Solution Overview

Problem

Children using electronic musical instruments often produce random and dissonant sounds due to their early developmental stage, leading to boredom and loss of interest without proper instruction, as conventional instruments do not differentiate between correct and incorrect key combinations.

Innovation Solution

An electronic musical instrument with a processor and memory that determines whether key combinations match stored pattern data for consonance, producing a first sound when correct and a second sound when incorrect, incorporating special sound producing processing to engage users by differentiating between normal and random playing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional keyboard produces pitches for all pressed keys regardless of combination, then the instrument maintains simple operation and produces musical tones, but children produce random dissonant sounds and become bored without proper instruction

Engineering Contradiction:
Improveease of operationVSAvoidmusical quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system provides immediate feedback by detecting key combinations and determining whether they form consonant or dissonant chords. When dissonant combinations are detected (indicating random playing by children), the system outputs a different sound to guide them toward correct playing, while still allowing normal tone production for correct combinations.

Inventive Principle:
Principle #23Feedback

2Loss of information

If the instrument provides instruction on proper playing without instructor, then children can learn correct chords and performance, but the device complexity increases to detect and evaluate key combinations

Engineering Contradiction:
Improveinstructional informationVSAvoiddevice complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The electronic musical instrument performs self-instruction by automatically detecting key combinations, determining whether they form consonant or dissonant chords, and providing appropriate feedback through different sound outputs. This eliminates the need for external instructors while maintaining relatively simple device architecture.

Inventive Principle:
Principle #25Self-service

3Reliability

If the instrument differentiates between correct and incorrect key combinations with different sounds, then children receive feedback to learn proper playing, but the device complexity increases due to pattern matching and determination processing

Engineering Contradiction:
Improveinstructional accuracyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system stores multiple pieces of pattern data representing consonant chord combinations in advance. During operation, the processor simply compares detected key combinations against these pre-stored patterns to determine whether they form consonant or dissonant chords, eliminating the need for complex real-time analysis.

Inventive Principle:
Principle #10Preliminary action

AI summary

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.
