A musical toy shaped like a rainbow or a banjo which generates musical sounds in response to interruption of one or more radiation beams is disclosed. In one embodiment, the musical toy is provided with a frame member (202) having a substantially unobstructed aperture (206) disposed therein, a photoemitter (212) for generating a radiation beam across the aperture (206), a photodetector (216) positioned to receive the radiation beam, an audio generator for generating a plurality of temporally successive portions of a predetermined musical song, and a play mechanism for causing the audio generator to generate one of the temporally successive musical song portions in response to each interruption of the radiation beam so that repeated interruption of the radiation beam causes the predetermined musical song to be played. In a second embodiment, the musical toy has a base member (12), a second member (14) connected to the base member (12) so as to form a substantially unobstructed space (15) therebetween, a plurality of photoemitters (22) for generating radiation beams between the base member (12) and the second member (14), a plurality of photodetectors (20) each positioned to receive a respective one of the radiation beams, an audio generator for generating a plurality of musical sounds each of which is associated with a respective one of the radiation beams, and a mechanism for causing the audio generator to generate one of the musical sounds in response to an interruption of the radiation beam associated with the one musical sound.
