Why does this brick appear at the side of me?

I'm trying to make a kind of music player thing, but whenever I load my script into Script Builder, the brick just appears at the side of me, instead of in front of me. I tried adjusting the CFrame and Rotation values, but that didn't seem to work. I really want to complete this script, so I hope I will get some helpful answers. Here is the script:

local player = game.Players:WaitForChild('28nard')

local torso = player.Character.Torso

local tab = Instance.new("Part",player.Character.Torso)
tab.Size = Vector3.new(0.1,12,12)
tab.Anchored = true
tab.Transparency = 0.4
tab.CanCollide = true
tab.BrickColor = BrickColor.Black()
local float = coroutine.wrap(function()
    while wait() do
        tab.CFrame = tab.CFrame:lerp(torso.CFrame * CFrame.new(10,7,0),0.7)
    end
end)
float()

Help would really be appreciated! :D
