Abstract: The systems and methods of illuminating instrument features disclosed herein provide for the illumination of the interior of an instrument, such as an acoustic guitar with a “sound hole”, and a drum, among others, with an illumination source (a non-limiting example is light emitting diodes (LEDs)). One or more illumination sources may be attached to the inside of the instrument to direct light such that the hole is illuminated. The illuminated opening may reveal as non-limiting examples, logos, art work, messages, wording, and text, among others.
