The Belgian composer Nicholas Lens presents extremely varied etudes, exercises and simple phrases with wonderfully telling titles from poetry and everyday world for children and adults. For the most part the studies are tonal and simple and have no constructed line. They are not based on any educational concept but leave the musical dramatization to the pupils and teachers: 'Notes and rhythms are just notes and rhythms, they do not have that many rules, they do not have any pretension, they are just tools for you to use to express what you want to share'.
