When I play jazz on the saxophone, I use a technique I was taught called "Jazz Articulation" (I'm sure that's not its only name) which is basically an articulation where you slur every other note with a tongue in between while playing straight eighth-notes to give your sound a swing feeling.
I was also taught that "faking" swinging eighth-notes, which is basically intentionally shortening and lengthening the notes to give it a swing feel, is bad practice and should be avoided
This jazz articulation works all fine on the saxophone but on the piano, this isn't really possible as my air flow isn't controlling the sound coming out of the piano. How do I swing eighth-notes on the piano and not make it sound like I'm trying to create a "fake" swing sound?
And/or, is the advice I was told incorrect/inaccurate?
