Reader,
I recently worked with a student who was frustrated with their blues soloing. They felt everything sounded plain and vanilla.
When I heard them play, they were actually making good note and rhythm choices. The fundamentals were solid. But they weren't playing with any meaning. It was like reading lines from a book in a monotone voice.
We worked on their articulation and embellishments. The same fundamental lines suddenly sounded super hip. Nothing about the melody changed, but everything about the delivery did.
Blues embellishments are like the inflection in your voice when you speak.
Last week, you built your foundation with chord tones and the blues scale. This week, we're adding the personality. Think of it this way: the house is your foundation, but the paint colors, artwork, and rugs give it feel.
