Final answer:
In a jazz ensemble, comping is typically done by the pianist. The correct option is d.
Step-by-step explanation:
In a jazz ensemble, comping is typically done by the pianist.
Comping, short for accompanying, refers to the practice of providing harmonic support and rhythmical accents to the soloists or other musicians in the ensemble. The pianist in a jazz ensemble often plays chords and syncopated rhythms to create a strong foundation and enhance the overall musical performance.
It is worth noting that other musicians, such as the guitarist or keyboardist, can also fulfill the role of comping in a jazz ensemble depending on the specific composition and arrangement.
Hence, Option d is correct.
