Breathe using the diaphragm muscles to expand your lungs and take in air. When you play, make sure to keep the airflow steady and consistent.
Ensure that the tip of the tongue always hits the reed lightly and briefly cuts off the airflow when tonguing.
Practice creating a hard tonguing by forming the sound "tah" with your tongue.
Play a softer, legato tonguing by forming the sound "dee" with your tongue.
Play major scales each day, using both types of articulations. Start by playing four notes of the scale per beat at the metronome marking of 52 beats per minute. Increase the speed by two beats per day until you can play scales at 120 beats per minute.
