Duke Jordan’s “Jordu” (or Jor-du) is an excellent tune for memorizing the sound of the ascending perfect fourth interval. The first three phrases of the A section all start with the same perfect fourth, so if you listen to the entire head (AABA) you will hear it nine times.
Here is the first phrase:
- Clifford Brown and Max Roach, Clifford Brown & Max Roach, 1954
- Duke Jordan, Flight To Denmark, 1974
- Mulgrew Miller, Solo, 2010
