Ich bin bereit! WoO 201 (Part One)
This musical joke comes from a letter addressed to Vincenz Hauschka. Hauschka, on behalf of the Society of Musical Friends of Austria, had asked Beethoven to write an heroic oratorio for the Society. Beethoven, in high humor, responded as follows:
Best and Chief Member of the Society of Musical Fiends [sic] of the Austrian Imperial State!
[Translation by Dr. A.C. Kalischer, Beethoven's Letters, (Dover, 1972) p.253.]
However, the oratorio in question, The Victory of the Cross, was never written. The libretto, by Joseph Karl Bernard, was not supplied to Beethoven until October 1823, and then was found to be so unsatisfactory that Beethoven never began serious work on the project.
Ludwig Misch , discussing Beethoven's Riddle Canons, writes about WoO 201 : "The motifs given in a letter to Hauschka in 1818 also permits canonic imitation, the first [Ex.1] (which Beethoven follows immiately with the comes ['Tenor'] and to which he later [Ex.3] adds a counterpoint) at the unison at the distance of one bar. The second [Ex.2] at the fifth below at the distance of one bar, possibly also on the fourth above at the distance of half a bar. But naturally these are not really fragments of canons but conceits evolved from Beethoven's contrapuntal thinking."
Misch' reproduction of Beethoven's first motif [our Ex.1] contains an error : it has an additional barline after the first two beats, giving the impression as if the music is in 2/4 metre. This makes Misch' proposal for canonic imitation (entry at the distance of one bar, ie., 2 beats) appear nonsensical; viewed against the correct note text (entry at a distance of 4 beats) his suggestion works fine (ignoring Beethoven's 'comes'). This is rather ironic.
