For this new topic, I’m gonna be giving yall some different ways to look at chords. In part 1, I’m going to explain how you can tell what quality (major, minor, aug., dim.) a chord is just by looking at it. To make things easier, I’m gonna use white-note chords. Also, I’m only going to deal with 3-note chords here because this is the foundation for all the other chords.
On a side note, my theory teacher taught me using this method, and it really opened up my understanding of chords. Hopefully, it will do the same for some of you out there.
Before I begin, let me review how to form a chord. The easiest way to explain this is to first pick a note, then hit every other note after it. So, if C were your first note, it would look like this:
C D E F G A B C D E F G A B
You see the big red notes? That’s how chords are formed. I also need to review accidentals. These are your sharps, flats, and naturals:
Natural - this is basically a white note; any note name that is by itself is a natural note
C = C natural E = E natural
Flat (b) - this means to lower a natural note 1/2 step
Cb / C flat = C lowered 1/2 step Eb / E flat = E lowered 1/2 step
Sharp (#) - this means to raise a natural note 1/2 step
C# / C sharp = C raised 1/2 step E# / E sharp = E raised 1/2 step
Now that I’ve reviewed all that, one more thing is I'm going to be using a term called root notes. This is just another way of saying natural notes, notes with no sharps or flats beside them. O.K., let's get this thing started now:
3-note chords built off C
C-E-G
This is the first 3-note chord built off C. This chord is called C major. Now, let’s take a closer look at this chord, specifically the individual notes. Notice that not only are all those notes white notes, each note also “looks” the same as each other. What I mean by that is each of those notes are natural notes. C natural + E natural + G natural gives us a C major chord. Now, let’s see what happens when I change something:
C#-E#-G#
Now, can u tell just by looking what quality chord this is? If u can, that’s great. If not, let’s take a closer look at it. Now, when I look at this chord, the 1st thing I see is they all have sharps by them. Since they all have sharps by them, that means they all look the same. Hmmm, doesn’t this sound a little familiar?
Remember how in the C major chord all the notes looked the same. What quality chord was that? You guessed it, MAJOR. Guess what, using the same principle as we did with C-E-G we can also say that this chord, C#-E#-G# is indeed a major chord. Isn’t that neat? The name of this chord is C# major. Let’s do one more to drive the point home:
Cb-Eb-Gb
I’m sure by now most of you have caught on to the pattern. Just in case u haven’t, let’s take a closer look at this chord. Once again, I see that all the notes look the same. This time, they all have flats beside them. Gee, I wonder what quality chord this is? That’s right it is also a major chord. This chord is called Cb major.
The whole point of this is no matter how many sharps or flats are present, as long as the root notes are C-E-G and there are the same number of sharps or flats beside each of them, it is a major chord.

C-Eb-G
This is the second 3-note chord built off C. This chord is called C minor. Now, let’s take a closer look at the notes of this chord. Notice that not all those notes are white notes. We now have a black note present, which means that this time each note does note look the same as each other. The E note has been lowered by a 1/2 step. So, now the two outer notes look the same, but the middle note is a 1/2 step lower than the others. Now, we have C natural + E flat + G natural gives us a C minor chord. Now, let’s see what happens when I change something:
C#-E-G#
Now, can u tell just by looking what quality chord this is? If u can, that’s great. If not, let’s take a closer look at it. Now, when I look at this chord, the 1st thing I see is they don‘t all look the same. So, we can immediately say this isn’t a major chord. The next thing I see is the middle note doesn’t have a sharp beside it, it has a natural. That means that it is a 1/2 step lower than all the other notes. Hmmm, doesn’t this sound a little familiar?
Remember how in the C minor chord the two outer notes looked the same, while the middle note was a 1/2 step lower than the others. What quality chord was that? You guessed it, MINOR. Guess what, using the same principle as we did with C-Eb-G we can also say that this chord, C#-E-G# is indeed a minor chord. Isn’t that neat? The name of this chord is C# minor. Let’s do one more to drive the point home:
Cb-Ebb-Gb
I’m sure by now most of you have caught on to the pattern. Just in case u haven’t, let’s take a closer look at this chord. Once again, I see that all the notes don’t look the same. It is very evident here because one of the notes has two flats beside it. Don’t be alarmed, the name for notes like this double-flat (lowered two 1/2 steps) I also see that the two outer notes look the same, while the middle note is a 1/2 step lower. Gee, I wonder what quality chord this is? That’s right it is also a minor chord. This chord is called Cb minor.
The whole point of this is no matter how many sharps or flats are present, as long as the root notes are C-E-G and the two outer notes look the same while the middle note is a 1/2 step lower, it is a minor chord.

