To begin_Lets make this simple,so everybody interested in music theory can understand mode scales and how mode scales are constructed.
There are 7 mode scales for each key in music. Lets start off by looking at the C major scale in diagram # 1.
Diagram # 1 shows the notes for the C Major scale in the key of C Major. Notice the numeral on top of each note. The number represents the position each note holds in the scale.
Each mode scale starts out with it's root note being one of these notes in the C Major scale, and runs the full tonal scale of 7 notes to the octave root note.
By looking at the mode key chart below,for the key of C major the C note is the rootnote for the Ionian Mode the D note is the rootnote for the Dorian Mode the E note is the rootnote for the Phrygian Mode the F note is the rootnote for the Lydian Mode the G note is the rootnote for the Mixolydian Mode the A note is the rootnote for the Aeolian Mode and the B note is the rootnote for the Locrian Mode
The examples for mode scales above were givin in the key of C Major This same example can be done in any of the Major Keys in music. The only difference would be the notes used for the givin key. The modes stay true for each key,for instance the rootnote for the Ionian mode is always the rootnote of the keys major scale, the rootnote for the Dorian mode is always the 2nd note in the keys major scale and so forth.
Mode scales are constructed by a technique using interval steps on the chromatic scale. An interval step is the distance from one note to another. There is 2 types of interval steps. The halfstep, by looking at diagram No. 1 is the distance from A to A#, which is 1 note distance apart. The wholestep is the distance from A to B, which is 2 notes distance apart.
Diagram # 1
Being there is 7 different mode scales, each mode has it's own unique interval step pattern that makes up the notes for that particular scale.
Below are the Interval Step Patterns for each of the 7 modes. If in need of instructions on how to use the charts, see the example below.

The chart on the right has the Chromatic Scale with notes arranged in a circular pattern. I call this chart the Scale Cycle. This is the chart the Interval Steps will be performed on , to find the notes that make up the different scales in music.
Take notice of the five notes in the inner cycle. These notes are flat notes, and they have the same tone as the notes they share the space with. Depending on the Key your in, and the scale your finding the notes for, will determine which note will be used.
Moving around the cycle finding the notes for a scale, is basically pretty simple. But like everything else, theres a couple rules to follow, in order to make sure you come up with the right notes for that scale.
Rule No. 1, always move around the cycle in a clockwise direction.
Rule No. 2, the first note you start out with, is the name of the scale. An example being the { A - Major } scale. You would start out on the cycle with the { A } note.
Rule No. 3, when your taking an interval step, Don't start your count from the note your on. Always count your steps from the next note, that is in the clockwise direction.
Rule No. 4, every interval step you take, is a note that you arrive on, and will be a note in the scale.
Alright, now that we have the rules covered, will begin an example on finding the notes for the Dorian Mode Scale in A" The following is the Interval Step Pattern for the Dorian Mode.
Root | w/step | h/step | w/step | w/step | w/step | h/step
On the Scale Cycle we will begin on the { A } note. This is the 1st note in the scale, also known as the Rootnote.
The 1st Interval is a { wholestep } which takes us to the note { B }. Now our next Interval Step, which is a { halfstep } is taken from the B note, and that takes us to the { C} note.
From the C note, we take the next Interval which is a { wholestep} and we arrive on the { D } note.
From the D note, we take the next Interval which is a { wholestep } and we arrive on the { E } note.
From the E note, we take the next Interval which is a { wholestep }and we arrive on the { F sharp } note.
From the F sharp note, we take the next Interval which is a { halfstep }and we arrive on the { G } note.
So, here we have it, the notes that make up the { Dorian Mode in A } are
A - B - C - D - E - F sharp - G.
On the Interval charts above , I added the next step to bring you to the Octave of that scale. Which is the same note you started out with, except an Octave tone higher.
