How is präpariertes Klavier played?

Use the instrument only after the required preparation has been installed at the specified strings and positions, commonly with screws, bolts, rubber, felt or other approved materials that modify particular notes. Follow the composer’s preparation table and the venue or technician’s rules exactly; piano model and string geometry can require supervised adjustment. The label names the resulting instrument state, not permission to improvise objects, strike any internal surface or leave the preparation installed after the work.

How does präpariertes Klavier sound?

Percussive, colored, or object-altered piano sound.

In context

Präpariertes Klavier denotes a piano in a specified prepared state. It is distinct from Präparierung, the installation process, and from general inside-piano playing without inserted objects. The Italian instrument abbreviation Pf. prep. expands pianoforte preparato and is not evidence for a German or adjective-only form; no German candidate reached three exact direct expansions, so this headword remains written out.
