The application of the Internet of Things (IoT) specific to Music technologies is referred to as Internet of Musical Things (IoMusT). This field is in its infancy but potential applications include wide network interactive music performances, smart and wearable instruments, and multi-person virtual music systems. There is no framework as of yet, but a number of technical hurdles have yet to be overcome. These obstacles reflect the fact that many devices will be wearable which means they must be lightweight, energy efficient, and possibly low cost, but must also be powerful. Music therapy is yet untouched by these new technologies of IoMusT. However, it offers great potential for devices that could be applied in assistive living scenarios that provide a non-invasive, individually attuned, form of treatment that is always available. For example, wearable devices that are driven by low cost computing could offer interactive music therapies that are delivered outside of the clinical setting. These could be used to enhance a patient’s wellbeing in between instruction and practice sessions with a therapist. The usefulness of ubiquitous music technologies will be further extended with the development of machine learning algorithms that are designed specifically to have a low computational footprint. These could be used to analyze and predict user behavior and thus tailor the therapy exactly on each occasion. This paper will develop a review of what has been achieved in this domain so far. It will then look ahead to see which trajectories are most likely for the future, particular within the guiding framework of ubiquitous music and computing. It will close with a discussion on the key technological enablers and risks that could hamper their progress.
