High deep serve

The Serve
The serve should be learned first, since all rallies start with one. Also, it is through the serve that a player begins to "control the point."
The rules state that, when serving, you must stand in the service court, and your feet must both stay in contact with the floor until after the shuttle is hit. During your arm action, your racket must contact the shuttle below your waist, and the entire head of your racket must be below your hand.

High, Deep Serve
The high, deep service is used primarily in singles play. If not hit by your opponent, this serve should land as close as possible to his or her back line. The objective is to move your opponent deep into the backcourt.
Take a position approximately 2 to 3 feet from the front service line and close to the centerline. (The point where the centerline meets the front service line is often called the 7.) Stand with your feet comfortably apart (about shoulder width), with your racket-side foot back (the right foot for right-handed players). Your knees should be slightly bent.

Hold the shuttle by its cork base between the thumb and the index and middle finger of your left hand. Extend your left arm outward in front of the right shoulder. This allows you to hit the shuttle near waist level and in front of you. Many beginners tend to hold the shuttle low, near waist level, then drop it. This forces them to hit it at too low a point. You always want the shuttle at as high a point as is legally possible.

Your right wrist will be cocked up and back so that the racket head will be raised and the wrist will be at or above waist level. Your weight will be on your rear (right) foot.

As you drop the shuttle in front and to the side of your body (at about a 45-degree angle), your weight will shift forward (to your left foot), and you will swing the racket through the shuttle. At the contact point, the entire head of the racket must be below the level of your hand and below waist level.

Your body rotates in the direction of the shuttle's flight, and your wrist straightens and snaps the racket through the shuttle. You should be hitting up and out.

Follow through over your left shoulder, and let your forearm continue its rotation. Remember that you are not allowed to move or slide either foot until after contact is made with the shuttle.

The only difference in your stance between serving from the right and left courts is that when you are serving from the left, your back foot will be farther behind your front foot.

The most common error for beginners is bringing the racket forward before dropping the shuttle. This results in missing it completely—a fault.
Since the shuttlecock is very light and designed to catch a great deal of air in its flight, it drops slowly. Your racket swing must compensate for this slow drop. So the idea is to drop the shuttle and then hit it after it is already dropping.
