When notes of a chord are placed larger than an octave it is said to be in open position.

Motive or Motif is a short melodic, rhythmic, or harmonic element that is used repeatedly. A short tune that characterizes and unifies a piece of music.

In 1st inversion triad, move the root or bottom note to the top of the triad making the 3rd the bottom note.

In 2nd inversion triad, move the root note to the top, then add the 3rd on top of that making the 5th the bottom note.

In V7 1st inversion, move the root note to the top making the 3rd the bottom note.

In V7 2nd inversion, move the root note to the top, then add the 3rd on top of that making the 5th the bottom note.

In V7 chord 3rd inversion, move the root to the top, add the 3rd, and then the 5th on top of that making the 7th the bottom note.

Ionian (I) - major scale
Dorian (ii) - minor scale with a raised 6th
Phrygian(iii)- minor scale with a lowered 2nd
Lydian (IV) - major scale with a raised 4th - brightest mode
Mixolydian(V) - major scale with a lowered 7th
Aeolian (vi) - natural minor scale
Locrian (VII) - major scale with a raised 2nd and 5th - darkest mode

A typical blues progression would be:
I, IV, I, V or V7, IV, I

To change a major scale to a blues scale: 1) Remove the 2nd and 6th scale degrees. 2) Lower the 3rd and 7th degree. 3) Add a flatted 5th.
