Now that you know where the ionian mode comes from and how to find it, we can go on and learn about
the rest of the modes. There are seven of them all together, one mode for each of the seven notes
in ionian. Their names must be memorized in the proper order.
The seven modes are :
1. Ionian
2. Dorian
3. Phrygian
4. Lydian
5. Mixolydian
6. Aeolian
7. Locrian
All seven modes are actually right inside of Ionian because after all, they are only different
modes of that one scale. We will learn about the six other modes together by comparing them to
Ionian.
I have already mentioned that the other six modes are right there inside Ionian, so you may
be wondering where. We have already learned that the "doe, re, mi, fa, so, la, ti, doe" thing you
learned in grade school was the ionian mode. In this scale using our fictional key of "DOE",
the root note or key would be "DOE". So we could call this "DOE Ionian", as it would be the
Ionian scale in the key of "DOE".
"Doe Ionian"
Doe, Re, Mi, Fa, So, La, Ti, Doe
As long as this scale is in the key of "doe" it will be ionian (or the major scale). This is because
we know the intervals between these notes are W,W,H,W,W,W,H. And anytime we use those intervals
in that order we will get the ionian mode, regardless of what key we are in (even if its a made
up key like this one).
But what happens if we use all the same notes but start with the "Re" note and end with the next
"Re" note ?
Now our scale would be :
re, mi, fa, so, la, ti, do, re
This would be a completely different scale and we would call it
"Re Dorian".
Now you may be asking yourself "if we are using all the same notes as before, why isn't
it "re ionian" ?". I will answer that question. Lets think about the intervals that it took
to get the sound of the Ionian scale. If the notes are all still the same, then so are their
intervals of W,W,H,W,W,W,H. The only problem is that if we are starting on the second note, the
intervals are now W,H,W,W,W,H,W.
By starting at the second note we are changing the key of our
scale to "Re", and the intervals between the notes will be different. If the intervals are
different it will no longer sound like the major scale because it isn't.
It is now "Re Dorian". Remember, music notes just go around and around repeating themselves
every octave. What makes different scales sound different is their intervals, the space
between the notes.
So if we start and stop playing at a different place, the intervals between the notes are
now different, and thus we have a different scale. This will become clearer and be more
thoroughly explained in coming lessons.
So the 7 modes of this scale would be :
"Do" Ionian
"Re" Dorian
"Mi" Phrygian
"Fa" Lydian
"So" Mixolydian
"La" Aeolian
"Ti" Locrian
