Abstract: A smart training accessory connected to musical instrument for aiding users in learning and collaboration is disclosed. The accessory includes a plurality of sensors for collecting data pertaining to the musical instrument. A microcontroller processes the data collected by the plurality of sensors to: (a) determine a type of musical instrument to which the smart training accessory is connected and (b) generate an alert for encouraging an individual to play the musical instrument when the user enters a monitoring area within the vicinity of the smart training accessory. Furthermore, when the user plays the musical instrument, the plurality of sensors captures data including audio recordings and transmits the data to a training and synchronization system. The training and synchronization system processes the received data to generate real-time feedback for the user and further aids collaboration with other users.
