1. Welcome to our 7th video in the series on Mozart’s Bassoon Concerto. I am Terry Ewell.

2. Documents from Mozart’s time period and before indicate that many performers improvised their cadenzas, that is, they created the music at the moment. There are performers today who do this as well, and they are to be congratulated for this.
For me, however, the stress of just performing a prepared cadenza is enough. For this reason, ahead of time I carefully craft my composition.

3. Let’s review quickly guidelines about the cadenzas:

1) Style. The cadenza should match the style of the music (harmony, melody, rhythms, expression, technical character)

2) Quotation. The cadenza should make use of materials contained in that movement of the concerto.

3) Brilliant passage work. The cadenza should showcase the performer’s abilities.
To this, you might want to add a fourth guideline.

4) Historically informed. If desired, conform with historical “authenticity.”

4. For instance, you might want to limit the bassoon part to what could be played on an instrument from that time period. This would mean, for instance, limiting the high register range of the instrument to Bb4, the highest note that Mozart wrote in his concerto. Definitely the high F, F5, in Ibert’s cadenza would be ruled out!


5. Examples of cadenzas from the Baroque and Classical periods are shorter in length than those found in the late 1800s and 1900s. For instance, consider this second movement cadenza written by Mozart for the A Major Mozart piano concerto. This cadenza is from a collection of thirty-six cadenzas written by Mozart. I encourage you to study them as you start writing your own cadenzas.


6. In addition, I want to mention an article by composer and oboist John Corina on writing cadenzas. In his article he advocates writing a cadenza by adopting the harmonies created by Mozart in this collection and then using that harmonic framework to create a new cadenza. For instance, he takes the harmonies from Mozart’s cadenza number 15 and then uses them for the Mozart Oboe Concerto.




7. You might find this approach quite helpful. However, I prefer an approach that is less prescribed, which is presented in this and the next video.
 
8. For our purposes here, let’s consider our cadenza in three parts: 1) the opening statement, 2) the middle section which contains at least one sequence and other flourishes, and 3) the conclusion.

9. Instead of just writing the cadenza from the beginning to the end, I suggest that you try writing it from the end first. This might help your creative process. Let’s first consider the conclusion to the cadenza.

10. Notice how Mozart sets up the conclusion to these cadenzas. In the conclusion, there does not need to be a direct quotation from the Concerto, rather these sections feature florid scales and arpeggios in the style of the composition. In cadenza 1, a prominent A octave is given in the bass. This serves as a pedal tone and is on the fifth scale degree of D major, the key of this concerto. From that point a cadential 6/4 or dominant 7th chord is implied by the scale and the ending figure. The trill ends on a V7 chord leading to the tonic when the orchestra would enter.



11. We find much the same approach given in the ending of the 15th cadenza. Notice that the dominant, here G, is emphasized in the bass, followed by arpeggiated figures for a cadential 6/4 chord which lead again to the V7 and the I.



The 9th cadenza follows the same pattern as well.

12. To create a cadenza ending, begin by identifying the dominant of the key signature and creating a pedal tone section that implies the harmony of cadential 6/4 or the dominant chord. Since single line instruments cannot provide the V7 during a trill, as Mozart does with the piano, I find that presenting the dominant or dominant 7th in this conclusion is particularly effective.

13. In my cadenza, I create the dominant pedal tone area by first given a half note on F, which is the dominant of Bb, the key of the concerto. I then emphasize it in the lower octave to establish that F as the pedal tone of this last section. See the notes in the red box.



14. I then emphasize the dominant chord—F, A and C—throughout the conclusion. I have highlighted some of the chord members that are most heavily emphasized.



Vincent sets up the dominant pedal in a manner similar to my cadenza.



15. The harmony of his ending is, however, a bit more complicated. Much of the conclusion is devoted to the dominant chord through either metrically emphasized notes or arpeggios. Briefly, however, the cadenza returns to the Cadential 6/4 before implying the dominant seventh conclusion on the trill.



16. Now that you have seen several examples of conclusions to cadenzas, try writing a few now. Once you have done that you will be ready to view the next video where I will discuss writing opening statements and the middle sections of cadenzas.
