Summary: Itt was a treat to sit down with Vassilis Papavassiliou over a coffee at the 2018 European Bass Congress and discuss his current topic of research: vibrato. Vassilis has presented a session on vibrato at past bass conventions, and I learned a lot chatting with him about the topic. He also has an outstanding online resource on vibrato which s a must-read for any bass player, with great video examples and detailed description about the mechanics and aesthetics of vibrato.
