Progressive Vocal Harmony Audio Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the music field, creating and practicing vocal harmonies can be challenging due to the need for multiple singers to focus on specific notes without distractions, and inexperienced singers may struggle to master harmonies without others, especially when participants are unavailable or have different skill levels.
Innovation Solution
A Music Harmony Tool (MHT) system that uses a computing device to load musical compositions, generate progressive audio presentations, and provide real-time pitch and timing feedback, allowing users to learn and practice vocal harmony parts independently with adjustable volume and visual cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple singers practice vocal harmonies together in person, then they can hear how combined vocal parts sound, but it requires participants to be physically present and available at the same time
Solution Approach 1:
The system creates digital copies of vocal harmony parts as audio recordings. Each singer records their individual harmony part, and the system generates combined audio versions that simulate the sound of multiple singers practicing together. This allows participants to practice harmonies remotely without needing to be physically present at the same time.
Solution Approach 2:
The computing device acts as an intermediary that receives individual vocal recordings, processes them to generate combined audio presentations, and returns these to the singers. This intermediary system enables remote collaboration by automatically creating the combined sound that would otherwise require all singers to be together in a recording studio.
2Ease of operation
If inexperienced singers practice without other singers present, then they can practice independently, but they struggle to master harmonies without hearing combined vocal parts
Solution Approach 1:
The system performs preliminary action by automatically generating combined audio presentations before the singer practices. The computing device creates audio versions with and without the selected harmony part, allowing the inexperienced singer to first hear how their part sounds combined with other parts, then practice independently knowing the expected combined sound.
Solution Approach 2:
The system provides feedback by comparing the singer's individual recording with the generated combined audio versions. This feedback loop allows inexperienced singers to hear how their performance fits into the overall harmony, enabling them to adjust their timing and pitch without needing other singers physically present for real-time feedback.
3Stability of the object's composition
If all vocal harmony parts are played at the same audio volume, then the complete harmony sounds balanced, but the selected harmony part becomes difficult to focus on during learning
Solution Approach 1:
The system applies local quality by selectively adjusting the audio volume of specific harmony parts based on the user's learning needs. When a singer is working on a particular harmony part, the system increases the volume of that specific part while maintaining appropriate volumes for other parts, creating localized audio emphasis that helps with focus without destroying overall harmony balance.

AI summary
Method of teaching a vocal harmony involves a computing device which automatically generates a plurality of audio presentations of a musical composition in a predetermined series. Each audio presentation in the series is different from the other audio presentations in the series and is configured to assist the user in progressively learning the selected vocal harmony part. Each of the plurality of audio presentations in the predetermined series is made different from others of the audio presentation in the predetermined series by selectively controlling (1) the particular ones of the plurality of vocal harmony parts that are included in each of the audio presentations, and/or (2) a magnitude of an audio volume that is applied to each of the plurality of vocal harmony parts that is included in each of the audio presentations.
