Earlier posts look at how to form and play different permutations (or "modes") of a key.
These principles apply to any key, including the key of B, as we'll explore here. When you take the 7 notes of the B major scale -- B, C#, D#, E, F#, G#, A#, B -- you create 7 modes starting on each respective note.
Each pattern is a distinct sound because each mode begins and ends on a different note (or "tonic"). In this example, the tonic of B Ionian is B ... while the tonic of C# Dorian is C# ... and so on.
Each sequence of notes sounds nice. But they sound especially good when played as chords -- like these chords of B Ionian (a.k.a., B major):The B Ionian mode sounds good fleshed out as harmonies because it's really just the major scale pattern. And just like the notes, these same 7 chords can also be arranged into 7 permutations -- like these three patterns, for example:
And the same idea applies to all of the other chords in this key, as you can see here....
