What is a pile of nonsense ? It ' s a fairly lengthy article . If it is so fallacious and wrong it should be easy to point out what is incorrect . <| sep |> I ' m just grateful I taught myself from the beginning way before computers , let alone the internet including learning songs by ear because I couldn ' t find the notation , and joining a band really early on .
