The little pieces are as delightful as their evocative titles, such as "Die schüchterne Sekunde" (The Shy Second), "Die faule Terz" (The Lazy Third), "Sextenblues" (Sixth Blues) and "Wo will die Septime hin?" (Where is the Seventh Going?). But there is much more: Sigrid Naumann's accompanying texts encourage players to treat the notated material freely, to vary it, to improvise upon it and to contribute original compositional ideas.
