The Illuminated Instrument Strap includes fasteners to removably secure it to an instrument. A light, including a plurality of LEDs capable of generating colors, are operably connected to a control box is disposed along the length of the instrument strap. The control box which could be embedded within the belt includes or attached to it includes a battery which is rechargeable, control switches, a controller that includes a logic that is at least partially stored in a non-transitory computer readable medium. When executed at least in part by the controller the logic causes the light to illuminate in a pre-programmed pattern generated from the logic. Alternatively, the controller is adapted to generate a pattern from an audio input information obtained from a microphone, or from a signal received from a musical instrument, such that illumination of the light is synchronized to the audio input or the musical instrument signal thereby creating a music visualization pattern.
