Those are all just modes of the major diatonic scale. I cover modes in depth in these tutorials.

But yes, they all have different sounds because they have different interval formulas! Fun stuff!

Yes, you can apply triadic chord harmony to any diatonic scale. I cover that in the tutorials linked above. It might help to get clear on how that works for standard scales as well as altered scales. I cover that in these tutorials.

The sound of any given scale or modes is determined by its unique interval formula. So, get used to the sound of each scale or mode. Then you decide which scale or mode to use in any song by whether or not it's sound works for your purpose in that song or piece of music.

In short, your question is like asking, "Can I use any tool for any job?" The answer is, "You need to pick the right tool for the specific job you are doing." Make sense?

[quote=Philip Charles]Q 3. Do each scales generate different mode for the song??

Each scale generates its own modes. But you have to decide by the sound & the harmony if it works for the song you are playing.

Q 4. Do each of these scales used specifically to express feel/mode of music or can be used normally in any circumstances

Each scale or modes has it's own unique interval formula that creates it's own unique sound. Assigning a specific emotion or feeling to each mode is up to each individual musician as they learn, practice & experiment with them.

Hope this helps!
