Johann Kreuser, Homerische Rhapsoden oder Rederiker der Alten

Kreuser surveys poetic improvisation throughout modern Europe, in Arabic cultures and in the ancient world, naming (in an endnote) several German improvisers who have been reviewed in recent periodicals. He considers improvised poetry and music a pleasant entertainment for the masses, a momentary pleasure that cannot measure up to Homer or to the productions of poets and orators when language and culture are in a more mature state.

O. L. B. Wolff, Portraits und Genrebilder: Erinnerungen und Lebens-Studien

In this autobiographical introduction, Wolff relates how he invented improvisation in German, undertaking a quest to obtain advice and evaluations of whether his talent is or is not genuine. Wolff doesn't trust the judgement of journalists and critics, which he believes derives from their jealousy of him. Instead, he will listen to the opinions of admiring audiences and true artists, above all Goethe. Goethe finally gives him the advice he was seeking — which also leads, however, to the end of Wolff's brief career as a touring improviser when Goethe critiques his improvisations as too sentimental and subjective.
