i need some help with something, obviously. ive seen in alot of discussion some symbols l-V-etc, but i couldnt find anything discussing specifically this. does this have to do with timing or notes or what? or where could i learn more about this?

Hi bobobenbo and welcome to iBreathe!

I suggest you have a look at these articles:

Triads (http://www.ibreathemusic.com/learn/article/56)
This page explains where these symbols (Roman Numerals) are coming from:

And if you need more have a look at 7th Chords (http://www.ibreathemusic.com/learn/article/95)

Hope that helps - if not just post you queries in here.

thanks, that helps a lot. But now I was wondering, is there a certain structure all chords(A, B, C, etc.) go by? Or are they varied?

yes, it's all structured that's why we can use a number system to describe chords and chord progressions independently of the key they are in.

For single notes and intervalic relationships Arabic numbers are used. A major triad translates into 1, 3, 5.

1 being the root note itself
3 being the major third
5 being the perfect fifth.

C major triad: 1 3 5 = c e g
A major triad: 1 3 5 = a c# e

You also should have a look at the Interval article (http://www.ibreathemusic.com/learn/article/31) for full coverage of this topic.

For chords and showing their relationship within a certain key Roman numerals are used.

all chords in C major:

C in the key of C = I
Dm in the key of C = IIm (or ii)
Em = IIIm (or iii)
F = IV
G = V
Am = VIm (or vi)
Bm = VIIm (or vii)

The result of this is that a I - IV - V -I progression in the key of C involves these chords: C - F - G - C

The structure of any major scale and their related chords stay the same - that's why we can transpose any Roman number combination into any other key.

I - IV - V - I in the key of A = A - D - E - A

In order to do this you will need to know your intervals....

I hope that helps.

thank you again. I think I only have one more. take for example, a Amaj chord. the notes are A E A C# E. The triad is A C# E. so does this mean that the notes can be an octave higher (the first A note to the second)? i am assuming that it can, but i guess ill ask. oh yea, how can i tell which A note would be the root of the chord?

Hey Boboenbo, welcome to IBM. What you are referring to are inversions. Theres degrees and other terminology you will learn if you read the triads articles (i recommend you read the intervals article first)The notes can be raised or dropped an octave and still have the same chord (there are some exceptions which you will learn in those articles).

About which note would be the root, i believe you are referring to the same topic so.....yes you guessed it:).....read the articles and thigs will become much clearer.

Im sorry i donīt explain it here for you but a) its a long explanation and b) ive never met anyone who explains it better than Guni.

Hope this helps, take care, and read the articles :)
