Hi Pedja
Back from my trip and just about over the jet lag.
Getting stuck into the tw theory lessons now. And enjoying learning this stuff but its a steep learning curve for me every phrase s new and one leads to more!!
Major scale was new to me but I understand the formula for it, ie
T T S T T T S
So in C it becomes C D E F G A B C ie no sharps or flats
In F it becones F G A Bb C D E F
And in G it ecomes G A B C D E F# G
I am beginning to work out the triads ie C is made up of C E G, will complete this post wheh I work out the rest and also do the 4 part harmony.
Looking ahead at the idea of cadences which I have found out is a sequence of chords or a progression this is where I am having trouble finding out which chords are minor/major.diminished and more importantly why??
Can you help with this section?
Thanks
Hi Tony!
Welcome back from your trip
I hope you had a good time and are ready to tackle workload here at GMC.
Regarding construction of major scale(s) you got the right idea. Formula is correct and so are the notes for each of the 3 scales. Your question was directed towards modes and chords progressions. I will try to help you as much as I can, but I strongly advise you re-read the links again it might come to you after doing so.
Here we go - what are modes? Modes are scales by themselves. They come or better yet occur within specific original scale. Right now we are working on Major scale. In Major scale we have 7 different letter names and 8th letter name is the same as first. That is a definition of a major scale (7 different notes and 8th that repeats the first one). What are modes? Well if we start a major scale on any of those 7 different notes and end the scale on that same note octave higher or lower, we now have a MODE! So in key of C major we got 7 different modes. C something, D something, E something etc you get the idea. Now if you read the links again, you will see that I listed chord progressions for each mode in C major scale!
C IONIAN = C D E F G A B C
This mode is also known as C major scale. We already learned the order of chords that appear in that mode and the type.
The beauty of other modes is that we keep the same chords that are already in C major scale, but only difference is now they appear on different place in scale. Let me give you an example. In C major, C major chord is known as I but in D DORIAN mode, C major chord is bVII! In A AEOLIAN C major chord is bIII! You see how this works? Same chord, on different scale degree. Why? Because we treat each mode as a scale itself and our order of whole steps and half steps changes as well as the way we label scale degrees.
Now to answer your questions about chords, we have 3 part chords, which you did, they are known as TRIADS and have some sort of 135. We built Triads by stacking diatonic 3rds one on top of another. So C major scale has C D E F G A B C notes. If we start on C note and want a chord, we would skip D note, get E, skip F and get G. So we now got CEG, which is also known as C major triad. If we stack another 3rd we would skip A and get B so we get C E G B which is C maj7!
Why is this?
Because each chord has its own formula. How do we know or figure out those formulas? By using intervals! Intervals are very important in music as they describe distance between any two notes in music.
Here are the formulas for Major, Minor Augmented and Diminished triads!
Major triad = Root , major 3rd and perfect 5th (this is all in relationship with Root of the chord)
Minor triad, Root, minor 3rd and perfect 5th
Augmented triad = Root, major 3rd and augmented 5th
Diminished triad = Root, minor 3rd and diminished 5th
Do you need the distances for intervals? If you do, check out my interval series where I covered all the intervals from unison up until octave!!!
Here is a thread where you will find all those lessons.
