Electronic musical instrument, electronic musical instrument control method, and storage medium

A method of controlling an electronic musical instrument that includes 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, the method comprising, via the at least one processor:

• deciding, in response to operation of the 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.

A non-transitory computer-readable storage medium having stored thereon a program executable by at least one processor in an electronic musical instrument that includes, in addition to the at least one processor, a plurality of keys that includes a first key and a second key having a pitch in a harmonic relationship with a pitch of the first key, the program for causing the at least one processor to perform the following:

• deciding, in response to operation of the 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.
