Embodiments are generally directed to methods, systems and devices for generating and playing back a personalized state song representing a target state of a user. In one scenario, a computer system accesses biometric data corresponding to various bodily systems of a user. The computer system encodes the biometric data into data structures that are configured for modeling using an algorithm that is specific to the user. The computer system models the encoded biometric data to identify specified patterns in the encoded biometric data, and these identified patterns are used to generate a personalized algorithm that corresponds with the identified patterns unique to the user. The computer system then synthesizes a state song using the personalized algorithm, which represents a specific biometric state for one of the bodily systems, and plays back the state song to the user to induce the user to the specific biometric state.
