music before content

A poet's attunement to the activity of his speech organs can trigger corresponding aural (phonic) 'ideas', in which case a poem's sound structure is tied to the poet's phonic imagination, and the sequence of speech organ movements or sequence of phonic imaginings marks the inception of poetic thinking. That's what poets mean when they say that poetry begins with sound. Schiller, for instance, would often hear "a poem's music in [his] soul first, before having a clear idea of its content" (cited in Ernest Dupré and Marcel Nathan, le langage musical: Étude medico-psychologique, 1911)
