Leopold Mozart was a composer of a entirely different calibre. His conscious aim was to write simple, undemanding music. In his time ‘the ordinary man’ had started becoming interested in composed music. Since the level of the amateurs was not such that they were able to perform the virtuosic music of the court ensembles, a demand rose for more simple music. Leopold filled this gap. Leopold often used uncommon instruments to give additional colour to his music. An example is Die Bauernhochzeit, which draws on a set of bagpipes. In addition, the musicians have to cheer and clap. Leopold also supplemented many of his scores with simple indications for performance. A typical example of the above is Cassatio ex G 'mit der Kindersinfonie'. The use of simple children’s instruments and toys that made sounds were then in fashion. Although the piece radiates a childlike simplicity, it is not so easy to play. Many of the children’s instruments are only able to produce one or two notes, and for every additional note another instrument was necessary.
