In the cadenzas Beethoven wrote for his C-Major Piano Concerto, opus 15, higher high-notes are utilized than those in the concerto itself. The cadenzas were written down around 1809, more than a decade after the concerto.

Architectural juxtapositions that result from additions are part of our understanding of buildings used and remodeled over time.

Piano-making developed in the years between the first performances of Beethoven’s C-Major Concerto and the notated cadenzas. Later keyboards included higher notes. For the performer, aesthetic questions arise.

I can’t say for certain why Beethoven notated these cadenzas. For his own use? Doubtful. He would have elaborated, embellished, ornamented further, or anew in a performance. Did he write them down for an amateur to play? Some believe they’re for Archduke Rudolf. Beethoven’s reason for writing these cadenzas is less obvious — than in the case of cadenzas op.  15, andere KadenzMozart sent to his sister, or wrote for students who gave public performances. Beethoven’s written cadenzas are a recording of his improvising. Not a sound recording, but a recording no less. Perhaps these pages are just to help in remembering good ideas? (Perhaps that is the reason all written-music is written?)

Within the C-Major Concerto, I like to avoid playing notes above the high F (now signified F6) that was the normal upper-endpoint of Viennese keyboards in the late 18th century. As a kid, learning the concerto from Franz Kullak’s edition, I read a high F-sharp in the concerto’s second theme, a half-step higher than that high endpoint F:

Surely Beethoven would have preferred this leading-tone F-sharp if it was available, an editor might have reasoned? (The composer certainly wrote the F-natural though.) In the second appearance of this passage, in C Major, and in a slightly lower register, we do find the raised leading-tone B-natural.

Many pianists and conductors endorse the F-sharp, this rereading/modernization/modification/improvement. Let’s notice some of the details of the orchestration in the C-Major and G-Major presentations of this music.

In the G-Major version as it was written, the piano does not have raised leading-tone F-sharp, and the music played by the strings avoids the issue — no discrepancies, no questions.

In the C-Major version, the orchestra’s music is quite different. Along with the piano’s leading-tone B-natural, there are sustained lines for cellos, violas, and first violins. The second violins have a repeated C. This is in considerable contrast to the open, more neutral texture of the G-Major statement of the theme.

If a pianist decides to play the high F-sharp in the first statement of this theme, shall we also rewrite the concerto’s string parts? As it is written, these changes provide subtle development/evolution of the material.

Within the text of the cadenzas to the First Concerto, awareness or even mocking of the register expansion/change/mismatch may be discerned. Starting from the customary, humdrum high-F, this scale makes a cheeky ascent:
