Contrabass Conversations is a project by double bassist, Jason Heath. It is a weekly 20-30 minute podcast devoted to all aspects of the double bass. Episodes will be released every Monday. In this project, Jason will do interviews with double bassists from all walks of life.
Some of these interviews offer insightful tips to double bass playing and practising, and are worth your time listening to. Even a short five-minutes listening to just one of those tips could have a significant impact in enhancing one's playing of the double bass.
