Chord Touch Regions for Virtual Musical Instrument Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual musical instruments lack tactile feedback and intuitive user interfaces, making it difficult for non-musicians to play pleasing chords and chord progressions, leading to frustration and reduced usability.
Innovation Solution
A user interface with chord touch regions arranged by fifths, featuring treble and bass clef touch zones that allow users to select different chord voicings and bass notes, enabling non-musicians to create sonically pleasing sequences without music theory knowledge, using a touchscreen device with effects and auto-play features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional keyboard interface is simulated on a touchscreen, then the virtual instrument can be played, but non-musicians cannot easily produce pleasing chords and chord progressions due to lack of tactile feedback and music theory knowledge requirements
Solution Approach 1:
The keyboard interface is segmented into chord progressions, with each segment representing a complete chord sequence. Users can select entire chord progressions rather than individual notes, simplifying the interface and making it accessible to non-musicians while maintaining musical functionality.
Solution Approach 2:
Chord progressions are pre-arranged and prepared in advance within the interface. Users can select from pre-composed chord sequences that are already organized in musically pleasing patterns, eliminating the need for users to construct chords themselves and reducing the learning curve.
2Adaptability or versatility
If traditional musical instrument simulation is used, then the instrument can be played, but users without music theory knowledge cannot form pleasing chords and chord progressions
Solution Approach 1:
The system provides self-service functionality by automatically generating and presenting complete chord progressions based on user selections. The interface handles the complex musical theory aspects automatically, allowing users to create pleasing chords without needing to understand or learn music theory concepts themselves.
Solution Approach 2:
The interface is designed to serve both musicians and non-musicians effectively. It provides universal accessibility by offering simplified chord progression selection for beginners while also supporting more advanced users who want to explore complex musical ideas, making the system versatile for different skill levels.

AI summary
A user interface for a virtual musical instrument presents a number of chord touch regions, each corresponding to a chord of a diatonic key. Within each chord region a number of touch zones are provided, including treble clef zones and bass clef zones. Each treble clef touch zone within a region will sound a different chord voicing. Each bass clef touch zone will sound a bass note of the chord. Other user interactions can modify or mute the chords, and vary the bass notes being played together with the chords. A set of related chords and/or a set of rhythmic patterns can be generated based on a selected instrument and a selected style of music.
