A music timer comprises a timing unit, a music box unit and its mounting frame, a music control wheel (29) that has a gap (291) along its edge is driven to rotate by a driving gear through rotary axis of the driving spring of the timing unit; one end (3a) of a brake rod (3) always abuts against the edge of said music control wheel (29) and the other end (3b) extends into the damping mechanism of the music box unit to activate it when the end (3a) abuts against the non-gap places on said music control wheel, whereas when the end (3a) sinks into the gap (291) of said music control wheel, the end (3b) then departs from the damping mechanism of the music box unit, thus producing no influence on its movement. The present invention enables the timer to produce pleasant and lasting music at the end of the timing. Moreover, through the scientific spatial arrangement of the present invention, and the projected cross section of the device is much smaller than the sum of those of the timer and the music box unit.
