Electronic stringed instrument, musical sound generation method and storage medium

A musical sound generation method used in an electronic stringed instrument, the electronic stringed instrument including:

• a plurality of strings stretched above a fingerboard unit provided with a plurality of frets;
• a state detection unit that detects a state between each of the plurality of frets and each of the plurality of strings;
• and a string picking detection unit that detects that any of the plurality of strings is picked while detecting the strength of detected string picking, the method comprising:
• determining whether or not the level of string picking strength detected by the string picking detection unit exceeds a predetermined first level;
• determining by the state detection unit, in a case where the predetermined first level is exceeded, whether or not a condition is satisfied that there are a plurality of frets simultaneously in contact with the string detected as a picked string by the string picking detection unit through the state detection unit;
• and
• instructing, in a case where the condition is satisfied, a sound source to generate a predefined slap sound.

A non-transitory storage medium storing a program configured to cause a computer used in an electronic stringed instrument, the electronic stringed instrument including:

• a plurality of strings stretched above a fingerboard unit provided with a plurality of frets;
• a state detection unit that detects a state between each of the plurality of frets and each of the plurality of strings;
• and a string picking detection unit that detects picking of any of the plurality of strings while detecting strength of detected string picking, to execute:
• a level determination step of determining whether or not the level of string picking strength detected by the string picking detection unit exceeds a predetermined first level;
• a condition determination step of determining, in a case where it is determined in the level determination step that the predetermined first level is exceeded, whether or not a condition is satisfied that there are a plurality of frets simultaneously in contact with the string detected as a picked string by the string picking detection unit through the state detection unit;
• and
• a slap sound generation instruction step of instructing, in a case where it is determined in the condition determination step that the condition is satisfied, a sound source to generate a predefined slap sound.
