If you can find the C-below-middle-C ?
Put your small finger on C,
your next finger on the next white key: D,
your middle finger on the next white key: E
your index finger on the next white key: F
your thumb on the next white key: G
Lift your fingers away from D and F -- to keep this simple -- all we did was identify the D and E and F and G keys, relative to the C key.
Press C and E and G (small, middle, thumb)
to play a "major" chord in C.
Move your fingers "up":
C to D, E to F-sharp, G to A,
and play a "major" chord in D.
Move your fingers "up":
D to D-sharp, F-sharp to G, and A to A-sharp,
and play the chord in D-sharp (usually called 'E-flat').
Move your fingers "up":
D-sharp to F, G to A, and A-sharp to C,
and play the chord in F.
Move your fingers "up",
F to G, A to B, and C to D,
and play the chord in G.
Go back to the starting position (C-E-G),
and move "down": C to B-flat, E to D, and G to F,
and play the chord in B-flat.
So far, you have C-major, D-major, E-flat-major, F-major, G-major, and B-flat-major.
There are more chords, but most pop-music is in one of these keys.
Give it a try.
A lot of left-hand stuff is just the small-finger and thumb, omitting the middle finger, e.g., C&G,
to avoid a too "muddy" sound.
Or, "stretch" your hand: C-and-G-and-the-next-higher-C.
It is not active, it is on "normal"
