For an algebra with bracket and two two-sided ideals, several subalgebras of the Lie algebra of derivations of an algebra with bracket are introduced and characterized. The interplay of these subalgebras with central derivations and inner derivations of tautological algebras with bracket is analyzed. Exact sequences of Wells-type are obtained, which include the various types of subalgebras of introduced derivations, and which are associated with an abelian extension of algebras with bracket.
