Pass 1: The Air Slur (No articulation) Play Group 1 (Simple 2-note slurs) without tonguing. Just "Hoo, Hoo, Hoo." This verifies that your air is doing the work, not your tongue. Clarke used pressure
Pass 2: The "Dah" Middle Articulate the first note of each slur very softly ("Dah"), but do not re-articulate the higher note. Listen for a clean "pop" into the upper register without a smear.
