The "will test in music" is available as volitional test for German speaking music students. This test should be provided in different language versions. In a first step, I would like to make an introductory paper available that has been published as German-language article in the Journal "Üben & Musizieren" in 2013. The next steps are to develop different language versions of the test. I'm seeking for international colleagues who want to help me with these steps.
