Blue Notes

Blue notes are musical notes that are slightly lowered in pitch, creating a distinctive sound often associated with blues, jazz, and rock music. They typically include the third, fifth, and seventh notes of a scale, which, when flattened, evoke feelings of sadness or expressiveness. For example, in the key of C, a blue note might be the E♭ instead of the E natural. This subtle alteration enhances emotional depth and adds character to melodies, making blue notes a critical element in the improvisation and overall mood of various musical styles.
