Numerical continuation of a physical model of brass instruments: Application to trumpet comparisons Open
The system formed by a trumpet player and his/her instrument can be seen as a non-linear dynamic system and modeled by physical equations. Numerical tools can then be used to study these models and clarify the influence of the model parame…
