When music is over, keep on rotating crank till paper tape comes out. 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). Therefor, 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. If there is no better recomposition, you should consider if to write it on tape. It allows 1/4 beat, and just punch hole in between solid line and dotted line. In a word, the minimum note interval that 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: Fixed with 2 or 3 screws that are commonly used for toys or gifts with screw holes.Use a proper glue to fix. It is small, need to be fixed in an appropriate case to amplify the volume.
