Often times it is more important how you practice than what you practice. To become an even average trumpet player
requires dedication. The trumpet is not an instrumet you can set down for two weeks then pick it up and play a two hour concert.
A good practice routine will contain several common elements:
A good warmup will be long enough to get the blood going and have you ready to play with minimal effort. While each player is different, a typical warmup should be between three and five minutes.
Warm up times will also vary depending on how fatigued the player is. If your lips are very tired, expect to have a longer warmup than if you are fully rested.
