Pitching the camera up

Im making a gun script, when the player shoots the gun, the camera pitches up a bit.

I have no idea on how to pitch the camera up.

Tried using this piece of code:

camera.CFrame = plr.Character.HumanoidRootPart.CFrame + CFrame.Angles(0.1,0,0)

Though it sets the angle instead of pitching the camera up.
Any help would be appreciated.

Change the Humanoid’s CameraOffset property to shake the camera or move it

Are you looking for recoil patterns?

Here are some pretty good sources. This one answers your question (I believe), as well as this one here too.
