Punch holes on paper tape to write music. Then inset the tape into the music box movement 2. Rotate the crank clockwise and you will hear the music a few seconds later 3. When music ended, keep on rotating crank till paper tape comes out About Writing Music On Paper Tape: Tape ranges 50 beats or 100 half beats. Horizontal tap is sharp, longitudinal tap is half beats, two solid lines is a beat The movement read notes through rotation of 15-pin shaft and make sound by moving soundboard. Within a circle of shaft rotation, if a sound of a pitch appears more than once (such as 11, two sounds are very close to each other, and on paper tape, 2 holes of C sound are punched on adjacent solid line and dotted line). The later sound will be ignored after first sound is read (adjacent 1/4 beat sound of the same pitch will also be ignored). Therefore, in some cheerful melody and chords, such as 15351535, the 5 repeats too much and the music might come out as 153153. You can try to recompose chord and melody. It allows 1/4 beat, and just punch hole in between solid line and dotted line In a nutshell, the min note interval thi movement can identify is half of the interval between solid line and dotted line 15-note movement range is narrow, so consider first whether it is possible to write your favorite music on tape Note: 1. Use a proper glue to fix 2. It can be fixed in an appropriate box or case to amplify the volume Package Included: 1 x Music Box Movement 1 x Hole Puncher 20 x Blank Paper Tapes
