overviews? I want to learn more theory and play notes and such -Just not sure how far to go in the scale thing right now...Is there a place where you prescribe some specific homework?

guloguloguyguloguloguy replied on November 20th, 2014

I just had a quirky thought: Perhaps it might help someone in trying to visualize, and memorize the "Scale" pattern(s). Imagine running up and down a large set of stairs!....then imagine only stepping on every other step when needing to make a "Whole Step", ....and that means when you step on any two adjacent stairsteps, that That is a "Halfstep"!!! This might take a few seconds of careful visual thinking to get the image into One's "mind's eye", but it might be a useful visual/memory trick to literally imagine running up and down along these steps, until One really 'knows' (memorizes) the "Scale Patterns" well, going UP, or Down!

guloguloguyguloguloguy replied on November 20th, 2014

When writing out the Scale pattern, I like to write/type it as if it were broken into smaller more comprehensible blocks. For instance, the Major Scale could be better written/typed out like this: |W|W|H| W |W|W|H| ...So, One can see that these letters represent the 'relative amount of space', or 'distance between' the actual notes, not the notes themselves directly. It IS a "Pattern" for the Spaces Between the actual notes, of the "Scale" (in this case, it is a "Major" scale. So, I like to use the "slash" mark, or a vertical bar, to show the position of each 'note'. One could use the asterisk *, too. => *W*W*H* W * W*W*H*

guloguloguyguloguloguy replied on November 20th, 2014

I've been wondering if it might not be much more useful to the student, if your second camera viewpoint could be moved, to be in a 'better position', such that it is 'looking downward', = at/toward the fretboard from above!, = closer(more similar) to the position in which the guitar player, and instructor would be looking at/viewing their fretboard, (rather that as it is usually set up as if One was sitting at eye level, in front of and reversed position/opposite to the instructor). [ => Perhaps you should try this and see if it doesn't allow the student to more closely view, and understand more precisely where each fret position, and finger is being located. ] I think that this would be better for all of the JAMPLAY videos (to have that second camera oriented 'from on high', as if from the player's visual perspective)!

Orville.JohnsonOrville.Johnson replied on September 8th, 2014

oakcliffboy- I said the major scale (not chord) follows the WWHWWWH pattern. If you play the pattern you've notated (WHWWWHW) you will not be playing a major scale. If you follow WWHWWWH you can start on any note and that note will be the root of a major scale. hope that helps and sorry for the long delay in replying...oj

oakcliffboyoakcliffboy replied on May 7th, 2014

I don't understand you saying that the major chord follows the pattern WWHWWWH. If I start with D major it is WHWWWHW. Do you mean just the key if C major follows the pattern. Thanks

Great lesson! I am having a great time with the major scale, and you have made it so easy to grasp the other scales as they relate to the major scale. Thanks a lot bro.

Hi, Orville, Started, watching your theory lessons this evening.Took notes what you taught.I will practice to locate notes on fretboard as you adviced.Six strings mean,each note exists 6 times all over the fretbard.No difficulty in understanding two theory lessons.Will watch the rest gradually.Thanks for these lessons.

About Orville Johnson View Full Biography Orville Johnson was born in 1953 in Edwardsville, Illinois and came up on the St. Louis, Missouri music scene, where he was exposed to and participated in a variety of blues, bluegrass and American roots music. He began singing in his Pentecostal church as a young boy, in rock bands in middle school, then took up the guitar at 17,with early influences from Doc Watson, Rev. Gary Davis, Mississippi John Hurt, and Chuck Berry. In the early 1970's, Orville spent several seasons playing bluegrass on the SS Julia Belle Swain, a period-piece Mississippi river steamboat plying the inland waterways, with his group the Steamboat Ramblers.

Orville moved to Seattle, Washington in 1978, where he was a founding member of the much-loved and well-remembered folk/rock group, the Dynamic Logs. Other musical associates include Laura Love, Ranch Romance, File' Gumbo Zydeco Band, Scott Law, and the Twirling Mickeys. Johnson, known for his dobro and slide guitar stylings and vocal acrobatics, has played on over 100 albums. He has appeared on Garrison Keilor's Prairie Home Companion, Jay Leno's Tonight Show and was featured in the 1997 film Georgia with Mare Winningham. His musical expertise can also be heard on the Microsoft CD-ROMs, Musical Instruments of the World and the Complete Encyclopedia of Baseball. He teaches as well at the International Guitar Seminar, Pt. Townsend Country Blues Week and Puget Sound Guitar Workshop.

Orville released 4 recordings in the 1990's: The World According to Orville (1990) Blueprint for the Blues (1998) Slide & Joy (1999) an all-instrumental dobro tour de force and Kings of Mongrel Folk (1997) with Mark Graham. He also appeared on 4 discs with the File' Gumbo Zydeco Band and produced Whose World Is This (1997) for Jim Page and Inner Life (1999) for Mark Graham. In the 21st century, he has released Freehand, a new Kings of Mongrel Folk disc, Still Goin' Strong, and been featured in the soundtracks of PBS' Frontier House and the Peter Fonda flick The Wooly Boys as well as the compilation cd Legends of the Incredible Lap Steel Guitar.

"I feel like a 12 year old kid with a new guitar!"

I am 66 years young and I still got it! I would have never known this if it had not been for Jamplay! I feel like a 12 year old kid with a new guitar! Ha! I cannot express enough how great you're website is! It is for beginners and advanced pickers! I am an advanced picker and thought I had lost it but thanks to you all, I found it again! Even though I only play by ear, I have been a member a whopping whole two weeks now and have already got Brent's country shuffle and country blues down and of course with embellishments. Thank you all for your wonderful program!

"With Jamplay I can fit in a random session when I have time and I can go at my own pace"

I'm a fifty eight year old newbie who owns a guitar which has been sitting untouched in a corner for about seven years now. Last weekend I got inspired to pick it up and finally learn how to play after watching an amazing Spanish guitarist on TV. So, here I am. I'm starting at the beginning with Steve Eulberg and I couldn't be happier (except for the sore fingers :) Some day I'm going to play like Steve! I'm self employed with a hectic schedule. With Jamplay I can fit in a random session when I have time and I can go at my own pace, rewinding and replaying the videos until I get it. This is a very enjoyable diversion from my work yet I still feel like I'm accomplishing something worthwhile. Thanks a lot, Greg
