Intermediate Theory Lesson – Understanding Major Keys Quickly and Easily

In Music Theory | on December, 03, 2009 | by | 25 Comments

This lesson is a quick tutorial on understanding and applying major keys. It is essential for every musician of every level to know what is covered in this lesson.

The material found in this lesson will form the backbone of all of our scale studies here at GuitarLessons365, so it would be a good idea to download the PDF and learn it.

The method used here to get you comfortable with keys is very simple and quick. However, the idea is not to try and figure out keys as quick as you can with this method. Take your time in learning and saying all of your major scales.

When it comes to actually applying this material in a real life situation, you won’t be using any method because hopefully by that time you will just know your keys automatically.

So this tutorial is really just a way to get these keys in your head so you can begin to become so familiar with them that eventually you won’t have to think about it anymore.

THAT is when you will truly have your keys nailed, and it only comes from a methodical study of the keys over a short period of time.

No video for this lesson, since its all bookwork.. WooHoo!!!

So Good Luck and let me know if you have any questions!!

I already knew most of this content from playing piano, but I see how much more applicable learning scales is for guitar! It’s good to have my memory refreshed with this lesson. Thanks!

Thanks for checking it out Chris, I have a lot of chord progression and theory lessons available here on the site. Perhaps you can refresh your memory with some of those as well. :D

hey Carl, mate i always think in minor key does this make me odd?.if some 1 says its in c major my brain thinks A minor.Does it really matter?.I found reading the pdf confusing is this just cause im a theoretical noob?
keep up the good work

I don’t think that is totally bad at all. The great Pat Martino usually see’s everything as minor as well. However, in most theory circles the major scale is considered the foundation of western music, so I use that as the basis for all visualization. Since every minor key and mode has a parent Major Scale, I feel it is the most consistent way of visualizing the fretboard. It becomes very easy to take every mode in music and reduce it to it’s parent scale for visualization purposes. The minor scale is one of those modes so I just personally feel it makes more sense to streamline everything down to something that they all share which is a Parent major scale. Hope this make sense!! Cheers.. Carl

demystified!! thanx a ton man!!

All due respect, I’m hoping by the end of this that I will have brought to the surface what perhaps some others who are new to this strange way of looking at music or those who have have been feeling like me but haven’t been able to put it in words.

As an introduction, I’ve done music for all my life (you could say), but definitely over 20 years, singing, guitar, piano, and just about anything I could pick up, even rocks. But, all my life, I’ve never just sat down and learned music theory.

Bear with me a moment. I WANT to understand it so I beg you, don’t take my banter as something that is invalidating all that you have done (which is great) or all that you’ve learned, the experiences you have gotten or the success you have been given.

I’ll be honest, having talent in singing, guitar and songwriting has been frustrating when it comes to people who know theory. I feel pretty stupid when they talk as if they know my music better than myself. At the same time, I have met and know friends and associates who know music theory up and down but suck at playing, singing… or worse, don’t even play instruments at all!!

Deep inside my mind, some part of me doesn’t see the point or the practical application when I sit down and play my guitar. I write good songs, I sing wonderfully, I have relative pitch that could be developed more if I worked at it. I probably know more theory than I give credit because I’ve done music so long, but I couldn’t put a name to any of it. I can play a 3 note per string major scale on a guitar ONLY because I know the finger patterns. Over time, I have learned to shift that scale around the neck and connected that pattern that to other scales that interrelate to each other all over the neck. I did this without theory, just my ear, my guitar, a big chalkboard and a lot of patience.

The way I compose is as such, while I noodle around, I find something that sounds meaningful, communicates to me, begs to be created. Why do I care to assign a letter or name to it or what mode it’s in! If I then find another riff and it sounds good with the first one, someone with the theory might say, “Neat! You used a combination of [insert technical music theory babble] that’s really hard to integrate and you pulled it off! And I say, “I really don’t know dude, I just like the way it sounds.”

You and I certainly know great guitar players that don’t know a bit of music theory and create amazing stuff, yet said persons couldn’t name all the notes in every scale, and perhaps can’t even tell you how many sharps & flats there are even in what they are playing on the guitar neck.

So, in closing, let’s say I learn all the sharps and flats and I have learned how to create a minor and major scale in my head or on paper. But, I still have to learn *all* the notes on the guitar to really apply those scales and if I do, when it comes to writing a song, I’m not going to just sit there and count all the notes I play and make sure they are in a scale, or analyze what I play so that I can loft-fully say, “Oh, I wrote this using a mix of this node and that key”. And I’m sure you’ll agree, so that leads me to my original point. What is the purpose?

