These duets, composed in 1855 are intended to help students to progress - technically and especially musically in carefully designed stages. Starting with the octave g'-g'', students acquire a solid musical foundation before progressing to a wide range of pieces in different styles and characters which in turn provide them with the motivation for further study.
