Accompaniment Music Key Adjustment for Narrow Vocal Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing karaoke systems struggle to accommodate singers with narrow vocal ranges, as they often cannot sing songs that require a wide vocal range, even after musical key transposition, due to inconsistent key adjustments and inaccurate pitch predictions during live singing.
Innovation Solution
A method to adjust accompaniment music by transposing different sections of a song to match the singer's vocal range, allowing for varying musical key changes across the song to ensure the singer can perform all notes within their range, using an electronic device with a processor and memory to analyze and adjust the musical keys of multiple sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the musical key of the whole song is consistently transposed to accommodate a singer's vocal range, then the singer can sing some notes within their range, but other notes outside the transposed range remain unsingable
Solution Approach 1:
The song is divided into multiple sections (e.g., verse, chorus, bridge), and each section is transposed independently to different keys based on the vocal requirements of that specific section. This allows the accompaniment music to adapt to the singer's vocal range in each segment while maintaining overall song integrity.
Solution Approach 2:
Different sections of the song are assigned different musical keys tailored to the specific vocal demands of each section. High-note sections are transposed to lower keys, low-note sections to higher keys, ensuring optimal singability throughout the entire song rather than applying a uniform transposition.
2Force
If the musical key is transposed in advance to match the singer's vocal range, then the singer can sing prepared sections, but live singing requires quick responses that make real-time transposition difficult
Solution Approach 1:
The system pre-calculates and prepares multiple transposed versions of the accompaniment music for different sections of the song before the performance. When the singer begins singing, the system automatically detects the vocal range and selects the appropriate pre-prepared transposed sections, eliminating the need for real-time manual transposition while maintaining quick response capability.
3Measurement precision
If the song is transposed downward by one or two semitones to help singers with narrow vocal ranges, then high notes become singable, but low notes become unsingable
Solution Approach 1:
The system dynamically adjusts the musical key of different sections based on the singer's actual vocal performance and detected range. Instead of a static downward transposition, the system applies variable transposition amounts to different sections, raising keys for low-note sections and lowering keys for high-note sections, thereby maintaining vocal range flexibility throughout the song.

AI summary
A method for adjusting accompaniment music is disclosed. The method transposes the musical key of at least one section of the accompaniment music such that a song will have different musical key transpositions for different sections of the accompaniment music, so that singers whose vocal ranges are narrow can sing songs after the adjustment.