In closing: I admire people who learn theory and so can you please show me how you think learning this really translates to playing better guitar? What is the GAP that is filled from learning theory to sitting down and playing and being a better player or songwriter? If you play Little Wing, are you thinking of all the theory behind it? Was Jimmy? Wasn’t he stoned and high, getting his riffs and ideas from beyond the ether? I know he was trained, but did he really take such a rigid approach to writing music? HELP ME UNDERSTAND how these pieces fit together.

Gratefully,
Andy

Update to my last post. I took the time to understand keys, and quickly moved to playing Major modes. Let me say, my solo/improvising has catapulted into a whole new realm. I’ve been toying with all the modes for a week now and I’m finding all sorts of cool patterns. My favorites so far are Lydian, Mixolydian, and my all time aural delight, the Aeolian. Locrian has been tough, trying to make it sound good, but it has its moments.

So, if anybody wonders, “Why learn music theory when I can play by ear?”, I’d say, because it provides a structured way to approach the relationships between melodies, not merely getting ‘nerdy’ with music. Once you have a knowledge of those fundamentals, you can return to being creative with a new palette of options and you’ll have that added advantage, knowing WHY you sound the way you do. It’s not as complicated as it may seem. Playing the guitar while you read the lessons helps you realize what you’re learning and perhaps that a lot of what you’re learning, you already knew. The added benefit is the ability to communicate your playing with someone else.

Thanks for your lessons. They are simple and effective.

I am having a hard time with this stuff, I guess I think all scales really are the major scale and i understand relative minor so I just see it that way.
All scales come from the major scale, I will keep trying Andy seemed to get it in a few days.
I have seen a change in my playing as well, I play a lot of stuff you hear on the radio so It seem, Ionian and Mixolydian and Aeolian are use in my playing and in most pop rock and country stuff.
Some times your solos come right from the chord shapes or tones.
I would like to plug Hendrix, he was high, too high in his solo act, but the man or boy played with so many greats of his day.
I have been playing longer than this man live on this earth, he had an old soul
Every guitar player alive today, well rocking players steals a lick from this Man.
Stevie Ray Vaughn did it like note for note but in another key and people think its his lick.
I have seen him play right handed guitars, stung for right handed players.
I think he could play any thing with a string, saw the man play a fiddle once.
He had big hands used his thumb and little finger for chords, which he got from Jazz greats of his day.
Got to plug Peter Green to, but Hendrix change the way we look at music so even if you don;t think his soloing is all that great, it was at that time.
I am going no where , I will stick with this training,it is needed and i wish I could have got it 20 years ago.
People are different, it my take ten weeks or ten months ANdy got it in ten days.
Carl seem to have a knack at teaching, this stuff is cracking my hard head, I think I will always think this is all the major scale I can’t get it out of my head but it is cool to try to re-learn stuff I really should have stuck with.
I dated a girl once she had a degree in music but had very little else , she really was a bad musician, if I didn’t see her degree I would not have believe it.
Thanks again to Carl Brown for making this site

Steveo my fellow axe-man, you must get out of that comfort zone. You can thank yourself later.

12.03.09

I have been playing guitar for over 40 years — but mostly just chords — and really knowing little music theory. As one guy at another site expressed it “a singer who also plays guitar” .. he had expressed the desire to get to “a guitar player who also sings”. Never want to give up singing but would really love to improve my guitar playing.

Imagine after all of these years to be given something that will help me to remember how to determine things about a key without looking at a book. “UNDERSTANDING KEYS” is a great resource. I did find the last paragraph a bit more difficult to follow than the rest but all in all I was eventually able to figure out what you were saying.

Thank you so much.

I have taken some online courses and actually started guitar lessons with a teacher on three different occassions (three different teachers) as well as purchased some courses over the internet. But it is always starting over. And the depth of theory is usually what notes are on each string and not really getting to music theory — like I would like to understand how to put together a guitar chord — and when someone on our worhsip team calls out “key of G” for this song, I would like to know what to do — if I don’t have the chords in front of me or can clearly see where someone else’s hand is on the guitar, I am lost.
Probably a lot to ask. But really what a lot of courses appear to promise .. but so far don’t deliver.

I expect that if other stuff on your site is this good that I will want to contribute financially to your site from time to time but prefer a one time payment to a monthly withdrawal. Is there any way to do that? It is just that for other sites, the only way to stop an automatic monthly payment was to contact the credit card company. That is not desirable.
Some places allow a monthly fee or annual fee or in some cases a lifetime fee.

Once again, thanks.

I was just wondering something thats very confusing to me. I am trying to take in the key theory for figuiring out which keys have what sharps and flats. I’m catching on but here is my question. as far as I know there is no B# or E#. If you look at a piano it seems clear to me. I dont understand how you can have these in C# major or F# major which is shown in the PDF. Can some one open my eyes.

