Answer:
True
Step-by-step explanation:
A "blue note" in music generally refers to a slight drop in pitch on the third, fifth, or seventh scale tone, which is commonly used in blues and jazz music to create a specific mood or feeling. The blue note is often played with a bent or flattened pitch, which adds a distinct and expressive quality to the music. The use of blue notes is an important characteristic of blues and jazz music, and it has had a significant influence on many other genres of popular music as well.
