Let A be a finitary hereditary abelian category and D (A) be its reduced Drinfeld double Hall algebra. By giving explicit formulas in D (A) for left and right mutations, we show that the subalgebras of D (A) generated by exceptional sequences are invariant under mutation equivalences. As an application, we obtain that if A is the category of finite dimensional modules over a finite dimensional hereditary algebra, or the category of coherent sheaves on a weighted projective line, the double composition algebra of A is generated by any complete exceptional sequence. Moreover, for the Lie algebra case, we also have paralleled results.
