Abstract: A musical composition system, includes a plurality of tokens (5-7) of visibly distinct types, each representing aspects of at least a fragment of a musical composition, wherein the tokens are configured for placement by at least one user in a spatial configuration; a system for determining respective locations and types of an assembly of tokens (5-7) placed in a spatial configuration by the user(s); a system (13-16;44-46) for translating a spatial ordering of the tokens (5-7) in the spatial configuration into a temporal ordering; a system (13,18,40;44-46) for translating the types of the tokens (5-7) into respective aspects of at least a fragment of a musical composition; and a system (13,18-20;44-46) for generating at least one signal representing a synthesis of the respective aspects of fragments of a musical composition in accordance with the temporal ordering, the signals being suitable for audible reproduction.
