Welche Instrumente muss ich spielen, um professionell komponieren zu können?

What instruments do I need to play to be able to compose professionally?

The choice of instruments when working as a composer is entirely up to you, although it is an advantage to be able to play the piano and master a few other musical instruments very well. However, whether this is violin or double bass, trumpet, clarinet, drums, guitar, saxophone, harp or ukulele is ultimately not decisive for starting a career as a composer.
