Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for learning string instruments, such as guitars or electric bass, do not effectively provide simultaneous indications for rhythmics, notes, and arpeggio execution, nor do they offer anticipatory lighting cues to optimize user learning.
Innovation Solution
A device comprising RGB LED lights arranged in columns and lines corresponding to instrument keys and strings, controlled by a microcontroller to provide synchronized lighting cues for rhythm, notes, and arpeggio execution, with anticipatory lighting sequences to aid learning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LED lights are controlled synchronously with music to be played, then visual feedback for note timing is provided, but the device cannot provide anticipatory cues needed for faster learning
Solution Approach 1:
The patent applies preliminary action by illuminating the target key before the note should be played. The controller illuminates the LED corresponding to the next note position in advance, allowing the learner to prepare and transition smoothly to the correct position, thereby improving learning speed while maintaining accurate timing feedback.
2Loss of information
If LED lights indicate notes to be played, then visual guidance for pitch is provided, but rhythmics and arpeggio execution are not simultaneously indicated
Solution Approach 1:
The patent applies segmentation by dividing the LED control into distinct functional components: note indication (which key to press), rhythmics indication (timing patterns), and arpeggio indication (sequential playing patterns). Each aspect is controlled through specific illumination patterns of the LEDs, allowing comprehensive musical information delivery while managing system complexity through modular control logic.
Solution Approach 2:
The patent applies multi-functionality by using the same LED array to convey multiple types of musical information simultaneously. The LEDs serve not only to indicate which notes to play but also to communicate rhythmics through timing patterns and arpeggio sequences through sequential illumination, eliminating the need for separate indication systems for each musical aspect.
3Speed
If information is provided at the moment of note execution, then real-time feedback is achieved, but user cannot optimize information reception for faster learning
Solution Approach 1:
The patent applies preliminary action by providing visual information before the note execution moment. The controller illuminates the target key in advance of when the note should be played, giving the user time to prepare the correct finger position and movement, thereby optimizing information reception and accelerating learning while maintaining appropriate response timing.

AI summary
The present invention relates to a device to make a musical instrument learning easier, in particular a string instrument such for example a guitar or electric bass, and its respective method of usage. The device is configured to provide at the same time indications relating both to rhythmics and to the notes to be played, as well as to provide indications relating to the execution of arpeggio, and needed to play the various notes in a certain anticipation with respect to the moment in which each note has to be played, and by means of a luminous and chromatic sequence such that the user can optimize the reception of the information and, so, can learn faster.
