Musical Score Display with Dynamic Note Highlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional music practice tools, such as music boards and electronic keyboard performance guides, fail to enhance the learning effect of music pieces by not providing a clear visual representation of note relationships and automatic progression, making practice less engaging and ineffective for mastering musical scores.
Innovation Solution
A performance assistance device that displays a musical score image with notes on a time and pitch axis, acquires pitch information, and changes the display style of matching notes or positions, allowing users to visually identify corresponding notes and practice music pieces more efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a music board is used to display key-position correspondence, then users can master musical scales, but users cannot effectively master music piece performance and score reading
Solution Approach 1:
The display device is designed to serve multiple functions: it displays key positions like a traditional music board, simultaneously displays musical score images with notes arranged on time and pitch axes, and provides performance guidance by highlighting matching notes. This multi-functionality resolves the contradiction by making a single device adaptable to both scale mastering and music piece performance training.
Solution Approach 2:
The invention merges the functionality of a music board (key-position display) with a musical score display system and performance guide function. By combining these previously separate tools into one integrated system, the device can simultaneously provide key-position correspondence and music piece performance guidance, eliminating the need to choose between scale training and performance training tools.
2Ease of operation
If a performance guide function illuminates keys to be depressed, then users can follow along with music pieces, but the guide automatically advances positions preventing users from practicing at their own pace
Solution Approach 1:
The performance guide function is designed to be dynamic and responsive to user input rather than automatically advancing. The system allows users to control the progression of the music piece at their own pace, providing flexibility and adaptability while maintaining ease of operation through visual guidance.
Solution Approach 2:
The system enables users to self-direct their practice by allowing them to advance or review positions according to their own needs. Rather than the system imposing a fixed progression, users have control over the practice flow, making the system adaptable to individual learning paces and styles.
3Ease of operation
If conventional tools display only current position notes, then users can focus on immediate tasks, but users cannot grasp overall note relationships and patterns in the music piece
Solution Approach 1:
The display device presents musical information in multiple dimensions simultaneously: it shows the current position notes for immediate focus while also displaying the overall musical score image with notes arranged on both time and pitch axes. This multi-dimensional presentation allows users to grasp overall note relationships and patterns while maintaining focus on current tasks.
Solution Approach 2:
The display system segments information presentation into different visual layers: the musical score image provides overall context showing all notes and their relationships, while the performance guide highlights specific current-position notes. This segmentation allows users to access both global patterns and local details simultaneously without information overload.

AI summary
A display device displays a musical score image where musical notes indicative of individual tones or sounds constituting a music piece are arranged on a time axis and pitch axis. Pitch information indicative of one or more pitches is acquired in response to an operation on a keyboard, and a note matching any one of the one or more pitches indicated by the acquired pitch information is identified from among the notes included in the musical score image. When any note has been identified as matching any one of the one or more pitches indicated by the acquired pitch information, a display style of the matching note is changed. Only when no note has been identified as matching any one of the one or more pitches indicated by the acquired pitch information, a display mode of a portion of the musical score image other than the notes is changed.
