Abstract: A bell and method of tuning a bell with its lowest frequency partials at f1=f and f2=3f=2. The simultaneous presence of physical tones at these partial frequencies yields a difference tone, perceived by the listener, at f2f1=3f=2f=f=2. The difference tone is subharmonic, in that its perceived frequency (f=2) is below the frequency of the fundamental (f). Preferably, the bell has one or more additional partials at frequencies fn=(n+1)f=2, with n 2 f3; 4; 5: : : g, strengthening the listener's perception of the difference tone at f=2. The bell thus yields a strike tone at f=2 but has a characteristic dimension (e.g. height or diameter) equal to that of conventional bells with a strike tone at f, providing art eightfold savings in bell mass.

Abstract: The present disclosure provides a performance apparatus capable of changing to a performance pattern making a musically natural transition. A CPU 13 determines which stage a performance pattern of each of tracks Tr (1) to (4) currently selected belongs to, and obtains the number of performance patterns for each stage, in accordance with depression of a transition button. The CPU 13 determines that the stage having the maximum number of performance patterns is the “current stage” among the number of performance patterns for each stage obtained, and changes the performance pattern of each of the tracks Tr (1) to (4) to the stage subsequent to the determined “current stage”. Therefore, the performance pattern can be changed into a performance pattern making a musically natural transition. As a result, even a beginner user being poor in music knowledge can set an appropriate performance pattern matching the transition of the song.
