What is a trombone?
BRASS FAMILY
The sound of all brass instruments is produced when the player vibrates his or her lips (it is known as embouchure) causing a vibration in the air column inside the trombone.
The trombone is usually described and characterized by its telescopic slide on which the player adjusts the length of the tube to change its pitches.
POSTURE
When standing, stand up straight, look straight ahead of you. Breathe normally, relax your shoulders.
When you sit and play, sit upright, as if you were standing. Stand from the waist up, sit from the waist down, with feet flat on the floor in front of you. Your posture from the waist up should be the same as when standing. Your goal is to stand or sit strong, proud, yet relaxed.
Use a mirror to check your posture. Look at your face, neck, shoulders, and waist. Take a full deep breath and let it out slowly.
