In the summer of 2015 Hans was invited for the second time to give masterclasses in improvisation at the LatvianClassicalMusicFestival in Madona, Latvia. During this week Hans coached, instructed and guided a group of 50 young musicians who had no experience in improvisation. After three days these children that at first appeared shy were now running around on stage including theatrical effects in their improvisation performances.
From June until July 2015 Hans was invited as guest conductor, lecturer, instructor and solist to Ecuador. Hans gave masterclasses and individual lessons about brass playing, musical interpretation and ensemble playing. In addition he conducted and performed as solist with several orchestras and ensembles.
Together with the NaturalTrumpetEnsemble of the Hague a concert series for children was performed in Bremen in April 2015. The concert series “Macht und Musik” was an educational project to teach children about early music and the development of it.
