Electronic Musical Keyboard Control for Stable Lyric Syllable Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic musical instruments require complex user operations to control the progression of lyrics and synthetic voice, making it difficult to generate lyrics easily.
Innovation Solution
An electronic musical instrument with a keyboard configuration that includes separate key ranges for controlling syllable position, where syllable advancement is controlled by specific key operations, allowing continuous maintenance of one key range to stabilize syllable position and advancement with another range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dedicated controllers are used to manipulate phrase progress, then precise control of lyrics progression is achieved, but user operations become complex
Solution Approach 1:
The keyboard is designed to serve dual functions: it can play musical notes in the first pitch range and control lyrics progression in the second pitch range. This eliminates the need for dedicated controllers while maintaining precise control capability, as the same keyboard can manipulate both music and lyrics progression through different key ranges.
Solution Approach 2:
The keyboard is divided into two distinct pitch ranges with different functions. The first pitch range (lower keys) is dedicated to musical note playing, while the second pitch range (higher keys) is dedicated to lyrics progression control. This segmentation allows each key range to be optimized for its specific function while using a single unified interface.
2Productivity
If the syllable position advances with each key operation in the second pitch range, then lyrics progression is achieved, but continuous musical playing in the first pitch range is disrupted
Solution Approach 1:
The system dynamically adjusts the syllable position based on the state of key operations. When a key in the first pitch range is being continuously maintained (musical playing), the syllable position is held stable. When no keys in the first pitch range are pressed, the syllable position advances with key operations in the second pitch range. This dynamic behavior allows the system to adapt to different playing contexts.
Solution Approach 2:
The control behavior changes based on the parameter of which pitch range is currently active. The system monitors whether keys in the first pitch range are being pressed and adjusts the syllable position advancement behavior accordingly. This parameter-based control allows seamless switching between music playing mode and lyrics progression mode.

AI summary
An electronic musical instrument includes: a plurality of keys that include at least first keys corresponding to a first pitch range and second keys corresponding to a second pitch range; and at least one processor, configured to perform the following: causing a syllable position in a phrase that is digitally synthesized for output not to be advanced no matter how the second keys in the second pitch range are operated while a key operation in the first pitch range is being continuously maintained; and causing the syllable position to advance every time a key operation in the second pitch range is performed while none of the first keys in the first pitch range is being operated.
