Abstract
According to the present invention, there is provided an electronic musical instrument, comprising: a plurality of keys; a memory that stores each pattern data showing a combination of a plurality of pitches that comprises a consonance; a speaker; and a processor that executes the following: determining processing for determining whether a combination of the operated keys matches any of the pattern data stored in the memory, first outputting processing for outputting a first sound, when the combination of the operated keys matches any of the pattern data, and second outputting processing for outputting a second sound, when the combination of the operated keys does not match any of the pattern data.

An electronic musical instrument, comprising:
- a plurality of keys that specify different pitches respectively when operated;
- a memory that stores pattern data, each pattern data indicating a combination of a plurality of pitches forming a consonance;
- a speaker;
- and
- a processor that executes processing comprising:
- determining processing for determining, in response to an operation of the plurality of keys, whether a combination of the operated keys matches one of the pattern data stored in the memory,
- first outputting processing for outputting a first sound from the speaker, when the combination of the operated keys matches one of the pattern data, wherein the first sound is generated based on both the pitches specified by the operated keys and sound volume information obtained by the operation, and
- second outputting processing for outputting a second sound different from the first sound from the speaker, when the combination of the operated keys does not match any of the pattern data, wherein the second sound is generated independently of at least one of the pitches specified by the operated keys and the sound volume information obtained by the operation.
An electronic musical instrument, comprising:
- a plurality of keys that specify different pitches respectively when operated;
- a speaker;
- and
- a processor that executes processing comprising:
- sorting processing for sorting pitches corresponding to operated keys in order from a lowest pitch to a highest pitch or from a highest pitch to a lowest pitch,
- grouping processing for grouping pitches into a plurality of groups including a group including first pitch and a group including second pitch when a pitch difference between the first pitch and the second pitch, which are adjacent to each other after the sorting performed in the sorting processing, is a major third or larger,
- first outputting processing for determining that the operated keys are not in a dense state when a pitch difference between any adjacent pitches among pitches included in any of the groups obtained in the grouping processing is not a major second or smaller, and outputting a first sound from the speaker, wherein the first sound is generated based on both the pitches specified by the operated keys and sound volume information obtained by the operation, and
- second outputting processing for determining that the operated keys are in a dense state when pitch differences between all adjacent pitches included in any of the groups obtained in the grouping processing are a major second or smaller, and outputting a second sound from the speaker, wherein the second sound is generated independently of at least one of the pitches specified by the operated keys and the sound volume information obtained by the operation.
A method executed by a computer of an electronic musical instrument that includes a plurality of keys that specify different pitches respectively when operated, a memory that stores pattern data, each pattern data indicating a combination of a plurality of pitches forming a consonance, and a speaker, the method comprising:
- determining, in response to an operation of the plurality of keys, whether a combination of the operated keys matches any of the pattern data stored in the memory,
- outputting a first sound from the speaker, when the combination of the operated keys matches one of the pattern data, wherein the first sound is generated based on both the pitches specified by the operated keys and sound volume information obtained by the operation, and
- outputting a second sound different from the first sound from the speaker, when the combination of the operated keys does not match any of the pattern data, wherein the second sound is generated independently of at least one of the pitches specified by the operated keys and the sound volume information obtained by the operation.
A method executed by a computer of an electronic musical instrument that includes a plurality of keys that specify different pitches respectively when operated, and a speaker, the method comprising:
- sorting pitches corresponding to operated keys in order from a lowest pitch to a highest pitch or from a highest pitch to a lowest pitch,
- grouping pitches into a plurality of groups including a group including first pitch and a group including second pitch when a pitch difference between the first pitch and the second pitch, which are adjacent to each other after the sorting of, is a major third or larger,
- determining that the operated keys are not in a dense state when a pitch difference between any adjacent pitches among pitches included in any of the groups obtained in the grouping is not a major second or smaller, and outputting a first sound from the speaker, wherein the first sound is generated based on both the pitches specified by the operated keys and sound volume information obtained by the operation, and
- determining that the operated keys are in a dense state when pitch differences between all adjacent pitches included in any of the groups obtained in the grouping processing are a major second or smaller, and outputting a second sound from the speaker, wherein the second sound is generated independently of at least one of the pitches specified by the operated keys and the sound volume information obtained by the operation.
