A nice summary of the musical acoustics of brass instruments is given by Campbell [70].
Research by Cullen et al. [98] and Gilbert et al. [160,162] has been concerned with artificial mouth experiments to verify a theoretical model of vibrating lips, and to calibrate the model to realistic playing conditions. These data can be used in the construction of improved lip-valve models for virtual brass instruments. Additional literature relevant to brass instruments includes [188,187,189,249,533,322,334,339,538,539,540,448,93].
