With Melodic Practice Pieces op. 149, Monika Twelsiek, professor of piano pedagogy and author, presents Anton Diabelli's lively practice pieces for four hands, which every piano student should have dealt with at least once. The aim of the exercises is to teach the most common keys by means of the quintuple and thus to gently introduce the basic notes c, g, f, d, a, e to major and minor. The book follows a well thought-out teaching concept, because the compositions are arranged according to a slightly increasing degree of difficulty. Both hands are mostly played in parallel.
