Dedicated Chord Input Unit for Harmony Symbol Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of dedicated input devices for efficiently inputting harmony symbols in musical notation, making the process inconvenient and hindering effective learning and evaluation of harmonics.
Innovation Solution
A harmony symbol input device and method utilizing a dedicated chord input unit, comprising a musical notation provider, a chord input unit provider, and a harmony symbol display part, which allows intuitive input and visualization of harmony symbols through a user-friendly interface with partial key lists, providing real-time feedback and scoring support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a general input device is used for entering harmony symbols, then the device complexity is reduced, but the ease of operation deteriorates due to inconvenient input process
Solution Approach 1:
The input device is segmented into multiple functional units: a musical notation display unit, a dedicated chord input unit with partial key lists, and a harmony symbol display unit. This segmentation allows each component to perform its specific function efficiently, making the overall system easier to operate despite the increased number of components.
Solution Approach 2:
A dedicated chord input unit serving as an intermediary component is introduced between the musical notation display and the harmony symbol display. This intermediary unit provides specialized input controls (partial key lists) that mediate the interaction between the user and the harmony symbol input process, significantly improving ease of operation.
2Productivity
If no dedicated input unit is provided, then the device complexity is minimized, but the productivity deteriorates due to inconvenient input process
Solution Approach 1:
The system performs preliminary action by pre-displaying the musical notation and pre-configuring the partial key lists in the chord input unit before the user begins entering harmony symbols. This preparation enables the user to focus solely on inputting harmony symbols without needing to navigate through complex interfaces, thereby improving productivity.
Solution Approach 2:
The dedicated chord input unit provides self-service functionality by automatically displaying the current harmony section and updating the partial key lists based on the musical notation context. This automatic updating eliminates the need for manual configuration, allowing users to input harmony symbols efficiently without requiring additional setup steps.
3Measurement precision
If harmony symbols are input manually without guidance, then the ease of operation is improved, but the measurement precision deteriorates due to lack of feedback
Solution Approach 1:
The system implements feedback mechanisms in multiple forms: visual feedback through the harmony symbol display unit showing entered symbols, and scoring feedback through the scoring display unit that evaluates the accuracy of harmony symbol input. This feedback loop ensures measurement precision by allowing users to verify their input accuracy while maintaining ease of operation through intuitive display and scoring guidance.

AI summary
Disclosed are a harmony symbol input device and method using a dedicated chord input unit. The harmony symbol input device includes: a musical notation provider configured to visualize and provide a musical notation; a chord input unit provider configured to provide a dedicated chord input unit for inputting a harmony symbol in each harmony section of the musical notation; and a harmony symbol display part configured to repeat an operation that provides highlighting for a specific harmony section in a progression order of the musical notation and displays the harmony symbol received from the dedicated chord input unit in relation to the highlighting.
