You obviously haven't understood mode theory properly mate, no worries I'll try to explain, and for details you can go to Andrew's theory lessons:
1. To write a song it is useful to know the chords you are going to use. This can be very helpful when making a progression. Chords within a key are derived from notes in a scale. For example D major key - D major scale - D E F# G A B C# , you have 7 chords that you can use Dmajor, Eminor, F#minor, Gmajor, Amajor, Bminor, C#diminished chord. For a good example check out my Songwriting Lesson 2. Modes are scales within a key. If we use D major key you have 7 modes within that key. D ionian E dorian F# phrygian G lydian A mixolydian B aeolian C# locrian All these 7 scales are different because they have different whole tone-semitone layout between the notes. Ionian mode is major scale, and aeolian mode is natural minor scale. So for example: if you play Bminor chord in D major key, B minor scale will sound perfect over it, if you play G major chord in D key, G lydian mode will sound perfect over it. if you play G major chord and play G major scale (ionian) over it it will not sound to perfect because you have F note there, and in G lydian you have F#. So you would change the key then to G major key in theory. 3. Let's take your example now and apply the above: We play Dmajor - Amajor chord progression This kind of simple progression allows you to use 2 keys - (1) D major (2) A major. (1) In Dmajor key, D note is the first note, and A note is the fifth note. (D E F# G A B C#) This means that you can use Dmajor scale (ionian) over D major and A mixolydian over Amajor. (2)In Amajor key, D note is the 4th note, and A note is the first note. (A B C# D E F# G#) This means that you can use D lydian mode over D major and A major scale (ionian) over A major. So the answer to your question is YES, you can combine both keys, as long as you keep the progression simple and use chords with tri tones only. If you throw in 7th note and build 7th chords then, it would be obvious what the key is. Hope this helps, if you have more questions, feel free to ask. -------------------- - Ivan's Video Chat Lesson Notes HERE
