Per Dahlqvist: Carl Orff Competition 2019 Zuruckhaltendt

The piece is largely modal; sets of tones (or rather pitch classes) are derived from
the Mozart and Orff quotes respectively. The piece is propelled by the tension between the
Mozart "set" and the Orff "set". Still, the Mozart quote is there, most of the time,
but sometimes permuted, sometimes stuttered in a catatonic fashion.
The piece starts with a slow morphing from the Orff chord to a cluster containing all
notes in the Mozart set, slowly guided by his melody.
The are also more modes/sets derived from the others. Of some importance is the complement of the
Mozart set, often used for accompanying purposes.
