As you can see from the picture below, the flute is not parallel to the shoulders.
Turn your chair to the right at approximately a 45 degree angle, then turn your upper body and your head so that you're looking over your left elbow.
The flute should make an angle or pie-shaped wedge between the line of your shoulders and the line of the flute's body. Guiding the foot joint away from you with the right hand should allow a relaxation of your left shoulder down and into its socket.
Don't worry if this seems like a lot of details to keep track of. After a bit of practice this will seem natural.
Once you are comfortable with this you will be ready for the next lesson and your first note!
