Keep the old, but be generous with new. Fundamentally the editor of the New Sonatina Book has followed this principle. Therefore in the book are found sonatas for children which are almost "classical", as well as other works which have long been used successfully in teaching the Piano but which are not found in previous collections such as, for example, the Vienna Sonatinas of Mozart which acquired fame so quickly in the new Schott edition, the charming Spring Sonatina by Handrock, some melodious compositions of Theodor Kirchner, and as a contemporary work Gretchaninoff's Sonatina which has proved itself as a splendid display pieces for pupils' concerts.
