Review of how to form "ng": To form the “ng” sound, open your mouth and press the back of your tongue against the back of your throat. The tip of your tongue should be low in your mouth. As you finish the sound, release your tongue gently. Do not hold your breath, as it will create an extra "g" or "k" after it. The "ng" sound is a "nasal sound" because it goes through the nose when saying it. It is also a voiced sound, so you should hear your voice when you say it.
