P is for poetry, because there is no song without poetry. For us, literally, prima le parole, poi la musica, a poem that inspires the composer is needed to have a Lied. So, poetry couldn't be left out of Liederabend's alphabet. But how do poets arrive at those poems? Reading, of course (thank you, Captain Obvious!). But do they read to find some poems that can be musicalized? Or maybe do they read for pleasure and then a poem asks them for music?
We know that Wolf was an incurable reader of poetry and marked in his book the poems that would become music. Schumann was also a passionate about reading (he even hesitated between being a writer or a composer) and he was organized enough to write down when and where he had found that poem he had composed.
