Abstract: A method for following a musical score in real time. At least one sound emitted by a performer is recorded. At least one chromatic vector is estimated. The chromatic vector is compared with theoretical chromatic vectors of the musical score. A transition between the chromatic vector and a previous chromatic vector with theoretical transitions of the musical score is compared. A work position of the performer depending on a previous work position is estimated from the comparison of the chromatic vector and the comparison of the transition. The recording is carried out for a suitable period depending on the ratio between a period of the transition and a reference period.

Abstract: A method of providing synchronized content to a user including: (i) an audio recording of a voice reading written language text and an audio recording of one or more pieces of music; (ii) written language text and music notation content, having elements that can be identified, displayed, and highlighted, the elements representing discrete segments of the written language and music notation content, each of the discrete segments having a beginning and end; and (iii) synchronization data marking beginning and end points in the audio recordings for each element. The method is implemented such that a user may play the audio recording of a voice reading the written language text, and the audio recording of the one or more pieces of music according to the EPUB format, and display the written language text and music notation content according to the EPUB format with synchronization.

Abstract: An apparatus for synchronized digital sheet music display and audio playback comprises an electronic appliance. The apparatus includes an audio output for playing an audio recording of a piece of music and a display for displaying the piece of music in notation form, including a first portion thereof and comprising elements representing discrete segments of the piece of music that may be identified, displayed, and highlighted. The apparatus further comprises software for controllably playing the recording of and displaying the piece of music, highlighting a second portion of the piece of music within and advancing through the first, and synchronizing the highlighted second portion with the audio played from the audio output.
