Final answer:
Mendelssohn concludes the development section in his Hebrides Overture through a sudden key change, a fast-paced coda, and the introduction of a new thematic element.
Step-by-step explanation:
In his Hebrides Overture, Mendelssohn concludes the development section by employing a sudden key change. This technique creates a sense of surprise and excitement as the music transitions to a new tonal center. The sudden key change also helps to heighten the emotional impact of the music, capturing the listener's attention and creating a dramatic effect.
Additionally, Mendelssohn utilizes a fast-paced coda to conclude the development section. The coda is a section at the end of a piece that brings it to a close and provides a sense of resolution. By increasing the tempo and intensity of the music in the coda, Mendelssohn adds a sense of urgency and excitement to the conclusion of the development section.
It is also worth noting that Mendelssohn introduces a new thematic element in the development section. This new melodic material adds variety and interest to the music, creating a sense of progression and development. By introducing a new theme, Mendelssohn keeps the listener engaged and adds a sense of freshness to the music.
