The series Blockflötentrio Junior with its versatile arrangements and original music compositions from classical to folk to light entertainment, created as an introduction into recorder trio playing.

Each book includes short explanations about the pieces as well as tips for alternative instrumentations allowing tenor and bass recorders to be used. Recorder Trio Junior leads to the trio series Ensemble Dreiklang Berlin, in which all the instruments of the recorder family are combined in various ways.

Apart from the basic instrumentations SSA and SAA the pieces in this book can also be played on the lower recorders (Tenor and Bass). A variety of possible instrumentations are listed in the edition. Each ensemble can therefore choose the instrumentation that best suits it and offers the best sound.
