In some ways of thinking, the actual key of a song becomes irrelevant.  Either because you may want to play it slightly higher or lower, or if you simply want to analyze the relationships between chords.  So, writing a chord progression in roman numberals makes it easier to discuss relationships.
 
An uppercase is major, a lowercase is minor.  If you're in the key of C playing a I - IV - V progression, the chords will be C, F, G.  If it's i - iv - VI - V, then it's Cm - Fm - A - G.  The numbers are based on degrees of the major scale, so even if you're in the key of Cm (which the minor 3rd is an Eb), a i-III-v progression would be Cm E G, not Cm Eb G.  If you wanted to represent Eb, you would represent it as bIII.  When me and a friend are writing riffs, we usually discuss it this way, i.e. "Should we go to the minor third before or after going to the flat 5th?"
 
Using the notes in a major key, the natural major/minor relationships are as follows: I IV and V are major, ii iii and vi are minor and vii is minor-diminished (1, b3, b5).
 
Louie Louie and TONS of other 50's and 60's rock and R&B songs, and standard 12-bar blues utilize some version of the I IV V progression.

Id watched this video of Joe Satriani on YouTube talking about modes and I thought that a mode was basically just another scale. He was playing Lydian, Dorian, Locrian etc... but always staying in the key of E.

Here it is: http://uk.youtube.com/watch?v=LWHKeC4IEgA

So I learnt "E Lydian".  But I read on the previous page that Lydian can only be F? Ermm

/really confused. :P
No, you can transpose the Lydian mode into any key you like. in my example I showed how the lydian is made from all the white keys played from F to F on a piano keyboard,
 
if you transpose that down to E you get: E, F#, G#, A#, B, C#, D#, E
 
(or all the same notes as B Major, which makes sense as F Lydian is all the notes from C Major)


So Lydian is 3 Whole Steps - 1 Half - 2 Whole and then 1 more half step?

and if you move that from E to D Lydian it becomes - D, E, F#, G#, A, B, C#, D?


What combination of intervals (I think it's called that) make up the Dorian mode?

A few observations about scales non based on major scales: I know we can use, for example,  a whole tone scale, it contains 6 tones and only 1 mode (itself).

We can use mode for more exotic scales or for pentatonic and blues scale.

But what if some of these modes doesn't contain a third at all, how we will define a character. It's not a problem for my if I'm playing it, but  I'm curios what the musical theory have to say.

For example, two Japanese scales (Hirajoshi and I forgot the name of the second) are basicaly just a two modes of a same scale:

A H C E F A
H C E F A H
They're both lovely.

Of course you can continue with modes...

(H tone here is what English-speakers are calling B, in some European countries H is B, and B is Bb)

Bumping...

Someone mentioned the melodic minor scale.  The James Bond 007 theme is based on that scale (or maybe it's harmonic minor).  The very distinctive chord you hear is a minor chord with a major 7 on top.  (I believe it's Em/maj7.)  Pretty wicked.  Purely harmonic minor gives a really old fashioned medival feel (Greensleeves or the Christmas carol What Child is This?)
 
If you consider the melodic minor as a static scale (i.e. not using it only when ascending or what not) then you can draw 6 other modes from it.  (The anti-modes or whatever you want to call them.)  These are the only other 7 note modes that you can come up with without having a gap of more than a whole step between notes.  But aside from discussion's sake, they're probably largely useless Tongue.
 
You can really get a good wicked effect if you play a diminished chord arpeggio (1, b3, b5, 6th).  The diminished chord repeats every minor 3rd, so if you move it up a minor 3rd, you're playing the same notes, just a different inversion.  Whole tone has some similar concepts, but is generally more disorienting or dreamy than wicked.
 
The major #9 is a pretty funky chord (it's basically a major chord with a minor 3rd an octave higher).
Adding a 9th will make a minor chord sound even sadder, and a major chord sound even happier.  Replacing a 3rd with a 9th makes you sound like Andy Summers.
Moving the bass note of a chord up a whole step will basically turn it into some crazy extensioned chord (like an 11th or 13th depending on what you're playing on top).  I find it's a lot easier to visualize than actually picking out the extensions (on piano at least).  Steely Dan would use these types of chords all the time.  Steely Dan definitely exercises your chord vocabulary.
 
But in the end (IMO), a skilled songwriter can make better use of 2 basic chords than someone unskilled trying to throw all this other stuff in.

Oops...Embarrassed   I certainly can't argue with the redundancy of the church modes now, or the six rhythmic modes for that matter!  I'd love to get some early-music jams going (that adhere to all those modes), but time and circumstances haven't allowed... 

 
the modern day modes are my musical bible. I think the church modes are just limited versions of what we have now. For the sake of medieval music though, I'd stick to a church mode in an instant!

