In this article we introduce an improved version of CAT (Cataldo Advanced Transformations). The purpose of CAT fundamentally lies in providing musicians with a reliable instrument that may effectively assist them in carrying out chord progressions analysis. The correct application of CAT allows to convert any harmonic progression, net of some very rare exceptions, into a mere sequence of plagal and perfect cadences. Amongst other features, the improved version of CAT, unlike the previous one, takes also into account Modal Interchange and Tonicization.
