A musical instrument with novel configurations and performance techniques that can play notes and scale tones is disclosed. The musical instrument implements design and ergonomic changes to a Theremin's traditional configuration and use. The musical instrument includes an additional sound generation device such as an actuator that is operated to provide rhythm and tonal results. The musical instrument includes a pitch antenna that is configured in a horizontal position, which creates a different plane of reference with respect to performance motions employed for modifying the pitch. The musical instrument allows for a user to play notes and scale tones in a standing, seated, or ambulatory position. Improved playing interfaces, accessory items, and other characteristics for enhancing the playing of the musical instrument are provided.

This invention relates to the field of music education technology, specifically to a musical instrument playing training system and method based on real-time pitch monitoring. The system includes a musical instrument acoustic waveform analysis module, a tuning frequency tracking module, a pitch deviation analysis module, a muscle memory reshaping guidance module, and a musical instrument mastery blind spot positioning module. In this invention, by sensing the vibration envelope and reconstructing the energy distribution of the overtone series, the core musical tone components are accurately extracted from a complex acoustic environment, improving the accuracy of fundamental frequency identification and enhancing the ability to capture microscopic pitch drift. This effectively solves the problem of poor anti-interference in traditional detection methods, transforming pitch deviation into a concrete physiological cause analysis, optimizing the depth of performance mechanism analysis and enhancing the physical correction directionality. It achieves precise integration of correction actions and performance rhythm, ensuring the scientific nature of muscle memory reshaping and significantly reducing functional pitch deviation. By tracking the rate of movement deformation and tracing the source of technical bottlenecks, it optimizes musical instrument mastery and improves the level of intelligent music training.

The application provides a music rhythm display method and device, a storage medium and an electronic device, and belongs to the field of audio signal processing. In the application, whether a beatmap of music has been created is determined when music is detected to be played; and when it is determined that the beatmap of music has been created, a current audio frame of the music and a historical beatmap are obtained, and then the historical beatmap can be updated based on the current audio frame to obtain a current beatmap, and the current beatmap is displayed. In the application, the historical beatmap can be updated according to the current audio frame when the music is played to obtain and display the current beatmap, and thus the beatmap does not need to be redrawn every time, time and effort are saved, the problem of time and effort consumption caused by multiple drawings is solved, and memory expenditure is effectively saved.

This invention relates to the field of audio signal processing technology, and in particular to an automatic harmony generation method and system based on multi-dimensional feature matching. By introducing a context-aware mechanism and streaming iterative optimization, it achieves a leap from static feature matching to dynamic music semantic understanding and generation. It not only extracts basic features such as pitch and rhythm in real time, but also integrates high-level contextual information such as harmonic tension trends, musical form positions, and emotional energy, so that the generated harmony can fit the overall development and emotional flow of the music. Through the collaboration of the harmony decision fusion model and the streaming iterative optimizer, the system can continuously make dynamic adjustments and smooth corrections based on real-time input and user feedback during the performance. This significantly improves the system's real-time interactivity, melody following, and creative expressiveness while ensuring the rationality of the harmonic music, and can effectively meet the intelligent harmony assistance needs in highly dynamic scenarios such as improvisation and interactive music generation.
