Haiku is meant to be read not heard. That is the conclusion I came up after hearing poets read out their own poems. Unlike longer poetry, the brevity of haiku does not allow for buildup or setup of emotions when read aloud. Reading it allows me the leisure of pausing, contemplating and digesting the verse. In contrast, listening to the poets doesn't allow me to capture the emotions in their poems. I would love to hear other poet's views. Thanks.
P.S. You can listen to these readings at 'The Living haiku anthology' website.
