To widen the range of expression of display in an input interface.SOLUTION: A CPU of an electronic musical instrument controls, among a plurality of light emitters of a ring for input, a light emitter corresponding to a contact point or proximity point at which an operation body is in contact with or in proximity to a detection surface and which is detected by a detector to emit light with a relatively higher intensity than that of another light emitter, and controls, while the operation body is moving along the plurality of light emitters in a state in which the operation body is in contact with or in proximity to the detection surface, to gradually reduce a luminous intensity of a light emitter corresponding to a point where the operation body is no longer in contact with or in proximity to the detection surface and to turn off the light in a fixed time.SELECTED DRAWING: Figure 5 【課題】入力インターフェースにおける表示の表現の幅を広げることである。【解決手段】電子楽器のＣＰＵは、入力用リングの複数の発光部のうち、検出部によって検出された操作体と検出面との接触箇所又は近接箇所に対応する発光部を、他の発光部に対して相対的に大きな強度で発光させるよう制御するとともに、操作体が検出面に接触又は近接した状態で複数の発光部に沿って移動する際に、操作体による接触又は近接が検出されなくなった箇所に対応する発光部の発光強度を段階的に小さくしていき、かつ一定の時間で消灯するよう制御する。【選択図】図５
