In what turned out to be his last composition, Beethoven wrote the words "Must it be? It must be!"" on the manuscript of his Opus 135 String Quartet number 16.
His title for the entire last movement of the piece was "A difficult decision".
After a lifetime of groundbreaking music, Beethoven returned to the string quartet for his final explorations. He had always been an admirer of Haydn, the forefather of string quartet composition, and of Mozart, the genius of all forms.
A string quartet in some sense is a musical conversation between four instruments, classically described in four movements. The words Beethoven inscribed on his last quartet attest to the fact that for him, creativity itself was also a kind of conversation the artist has with oneself.
By turning the conversation into a question and an answer, Beethoven gets to the heart of the true creative impulse: what is the question, and what might the answer be?
In this sense, gleaning the question that underlies creative work allows one to always be actively searching for an answer.
How blessed we are when we come to know the question!
