One of the things you may be called upon to do as a bard, is to create a performance space. There’s no way of doing this that is right, it’s a case of considering the space, and the intention and nature of the gathering.
If you use a performer/audience model with the audience in rows and the performer(s) at the front, then you elevate the status of the performer and encourage the audience to be an audience. It can take longer to get performers on and off, and if there is more than one performer then someone must act as master of ceremonies and handle the changes. In some venues, this layout raises issues of who can see and hear – a stage is often essential, amplification may be necessary. If there are a lot of people, this is often the best layout to use.
Working in the round puts everyone on an equal footing, there is no ‘front’ and everyone is able to interact, so there’s much less divide between audience and performer. If most of the audience are also performing, this can be preferable, and quicker. It does create a more casual atmosphere, and does not give the same status lift to performers. It can make the space slightly harder to control. In a circle of under thirty people, this layout is viable, but if it gets to be a larger crowd, you may have to have inner and outer circles, which will cost you some of the inherent democracy.
When you’re running a space, it’s good to test the acoustics of it and find out if there are any sweet spots for getting your voice to carry, or any dead spot to avoid using altogether, or encourage the accordion players into! They don’t need any help to be heard.
Never try and run an event from a position of having your back to the door. Make sure you can see the majority of movement in the room. If you’re outside, try and find something to have at your back – a tree for example – so that people can’t creep up on you. To hold a space you need to know what’s going on in it.
