We are always delighted to receive applications from outside Germany. However, apart from passing the aptitude test, you must also meet some other criteria before you can start studying for a degree at the Mainz School of Music. These include, amongst other things, possession of the university entrance qualification and knowledge of German.
For more detailed information on the relevant procedures and the necessary documentation, please visit the JGU information website for international applicants. Make an appointment with the staff there and you will get a lot of good advice.
