On this same program was composition simply entitled Flute Concerto by Christopher Rouse. Like Cahokia, this is an engaging composition that employs minimalist structures. To be performable, this harp part also required some editing.
One passage, employing harmonics, is not viable since it uses notes in the higher register where the strings are shortest. The execution of harmonics requires some string space, especially for the left hand that uses the palm in order to dampen part of the string. Also, these harmonics are marked double forte suggesting that they are intended to be heard. Inasmuch as there is a dense and loud orchestration at this point in the music, it is quite likely that harmonics would be lost. In addition, there are required pedal changes and rhythmic issues occurring at the speed of 176 per quarter note. I took out the harmonics and played the notes indicated with one hand in the high register where the sound can be quite piercing. This made it within the realm of possibility for these punctuating sounds to be audible. Removing the distraction of placing the harmonics made it possible to deal with the rhythmic and pedal issues.
In another section, there were glissandos doubled between the hands after which there were notes in the bass. At the speed indicated, it was very difficult to play the bass notes since, for accuracy, they needed to be placed ahead of time. I took out the doubling so that the left hand could render the proper placing.
In this same work is a repeated minimal type pattern that requires considerable speed. The left hand spacing requires a wide stretching of the hand making it awkward to replace the notes precisely each time. The manner in which this is written does not make it possible to play the figure in a facile manner. I rearranged some of the notes so that the intended effect was preserved while making it possible to play the figure fluently.