Thanks
Charles

12.03.09

Hey Charles, great to hear from ya. :D Let me see if I can try and help you out a bit.

Let’s start by just stating this simple rule. Every major scale has only seven notes in it and those seven notes can never share the same alphabet letter. We have 7 different letters in the alphabet that we use in music A B C D E F G. Every single major scale uses all seven of those letters once and once only.

So if we have the key of C# major for instance. C# D# E# F# G# A# B#, you can see that we used one of each of those seven letters. The easiest way to understand why I didn’t call B# and C is because we have already used that letter name once in the form of a C#. You can’t have a C AND a C# within the same key so we simply make the B a B# and call it a day. :) .. The same goes for the E# in the key of F# major. We obviously can’t call the E# an F since we are already using the letter F in the form of the F#.

Hopefully this will clear it up a bit for you. I know this can be a little difficult to understand, but after you get it you will see just how much simpler it is to call something a B# or E# than to have two notes that share the same letter within the same scale.

Let me know if you need more help!!

Happy Holidays!! Carl..

12.03.09

Thanks Carl. I just started using the site and love it. Thanks for clearing up my confusion. It makes perfect sense now. I can move on now. Ya! I’m sure I will need you again so stay tuned.

Happy Hollidays

Great, I will stay on call for whenever you need me. :D

12.03.09

hi Carl
this Soumojit, before i wud write my query I must say here that u hve really good ear & playing ability. i also practicing regularly but not very good in music theory area. i want to how can I connect major chord notes with minor notes. Like if I am playing a music part in G key & if some where any minor chords reqd to placed then what will be that note or area, like in G major scale Em, Am, Bm, F#m chords will come but when i wud try transcribed a lesson how I will apply them.
pls reply soon because it is not able to sleep at night.

Regards
Soumojit

12.03.09

Hey Soumojit, I hope I understand your question correctly in that you want to be able to play a chord progression in any different major or minor key.

If that is the case, after you have gone through the “Understanding Major Keys Quickly and Easily” lesson you should then take a look at the “Creating Major Key Chord Progressions” lesson. Then after that you should go to the “Understanding Minor Scales” lesson followed by the “Creating Minor Key Chord Progressions” lesson.

Hope these lessons will answer your questions. They can all be found in the Music Theory Archive. It will take a while to absorb all of the material so just be patient. :D

Thanks!! Carl…

It’s been said before these lessons are simple and effective. Music theory is tough, but with a good teacher it really makes sense. My 2 cents worth is that if you are having a problem remembering the order of sharps and flats, the way I learned it, childish or not, is BEADGCF Bug Eyes Are Darn Good Cat Food. And FCGDAEB Fat Cats Get Down At Eds Bar. It made it easier for me to remember than just thinking of letters or that they are 4ths and 5ths.

12.03.09

Hey, definitely digging how big of a help this site is just to let you know. Haha, but anyways as a new guitar player I definitely understand keys now after reading the PDF. It’s amazing how simple you made it seem, through my own mind I couldn’t comprehend what people have been saying about Keys. Haha.

Also big question here. Does determining the key determine what chords will be played in a song and if so determine the fingering position of those chords?

12.03.09

Hey Kim, it does determine the chords that will be used in the song, even though the chords you will see will not always fit nicely into the original key due to a change of key within the song or other things like modal borrowing.

But for the most part, understanding the key and its corresponding chords should give you a much better idea of what is going on with the music. :)

Cheers! Carl..

Treaure !

Love the simplicity of this lesson. I’ve never really gotten into the basics, and I must say this is a very simple way to memorize this stuff.

12.03.09

Hey Carl, this is really good stuff! Really, but I need some clarification on this: C# Major: F# C# G# D# A# E# B# – this scale is spelled with B# as the last note and I always thought that B# was C… so when I read the lesson on minor scales and spelled out all of my relative minors I got to this scale and it occurred to me that I should probably ask for clarification on it. Can you tell me what the deal is with this spelling? I really needed the lesson, though. Thanx!!!

12.03.09

Hey Edgar, I would be happy to clarify. The note B# is indeed the same as the note C, but in a C# Major scale it is spelled as a B# because no key can have two of the same letter name.

In other words, every major scale and minor scale has only one each of the seven letter names in music A B C D E F G. That is why they are all 7 notes. In the key of C# major we already use the letter name C with the C# note(root of the key). Therefore, we have to spell the last note in the scale as a B# to make sure there are no confusing double letter names like (C# D# E# F# G# A# C)… That would be a very confusing way to spell the key. If you ever take a look at Key Signatures check out the key of C#. You will notice that a # is placed on the B line indicating that the note is spelled as a B#.

Hope I didn’t confuse you any further. LOL.. Thanks for checking out my lessons!!

Cheers! Carl..
