Physical modelling allows the user to think in terms of the underlying physical shape and construction of the acoustic instrument, whether it be a musical instrument or a singing/speaking human. Basic physical structures that are familiar as elements of acoustic musical instruments, such as strings, membranes and blocks, can exist in the virtual world of physical modelling, where these structures are 1, 2 and 3 dimensional respectively. The structures themselves consist of a large number of unit elements connected together in 1, 2, or 3 dimensions. Such structures can be used for the synthesis of music, speech and singing.
