Musical Score Display with Iteration Time Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to visually understand the relationship between a musical score and its time axis, especially when repeat signs are involved, as existing systems do not effectively convey the number of iterations or designated positions during performance.
Innovation Solution
A musical score display control device and method that generates and displays first time axis information representing actual performance with repeat parts played out, along with repeat part identification information, and allows users to designate positions on a second time axis for improved user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only a time axis representing the entire performance length and current position are displayed, then the display is simple, but it is difficult for users to visually recognize the number of iterations and relationship between musical score and time axis
Solution Approach 1:
The time axis is segmented into multiple regions corresponding to different repeat iterations. Each iteration is visually separated and labeled, allowing users to distinguish between first iteration, second iteration, etc. This segmentation preserves complete performance information while maintaining visual organization.
Solution Approach 2:
The patent introduces a vertical dimension to the time axis display by stacking multiple iteration timelines vertically. This transforms a one-dimensional time representation into a two-dimensional display where the vertical axis represents iteration number and the horizontal axis represents time, enabling users to visualize repeat structures clearly.
2Ease of operation
If repeat part identification information is displayed for each iteration, then user understanding of repeat structure is improved, but the display becomes more complex
Solution Approach 1:
Different visual styles are applied to different regions of the time axis based on their function. First iteration regions use one visual style, while subsequent iterations use another style. Repeat start and end positions are marked with distinctive symbols. This local differentiation helps users quickly understand the repeat structure without overwhelming detail.
Solution Approach 2:
The patent uses color coding to distinguish between different repeat iterations and types. First iterations may be displayed in one color, while repeated iterations are displayed in another color. This visual differentiation allows users to immediately grasp the repeat structure and current position without complex labels or symbols.
3Loss of information
If the time axis shows the entire performance length including all repeats, then the relationship between score position and performance time is clear, but the display area required increases
Solution Approach 1:
By stacking multiple iteration timelines vertically, the patent compresses the horizontal space required to display the entire performance length. The vertical dimension accommodates multiple iterations, allowing the complete performance timeline to fit within a compact display area while maintaining the relationship between score positions and performance times.
Solution Approach 2:
The time axis is divided into discrete iteration segments that can be independently displayed and scrolled. This segmentation allows users to focus on specific iterations or scroll through different time periods without requiring the entire performance timeline to be visible at once, optimizing the use of display area.

AI summary
A musical score display device and method employing a controller that is configured to control a display to display a musical score and, with the musical score, a first time axis corresponding to a performance of the musical score in which at least one repeat part of the musical score is played during the performance, or a second time axis corresponding to the musical score including at least one repeat sign.
