Open areas of vibrating lips in trombone playing
In brass instruments the player’s lips are used as a control valve that allows an oscillating flow of air into the instrument. The behaviour of this valve, the lip-reed, is determined by both the pressure difference across the lips and the open area between the lips. Computer simulations of brass instrument playing frequently represent the lips as an oscillating system with one degree of freedo...

متن کاملRelationships between pressure, flow, lip motion, and upstream and downstream impedances for the trombone.
This experimental study investigates ten subjects playing the trombone in the lower and mid-high range of the instrument, B♭2 to F4. Several techniques are combined to show the pressures and the impedance spectra upstream and downstream of the lips, the acoustic and total flows into the instrument, the component of the acoustic flow due to the sweeping motion of the lips, and high speed video i...
متن کاملAcoustical properties of the vocal-tract in trombone performance
The study of the acoustical in uence of the upstream (vocal-tract) airway in wind instrument performance has been a growing subject of interest in musical acoustics. In a recent study performed on trombone players, we observed a noticeable increase of the acoustic pressure near the fundamental frequency at the input of the vocal tract relative to the acoustic pressure at the input of the instru...
متن کاملWitnessing social injustice downstream and advocating for health equity upstream: "the trombone slide" of nursing.
Two aspects of a study examining the congruence of critical caring theory with public health nursing practice are reported. They confirm a congruence between expert public health nursing practice and the theory in terms of (a) a caring/social justice ethics that underpins practice and (b) the relevance to their practice of the carative health promoting process of contributing to the creation of...
