For a comfortable playing position, it is best to use a strap. A wide strap, approx. 2-3 inches (8-10cm) is best, so the weight of the bass is evenly distributed. Adjust the strap to a length that is comfortable. The full weight of the bass should be resting on the shoulder strap.
The bass should be angled slightly upwards (see photo), so that your left arm is free to move while you play. Whether you prefer to sit or stand while you play, make sure that the position of your bass (strap length and angle) is the same so that your playing won’t be affected. Keep the bass close to your body so that it is easy to reach all parts of it when you play.
Sit on a stool with a footrest to raise your right leg,or just cross your right leg over your left leg.
