1.19Your first harmonic experiment

At the piano, play:

C

then:

G7

then:

C

Notes:

C:

C E G

G7:

G B D F

C:

C E G

Now don't think:

C chord, G chord with an extra note, C chord.

Think:

home → tension → home

That's harmonic function.

We'll study it properly later, but I want your ear noticing it immediately.
