Electronic Device Ad-lib Music Section Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic musical instrument lessons are inadequate for ad-lib performance, as they either reproduce the entire piece as guidance, which is not suited for improvisation, or lack guidance, making it difficult for users to practice effectively.
Innovation Solution
An electronic device that determines and controls guide performance sections and ad-lib performance sections within a piece of music, allowing music sound to be output in guide sections and not output in ad-lib sections, enabling users to perform ad-lib improvisations while maintaining the progression of the music.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire piece of music is reproduced as guidance, then the user can follow along with complete musical support, but this prevents effective ad-lib performance practice by providing too much guidance
Solution Approach 1:
The piece of music is divided into multiple sections with different guidance levels. Some sections provide complete musical guidance while others provide reduced or no guidance, allowing users to practice improvisation in specific segments while maintaining structure in others. This segmentation enables differentiated learning experiences within a single piece.
Solution Approach 2:
The guidance level is made dynamic by allowing automatic switching between different reproduction modes (complete reproduction, reduced reproduction, no reproduction) based on section type. This dynamic adjustment enables the system to adapt the amount of guidance provided during performance, balancing structure and improvisation opportunities.
2Adaptability or versatility
If no guidance is provided for ad-lib performance, then users have freedom to improvise, but this increases difficulty and reduces effectiveness for learners needing structure
Solution Approach 1:
Different sections of the music are assigned different qualities of guidance. Some sections maintain full musical guidance for structural support, while other sections reduce or remove guidance to enable improvisation. This local differentiation allows users to experience both structured learning and creative freedom within the same performance context.
3Extent of automation
If the music reproduction is fully automatic, then the lesson delivery is consistent and reliable, but this reduces flexibility in adapting to different learning stages and performance types
Solution Approach 1:
The automatic reproduction system employs periodic switching between different reproduction modes (complete reproduction, reduced reproduction, no reproduction) according to predefined section markers. This periodic action allows the system to automatically adapt its behavior at different points in the music, providing structured guidance when needed and enabling improvisation at other times.
Data Source
AI summary
An electronic device including at least one processor that controls reproduction of a piece of music based on music data. The processor determines a performance section falling under a condition defined in advance in the piece of music as a first section and determines a section not falling under the condition as a second section, and in reproducing of the piece of music based on the music data, controls to output music sound of the first section and not to output at least a part of music sound of the second section.
