If you have not heard about NYCBass blog, you have to.
The NYCBass blog is about “Interviewing and profiling local bass players from the greater new york city area. NYCBass will also provide tips about how to “survive” as a bass player in New York City while maintaining your sanity and not going completely broke.”
The blogger behind is Joseph Wallace, who defines himself as ” …a double and electric bass specialist from the greater new york metropolitan area. He has vast live and studio experience with multiple genres including classical, jazz, rock, pop, r&b, musical theater and more. Joseph possesses a B.A. in Music Education from Montclair State University and has studied with Linda McKnight, Mike Richmond and Bill Moring.”
Well, Bob DiGiacomo was interviewed today in this great blog.
Welcome back to the Musician’s Corner. Previously, we took a look at the C major scale and from it we derived all of the naturally occurring modes. Today we are going to continue to analyze the C scale, but instead, shift our focus to the chords that can be created from it.
More specifically, today we are going to build triads. A triad is exactly what you might guess, a group of three notes. Even though more interesting and cool sounding chords can be built with more notes, doing this would be jumping ahead of our selves. A solid understanding of the triads on which more complex chords are constructed will not only give you a better understanding of the larger structures, but also allow you to take this knowledge into any style you wish. Jazz relies on these larger structures but all western music has these more basic triadic structures in common.
Locrian mode is the last in the series of modes based off of the major scale. This will wrap up our analysis of these seven basic modes, but don’t worry; the conversation gets deeper from here. Using the information from the three relationships we will be able to transfer these modes and scales to different keys. We will also analyze chords and see how each mode matches up to a certain chord. First, let’s take a look at B Locrian.
I know it has been a few days since the last post. Sometimes life gets busy, but I haven’t forgotten about you. Let’s just say that I was giving you time to absorb everything up to this point.
Today’s scale is A Aeolian. This is a very important scale because this is the scale that opens up our parallel universe of minor keys. The Aeolian scale is known as the relative minor or the parent key. But before we open that can of worms let’s take a look at what it is and where it comes from.
A Aeolian Scale:
Derivation from C major:
Now, a look at the three relationships.
Relationship # 1
The formula for Aeolian:
Relationship #2, scale degree and interval from the root:
The chart showing the derivation of intervals between each scale degree:
Relationship #3, relation to root of the key:
The third of a scale determines the basic major or minor sound, but the other degrees also have an influence over that sound. We have seen flatted thirds before in the Dorian and Phrygian scales, but in those cases there was one chord tone that pulled the ear away from feeling it completely as minor. In Dorian, the major 6th gives a hint of a major feeling. In the case of Phrygian the presence of the flat 2nd pulls the ear in another direction entirely. Even though it has the same 3rd, 6th and 7th as Aeolian, that flat 2nd is enough to change the feeling of the scale.
Aeolian has the requisite 3rd, 6th, and 7th degrees plus the major 2nd degree that yields the natural minor sound our ears are accustomed to hearing. In fact Aeolian is also known as the Natural Minor or Pure Minor scale. When it comes time to take a look at how chords structures are created in minor keys the Aeolian scale is going to be our new parent scale. This is the point where your ability to view the scales as entities in and of themselves simultaneously with their relation to the parent key becomes crucial. Once we start analyzing minor chords we will relate them to their parent minor key and their relative major key. Don’t worry, it will become clearer later on.
So you can see why minor concepts can be more confusing that major concepts. There is only one major scale. When someone tells you to play the major scale you know exactly which notes are intended. But when someone asks you to play a minor scale, there are several choices as well as different names that can get confusing. Just Aeolian can be referred to as Aeolian, relative minor, natural minor, or pure minor. On top of that, there are more types of minor scales that we will cover later.
The next post will cover Locrian mode and will wrap up our discussion of the basic modes. After that we will derive the naturally occurring chords in a major key. Once we have accomplished this we will come back to this Aeolian scale and derive the naturally occurring chords in a minor key. So if you only really grasp one mode that you make it this one!