The medieval modes (Church modes) were similar to our current modal system.  Originally there were eight Church modes broken into pairs of authentic and plagal (hypo-) modes: Dorian, Hypodorian, Phrygian, Hypophrygian, Lydian, Hypolydian, Mixolydian, and Hypomixolydian.   A given pairing of authentic and plagal modes would use the same basic note values, but the Ambitus (or range) was different.  An authentic mode would have a roughly one-octave ambitus of tonic to tonic (perhaps including the lower leading tone).  A plagal mode would usually range from a fourth below the tonic to a fifth above the tonic.  During the Renaissance, four new modes were added that conformed (roughly) to the same system: Aeolian, Hypoaeolian, Ionian, and Hypoionian. 

Hope this helps! Smile

If I want to go a fourth below a dorian mode or whatever in a melody, I just do it! I don't need to declare myself as having been in hypodorian. Thanks for to reply though! Post any musical knowledge you wish!

Ok, so is there a scale/mode then that would allow me to write music wiith a european folky(scandinavian in particular) feel to it? I mean, it's easy to write blues melodies on a blues scale, but not knowing it it's a little more difficult because you have to work out yourself what intervals make a melody sound bluesy. Do folky melodies work in a similar way? What about middle eastern folk?I'm attempting to write music influenced by a lot of folk metal that i listen to, but i'm having trouble getting the melodies to sound right.


I haven't been playing much things with celtic or scandinavian flavour, but most of these are just simple melodies. I would use harmonic minor and play some kinda sequences. Just listen to what you play and come out with some catchy melody.

More interesting and more difficult is creating an middle-eastern flavour. I don't find all the scales' stupid names like "eastern bedouin midnight battle scale" much useful. I've come across several names for just one scale so I stopped using those names. But you can create your own scale that sounds arabic. The trick is in the number of semitones (half-steps). The "non-arabic-sounding ones" (all seven modes, melodic minor) have only two semitones, that's too little. You would need at least tree of them, just like harmonic minor. Raising the 4th note of harmonic minor you get a scale with four semitones, which sounds even more exotic. It's refered to as Algerian and Hungarian minor (I call it harmonic minor with raised fourth). It also has, of course, seven modes. My favourite is the fifth (Byzantine scale). Here they are:

1st - T 2M 3m 4+ 5 6m 7M - Algerian scale, Hungarian minor scale
2nd - T 2m 3M 4 5- 6M 7m - Oriental scale
3rd - T 2m 3M 4 5+ 6M 7M
4th - T 2m 3- 4 5- 6m 7-
5th - T 2m 3M 4 5 6m 7M - Byzantine scale
6th - T 2+ 3M 4+ 5 6+ 7M
7th - T 2m 3m 4- 5 6m 7-

Another trick is, over what chord it is played. If you play E byzantine over A minor, it won't sound very exotic, but play it over E major and you got it!

Interesting is Southern Indian classical music with its 72 ragas (scales). But this is just for fun, don't even try to learn it!!

http://www.ipnatlanta.net/camaga/vidyarthi/Carnatic_Basics/Melakarta_Scheme.htm

Chinese music uses well-known pentatonic scale.
There is a mystery (for me) about Japanese music though. I know nothing about its theory, but Marty Friedman of Megadeth knows a lot! So ask him, lol. He has also studied music from all around the world, so can be considered a real expert. Get some of his videos or books, or if you're looking for anything particular, try his website www.martyfriedman.com. He usually has no problem with answering his fans' questions.

In conclusion, it's not only about scales. In fact, maybe, it's not about scales at all. Music is all about intervals - those are the basic building block of music, not the pitches as many people tend to think, but the relationship between them.

why is my thread dying? I was hoping more knowledgeable progheads would share some theory secrets. Step right up ladies and gentlemen! Post something and win a prize!* (*details may apply, like the fact that you don't actually win a prize).
 
C'MON GUYS! Share some knowledge!

***for dargdead*** Why, if I flat the 7th note in minor scale it becomes dorian? Is there another order for the minor scale, modes are differents? Differents positions?

P.s Thx for your help everybody!


I don't know what you mean by "C major dorian" and C minor dorian" ... dorian mode is always minor. Essentially when you play a song in D minor and you're only using white keys, then it's dorian. Wink

You're confused. There is no such thing as "C Major Dorian." C major is one mode, C dorian is another. C dorian contains these notes: C-D-Eb-F-G-A-Bb. In other words, it's a Bb major scale starting from the second note and emphasizing that note as the tonic. So a tune written in C Dorian will fell like it's "In C" but sound different than either C major or C minor.
