Abstract: An electronic musical instrument comprising a plurality of keys that includes a first and a second key having a pitch in a harmonic relationship with a pitch of the first key; and at least one processor. wherein the at least one processor performs the following: deciding, in response to a operation of a first key, whether the second key is in a damped state or in a non-damped state; generating, in a case where the second key is in the non-damped state, a resonance tone corresponding to the second key with at least one of a first resonance pitch and a first timbre; and generating, in a case where the second key is in the damped state, the resonance tone corresponding to the second key with at least one of a second resonance pitch and a second timbre.

Abstract: A resonance strength table is prepared, which stores a relation between a pitch difference and a resonance strength, wherein the pitch difference is a difference between a pitch assigned to the key number of a pressed key and a pitch assigned to each of key numbers of a resonance tone. When a key is pressed, the resonance strength table is referred to, and resonance strengths concerning the key numbers of a resonance tone are determined. Then, note-on events of a resonance tone are produced based on the key numbers and the decided resonance strengths and the produced note-on events are sent to a sound source.

Abstract translation: 制备谐振强度表，其存储音调差和谐振强度之间的关系，其中音调差是分配给按下的键的键数的音高与分配给每个键编号的音调之间的差 共鸣音。 当按下键时，参考共振强度表，并且确定关于谐振音的键数的共振强度。 然后，基于键数和所确定的共振强度产生共鸣音的音符事件，并将产生的音符开启事件发送到声源。
