How do I begin to code a line where if key f makes a sound?

This is my current code on where if key f

game.Players.LocalPlayer:GetMouse().KeyDown:connect(function(key)
    if string.lower(key) ==  "f" then
        --this is where I am supposed to write the sound code but don't know how to start it
    end
end)

I am asking how to start that line of code not requesting for you to do the whole script so please don't this down admins.
