Abstract: An improved code changing method for an electronic musical instrument with an automatic accompaniment function allows a chord code change during a play in accordance with a tone of an musical instrument being used in the current accompaniment just before a new code representing a new chord is inputted for the next music play. The method includes judging the possibility of a slur processing by recognizing a tone being used in the automatic accompaniment when the new code information is inputted, performing the slur processing when the slur processing is judged to be possible, and performing a retriggering process or an automatic accompaniment by neglecting the new code information, when the slur processing is judged to be impossible.

Abstract: A non-wound three-piece golf ball which comprises an inner core, an outer layer and a cover, the inner core having a diameter of 23-35 mm and a hardness (Shore D) of 30-62, the outer layer having a diameter of 36-41 mm and a hardness (Shore D) of 30-56, the golf ball having a hardness (Shore D) 46-62 at the outer site in the inner core, which is 11.5-17.5 mm apart from the center of the ball. The golf ball has a maximum hardness (Shore D) in the range of 46-62 at the outer site of the inner core which is located at the interface between the inner core 1 and the outer layer 2 of the golf ball and the hardness then decreases both inwardly and outwardly.
