One embodiment provides a system, method, and device for utilizing inaudible tones for music. A song is initiated with enhanced features. A determination is made whether inaudible tones including information or data are associated with a portion of the song. The associated inaudible tone is played. Playback of the song is continued.

Methods are provided for enabling audience members at a live or substantially live performance to interact with performers and participate in the performance.

The present disclosure provides a system for dynamic, real-time composition of sheet music including: a data library including a plurality of static music notation files, each static music notation file represented as divided into a plurality of blocks; a primary device in communication with the data library, the primary device including a user interface, memory storing program instructions, and a communications module; a receiver device in communication with the primary device; wherein, in response to executing the instructions, the primary device: communicates a dynamic notation file to the receiver device based on a configuration of the plurality of blocks arranged by the primary device; and presents a GUI including controls for moving selections of one or more of the plurality of blocks in real-time while the communication to the receiver device is in progress.

An integrated system and method that provides users with non-destructive ways of manipulating musical scores and or audio recordings for student practise, testing and assessment. The said integrated system and method allows users to create questions that utilise one or more of the manipulated items, present questions to a student, collect the said students answer and assess the said students answer. The said integrated system is delivered via digital devices including computers, tablets, smartphones and other such devices.

A singing voice edit assistant method includes: displaying singing waveforms represented by singing waveform data calculated based on score data representing a time series of notes and lyrics data representing words on a display device, on a note-by-note basis on a two-dimensional waveform screen having a pitch axis and a time axis, each singing waveform being displayed at a position located by a pitch and timing of a note corresponding to the singing waveform; and displaying a phoneme of each word at a pronunciation timing of the phoneme on the waveform screen.

Musical score acquisition section acquires musical score information representing a musical score of a music piece to be practiced by a user. Target portion setting section sets a plurality of portions of the music piece as target portions for training, respectively. Target musical score acquisition section acquires target musical score information indicative of partial musical scores of the respective target portions for training set by the target portion setting section. Display control section controls, on the basis of the target musical score information acquired by the target musical score acquisition section, a display device to display two or more of target musical scores in a side-by-side arrangement. Thus, a user can easily grasp the plurality of target portions for training.

The present invention relates to a polypeptide having protease activity comprising a zinc finger protease domain, a helix-turn-helix domain and a GAF domain. The core protein sequence of the protease is shown as SEQ ID NO: 1. The invention also relates to optimized reaction conditions for the protease and methods of increasing the protease activity.

An automatic performance system includes a sign detector configured to detect a sign action of a performer performing a musical piece, a performance analyzer configured to sequentially estimates a performance position in the musical piece by analyzing an acoustic signal representing performed sound in parallel with the performance, and a performance controller configured to control an automatic performance device to carry out an automatic performance of the musical piece so that the automatic performance is synchronized with the sign action detected by the sign detector and a progress of the performance position estimated by the performance analyzer.

An electronic musical score apparatus 1 includes display units D1, D2 connected to each other to be openable and closeable, and can convert a writing made on display portions 11, 12 by a user into annotation data 1, associated with musical score page data but being manageable separately from the musical score page data, and store the annotation data 1. When an image of the associated musical score page data is displayed together with an image of the annotation data 1 on the display portions 11, 12 and then the user rewrites the annotation data 1, the electronic musical score apparatus 1 can provide a write history for the annotation data 1 by storing the annotation data 1 before the rewriting as first-generation annotation data 1 and storing the annotation data 1 after the rewriting as second-generation annotation data 1.

Systems and methods for re-arranging a musical composition using augmented reality are disclosed. A user can be provided with one or more physical image markers representative of at least one of a musical entity and a musical style in which a musical track has been pre-recorded. Upon capturing a visual scene in which one or more of these physical image markers are included, an augmented reality version of the visual scene is displayed along with audio corresponding to the musical style(s) and/or entities represented by the one or more physical image markers.
