On a trombone, a player may provide a slightly more pronounced vibrato by gently moving the slide back and forth, centering on one note to give a lyrical effect. Often this is more of a jazz technique, and is called "slide vibrato". In brass playing, "diaphragmatic vibrato" is possible, but is viewed as an immature technique by collegiate or professional brass players as this technique interferes with proper airflow from the lungs to the instrument. The use of diaphragmatic vibrato in a brass setting is detrimental to the sound and stamina that a brass player can produce, and so is strongly discouraged at any level of musical training.
