Dynamic Diatonic Instrument Isomorphic Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional musical instruments, including pianos and prior isomorphic grid keyboards, require extensive musical training to play scales and chords in different keys due to their fixed layouts, which limits accessibility and ease of use.
Innovation Solution
A dynamic diatonic instrument with an isomorphic layout of 8x8 multicolor backlit buttons, allowing users to choose between diatonic and chromatic modes, select tonal centers, and change keys and scales easily, enabling the same fingering patterns for major, minor, and diminished chords across all keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed chromatic keyboard layout is used, then the keyboard structure is simple and stable, but different fingering patterns are required for different keys and chord types, increasing the difficulty of operation
Solution Approach 1:
The keyboard layout is made dynamic through software control, allowing the visual indication of notes to change based on the selected key and scale. The physical button positions remain fixed, but their functional assignment and visual feedback adapt dynamically, providing consistent fingering patterns for different keys while maintaining hardware simplicity.
Solution Approach 2:
The system changes the parameter of note assignment to buttons based on the selected key and scale. By dynamically reassigning which notes correspond to which button positions, the keyboard maintains consistent spatial patterns for playing scales and chords across different keys, reducing the cognitive load and fingering complexity.
2Adaptability or versatility
If traditional piano layout with white and black keys is used, then the diatonic scale is clearly distinguished, but extensive musical training is required to play in different keys
Solution Approach 1:
The keyboard buttons serve multiple functions: they can indicate different notes depending on the selected key and scale. The same physical button position can represent different musical notes when transposing between keys, making the instrument universally adaptable to any key while maintaining the same fingering patterns, thus reducing learning difficulty.
Solution Approach 2:
The system provides visual feedback through backlit buttons that change color or illumination patterns to indicate which notes are currently active or should be played. This feedback mechanism guides users in different keys without requiring them to memorize different layouts, enhancing adaptability while easing operation.
3Ease of operation
If isomorphic grid keyboards are used, then chords and scales are easier to play with consistent patterns, but the keyboard is not adaptive to different keys and scales
Solution Approach 1:
The isomorphic grid keyboard is enhanced with dynamic adaptability through software control. The visual indication and note assignment of buttons change dynamically based on the selected key and scale type (major, minor, etc.). This allows the keyboard to maintain its geometric simplicity and consistent fingering patterns while becoming fully adaptive to any musical context.
4Adaptability or versatility
If multiple fixed layout options are provided, then different musical styles can be accommodated, but the device complexity and number of controls increase
Solution Approach 1:
Instead of providing multiple static layout options that would require separate physical controls, the system uses dynamic reassignment of button functions through software. A single physical keyboard can adapt to different musical styles, keys, and scales by changing its note mapping and visual feedback, thereby achieving high versatility without increasing hardware complexity.

AI summary
A musical instrument comprising buttons for playing notes is disclosed, wherein the buttons are arranged in an isomorphic layout consisting of rows and columns, characterized by means for choosing between a diatonic and a chromatic layout of the buttons and by means for choosing between different keys and scales. The buttons can be velocity and/or pressure sensitive, they can be backlit in different colors and they can have a dynamic note information thereon. When the layout is diatonic, the scales are arranged horizontally in rows, the rows being vertically spaced in relative fourths: when the layout is chromatic, the buttons corresponding to the scale notes of the selected key are lit in way different from the other keys.
