Instrument Profile-Based Pitch Analysis for Musical Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Musical performers lack objective feedback on their instrument-specific tuning and technique issues during performances, relying heavily on third-party feedback and requiring reference performances for assessment.
Innovation Solution
A computer-implemented method and system that identifies an instrument profile associated with the musical instrument, analyzes the pitch of notes based on this profile to determine tuning issues, and generates feedback signals, providing real-time, instrument-specific feedback without the need for comparison to a reference performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If third-party feedback is used to assess musical performance, then performers can obtain external evaluation, but performers lack objective, real-time feedback on instrument-specific tuning and technique issues
Solution Approach 1:
The system implements automatic feedback by analyzing the audio signal from the musical instrument, comparing it against stored instrument profiles containing tuning characteristics, and providing real-time feedback signals to the performer about tuning deviations and technique issues without requiring third-party assessment
Solution Approach 2:
The patent replaces the mechanical system of human third-party assessment with an automated electronic system that uses audio signal processing, digital signal analysis, and computer-based feedback generation to objectively evaluate tuning and technique in real-time
2Adaptability or versatility
If performers require reference performances for assessment, then they can compare their playing, but they cannot efficiently assess freeform performances across various instruments
Solution Approach 1:
The system achieves universality by storing multiple instrument profiles with instrument-specific tuning characteristics and analysis parameters, allowing the same feedback system to adaptively assess various types of musical instruments and performance styles without requiring separate reference performances for each instrument
Solution Approach 2:
The system changes analysis parameters dynamically based on the detected instrument type by selecting appropriate instrument profiles that contain instrument-specific tuning characteristics, enabling efficient assessment of freeform performances across different instruments through parameter adaptation rather than requiring reference performances
3Reliability
If standard musical pieces are required for assessment, then reference performances can be compared, but performers cannot receive feedback on their own freeform playing
Solution Approach 1:
The system enables self-service feedback by automatically analyzing the performer's own playing in real-time, comparing it against instrument profiles, and providing immediate feedback without requiring comparison to external reference performances or standard musical pieces, thus maintaining both objectivity and flexibility

AI summary
Providing feedback on a musical performance performed with a musical instrument. An instrument profile associated with the musical instrument used to perform the musical performance is identified. The instrument profile comprises information relating to one or more tuning characteristics of the instrument. The pitch of notes of the musical performance are analyzed based on the instrument profile to determine a measure of tuning of the musical performance. A feedback signal is generated based on the determined measure of tuning.
