Help me get my head around chords in music. I think I understand the basics, but then get confused when thinking about progressions, inversions, root movements etc.
on chords confused me by saying "chord changes have nothing to do with rising or falling pitch.
". But if I see the progression I-IV-V-I in C-Major, I assume I would play ( C+E+G / F+A+C / G+B+D / C+E+G ) which seems like a rising and falling in pitch to me. I think this is where inversions make things tricky. It seems like the root of IV can sometimes be lower that the root of I. Is that correct? What about this whole movement by fourths, thirds, etc.
At a more fundamental level, what is the relationship between chords, instruments and the construction of harmony. Let's take a band with a keyboard, bass guitar, and a lead guitar. How do they construct the harmony. Does the keyboard play its own chord progressions independent of the bass or do they work together to create chords and progressions. My gut tells me that the answer is yes and no.
I have a keyboard so explaining things in those terms will help. Basic discussions on triads, major, minor, diminished, augmented stuff is also welcome.
