Let \(H\) be a commutative coassociative Hopf algebra over a field \(\mathbb{K}\) and \(R\) be the cobar construction on \(H\). Given any left DG-module \(M\) over the DG-algebra \(R\), the author constructs a new Massey product on \(M\). He also proves some basic properties of this Massey product.
