Text Providing Device for Chord Progression Explanation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users without a certain degree of knowledge in music theory struggle to understand chord progressions in music, as existing techniques rely on image information like arrow symbols and colors, which are not intuitive for non-experts.
Innovation Solution
A text providing method and device that generates explanatory text based on chord input data, using a trained model to convert chronological chord sequences into descriptive text, leveraging neural networks like RNN and Seq2Seq for effective handling of time-series data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If image information such as arrow symbols and colors is used to represent chord progressions, then the visual representation is improved, but the understandability for users without music theory knowledge deteriorates
Solution Approach 1:
The patent introduces explanatory text as an intermediary element between the chord progression data and the user. The text providing device generates human-readable explanations that bridge the gap between technical music theory concepts and general user understanding, making the information accessible without requiring prior music theory knowledge
Solution Approach 2:
The patent changes the representation parameter from symbolic/graphical (arrows, colors) to textual description. By transforming the chord progression information into natural language explanations, the system makes the content more accessible to users without specialized knowledge while maintaining the essential musical information
2Measurement precision
If detailed music theory analysis is provided, then the accuracy of chord progression explanation is improved, but the accessibility to general users deteriorates
Solution Approach 1:
The patent applies local quality by providing music theory-based analysis only where necessary and translating it into simple terms. The system maintains analytical accuracy for cadence detection while presenting the information in an accessible manner, adapting the depth of explanation to the user's needs without requiring specialized knowledge
Solution Approach 2:
The explanatory text serves as a mediator that preserves the accuracy of music theory analysis while making it accessible to general users. The text providing device translates technical analysis into natural language, maintaining precision in chord progression understanding while removing barriers to accessibility
Data Source
AI summary
In an embodiment, a text providing method includes providing chord input data, in which chords are aligned in chronological order, to a trained model in which a relationship between chord sequence data, in which chords are aligned in chronological order, and explanatory text related to the chords included in the chord sequence data is learned, and obtaining text corresponding to the chord input data from the trained model.
