Imagine your middle-management team sitting down together to play “Knocking On Heaven’s Door”, with your CEO on drums and other members of your team on bass, guitars, keyboards and singing. That’s kind of how it works. Everyone gets a crash course in all the band instruments first, and then the whole team gets taught to play a song together. It’s all about listening and working together, recognising roles, understanding the importance of everyone’s contribution and much more. No previous musical experience is needed (and if some people have it already, they will be put on an instrument that they don’t play so everyone is in a similar position).
