Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic practicing apparatuses for keyboard musical instruments struggle to help users gradually increase the range of practiced music, making it difficult to maintain connections between musical phrases and expressions in a cohesive performance.
Innovation Solution
A musical performance apparatus with a processor that determines target phrases for practice, allowing users to select and connect additional phrases, enabling the practice of connections and expressions within a musical piece by displaying recommended connection destinations and scoring user performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If each phrase is practiced separately using conventional automatic practicing apparatus, then practice efficiency for individual phrases is improved, but the ability to maintain connections between phrases and expressions of the musical piece deteriorates
Solution Approach 1:
The patent divides the musical piece into multiple phrases and allows users to select specific phrases for practice. The system provides segmented practice by enabling selection of individual phrases or ranges of phrases, while maintaining the ability to practice connections between selected phrases and the overall musical expression.
Solution Approach 2:
The patent implements dynamic phrase selection where users can flexibly choose which phrases to practice and in what order. The system adapts the practice range based on user selections, allowing dynamic adjustment between practicing single phrases, multiple phrases, or the entire piece, thereby maintaining both efficiency and musical coherence.
2Stability of the object's composition
If the entire musical piece is practiced from the beginning, then connections between phrases are maintained, but the ability to focus on and repeatedly practice specific difficult phrases deteriorates
Solution Approach 1:
The patent enables users to segment the musical piece into selectable phrases, allowing focused practice on specific difficult passages while maintaining the option to practice connections by selecting larger phrase ranges or the entire piece.
Solution Approach 2:
The patent changes the practice parameter from fixed entire-piece practice to flexible phrase-range practice. Users can adjust the practice scope by selecting different start and end phrases, thereby optimizing practice efficiency for difficult passages while maintaining the ability to practice overall connections when needed.
3Ease of operation
If conventional automatic practicing apparatus provides scoring for each phrase, then motivation through feedback is improved, but the ability to guide users to practice phrase connections and expressions deteriorates
Solution Approach 1:
The patent provides scoring feedback for user performance on selected phrases, maintaining motivation through immediate evaluation. The system compares user input with model performance data and provides scores, while also providing information about recommended connection destinations to guide users toward better understanding of musical expressions.
Solution Approach 2:
The patent introduces an intermediary guidance system that recommends connection destinations based on the currently practiced phrase. This intermediary information helps users understand how individual phrases connect to the overall musical piece, preserving musical expression context while maintaining the motivational scoring system.

AI summary
A musical performance apparatus including at least one processor configured to: determine any phrase as a first phrase that is to be a performance target performed by a user from among a plurality of phrases included in a musical piece, and determine a set of phrases from the first phrase to a second phrase to be phrases that are to be the performance target performed by the user according to operation by the user in order to select the second phrase from the plurality of phrases.
