Personally, I think it is. There is room for incorporating both into the poetical sphere.
In today's world poets write to perform, but can these poems transfer themselves onto the page? Yes.
Poetry started out spoken - performed on the streets, in theatres and to anyone that would listen. The likes of Chaucer and his 'Canterbury Tales' or the many plays and sonnets of William Shakespeare, were first told - spoken in amphitheatres and whispered among friends.
We have become disillusioned, only concerned with how others will criticise our work and therefore pass judgement on us that we have forgotten that actually it's quite natural to speak our thoughts.
Within our laws today we are lucky enough to have 'freedom of speech', meaning we can say what we want without fear of prosecution. We are lucky.
Gabriella DePinho explores this notion very accurately in her poem 'do not silence the written word' shown below:
When poets write to perform, they are writing for a different audience. An audience that "may love your work, but at the end of the night, they have nothing to take home with them: no book, no tangible product to which they can refer later if they want to revisit the poetry." Described by Katie Ailes.
Essentially, what this shows us is that careful consideration needs to be undertaken on the creation and purpose of an artiste's poetry and therefore, the audience it is targeted at.
Written poetry needs to have rhythm, but it is not a necessity, whereas a performance piece relies heavily on its rhythm. This will therefore determine the type of devices used within the piece.
Carefully consider how you construct your verse by considering how you want it to be heard. That way you'll write for the right audience.
