Final answer:
Lester Young was known for his relaxed saxophone style and contribution to the Count Basie Orchestra, not for a flamboyant and energetic stage presence, which is the incorrect option regarding his musical and personal style. Therefore, the incorrect option is D.
Step-by-step explanation:
All of the following are true of Lester Young's musical and personal style EXCEPT he was known for his flamboyant and energetic stage presence. Young was a highly influential tenor saxophonist who had a relaxed, laid-back approach to playing. He was indeed a key member of the Count Basie Orchestra. Unlike the statement suggests, Young was not recognized for flamboyant and energetic stage antics; rather, he was known for a much more subtle and smooth stage demeanor that matched his cool sound on the saxophone.
During the Harlem Renaissance, black musicians like Young created a new style of music that expressed the experiences of life in black communities. This movement saw the birth of jazz and the evolution of blues, which artists like W. C. Handy helped popularize by bringing to sheet music. Jazz featured an upbeat tempo with improvisation, while blues contributed unique chords and blue notes to the musical landscape. Lester Young's style embodied these innovations, adding to the richness of the music during this era.
