Tip #49 – Bending Through a Melody With Blue Notes

Let’s start by answering a question that you probably had: “What is a blue note?”

And the answer is actually not set in stone… because there are two alternating definitions of “blue notes.”

The first definition comes from the idea of what scale degrees are changed from a major scale to a regular minor blues scale. Those would be the:

| b3 – b5 – b7 |

So, by this first definition, anything out of the ordinary from the major scale of the key that acts as a flattened-3rd, 5th, or 7th scale degree qualifies as a “blue note.”

The other definition goes smaller, into quarter-tones. This states that blue notes are even further out of tune with the standard major scale, being quarter-tones apart (either higher or lower in pitch) from the said flattened-3rd, 5th, or 7th scale degrees.

If the instrument you are writing for has the capability of hitting quarter-tones (with bends, slides, tunings, etc.), play around with incorporating those notes from around the flattened-3rd, 5th, or 7th scale degrees. If not, just use the simpler definition of blue notes to achieve a bluesy sound.
