In IFR Exercise 1: Landscape, one of our very first exercises is to move around the musical terrain by any given interval. We call this exercise "Staircase" to remind us of the image of a child playing on a staircase. As you practice Staircase, try to maintain this spirit of playfulness and creativity in your movement.
In this video Marina Vallet demonstrates the exercise on the soprano saxophone using the interval of the whole step.
