The aim of this paper is to study some brackets defined on$(\tau,\sigma)$-derivations satisfying quasi-Lie identities. Moreover, weprovide examples of $(p,q)$-deformations of Witt and Virasoro algebras as wellas $\mathfrak{sl}(2)$ algebra. These constructions generalize the resultsobtained by Hartwig, Larsson and Silvestrov on $\sigma$-derivations, arising inconnection with discretizations and deformations of algebras of vector fields.