C-Eb-Gb
This is the third 3-note chord built off C. This chord is called C diminished. Now, let’s take a closer look at the notes of this chord. Notice that not all those notes are white notes. Now, we now have 2 black notes present, which means that this time each note does note look the same as each other. The E note has been lowered a 1/2 step and the G note has been lowered by a 1/2 step. So, now the last two notes look the same, but the first note is a 1/2 step higher than the others. Now, we have C natural + E flat + G flat gives us a C diminished chord. Now, let’s see what happens when I change something:
C#-E-G
Now, can u tell just by looking what quality chord this is? If u can, that’s great. If not, let’s take a closer look at it. Now, when I look at this chord, the 1st thing I see is they don‘t all look the same. So, we can immediately say this isn’t a major chord. The next thing I see is the middle note doesn’t have a sharp beside it, it has a natural. Also, the last note doesn’t have a sharp beside it, it also has a natural. So, we can immediately say this isn’t a minor chord either. Here the first note is a 1/2 step higher than the others. Hmmm, doesn’t this sound a little familiar?
Remember how in the C diminished chord the last two notes looked the same, while the first note was a 1/2 step higerer than the others. What quality chord was that? You guessed it, DIMINISHED. Guess what, using the same principle as we did with C-Eb-Gb we can also say that this chord, C#-E-G is indeed a diminished chord. Isn’t that neat? The name of this chord is C# diminished. Let’s do one more to drive the point home:
Cb-Ebb-Gbb

The whole point of this is no matter how many sharps or flats are present, as long as the root notes are C-E-G and the last two outer notes look the same while the first note is a 1/2 step higher, it is a diminished chord.

C-E-G#
This is the fourth 3-note chord built off C. This chord is called C augmented. Now, let’s take a closer look at the notes of this chord. Notice that not all those notes are white notes. We also have a black note present, just like with the C minor chord. This time the G note has been raised by a 1/2 step. So, now the first two notes look the same, but the last note is a 1/2 step higher than the others. Now, we have C natural + E natural + G sharp gives us a C augmented chord. Now, let’s see what happens when I change something:
C#-E#-G##
Now, can u tell just by looking what quality chord this is? If u can, that’s great. If not, let’s take a closer look at it. Now, when I look at this chord, the first thing I see is they don‘t all look the same. So, we can immediately say this isn’t a major chord. It is very evident here because I see that one note has 2 sharps beside it. Don’t be alarmed, the name for notes like this is double-sharp (raised two 1/2 steps). The next thing I see is the first 2 notes look the same, while the last note seems to be a 1/2 step higher than the others. Hmmm, doesn’t this sound a little familiar?
Remember how in the C augmented chord the first two notes looked the same, while the last note was a 1/2 step higher than the others. What quality chord was that? You guessed it, AUGMENTED. Guess what, using the same principle as we did with C-E-G# we can also say that this chord, C#-E#-G## is indeed an augmented chord. Isn’t that neat? The name of this chord is C# augmented. Let’s do one more to drive the point home:

Wow, I bet some of you all out there never thought about chords in this way. I can admit when I was first taught this technique of looking at chords, I was in awe. Next comes the chords built off D.
NOTE: There is a fifth 3-note chord built on C, but in order to understand it you have to look at the major scale. I’m not using the major scale here, just notes.
