A method and system for analyzing patterns in the relationships of notes of an input piece of music. The method comprises generating a set of the most frequently occurring note pitches in ascending pitch order that matches an interval pattern, and detecting out-of-key pitches that lie outside of this interval pattern. One or more potential key sequence bifurcations are identified which represent a list of possible key sequences according to forwards and backwards analysis. By finding patterns of repetition in the chordal sequences that may be generated according to these key sequence bifurcations, a key sequence that allows the most frequently recurring chord sequences may be chosen. Chord sequences may be analyzed by using ghost chords, temporary harmonic structures that are created, updated and finalized over time according to a combination of essential and inessential note fragments. The method further comprises identifying non-harmony pitches according to the analyzed chord sequence.

An electronic clock mechanism includes an analog display device including a ring of dates and a stopwatch hand associated with a graduation of a small counter. The ring and hand are driven by a same electric motor via a permanent gear train, the hand being mounted on a wheel of the permanent gear train, the wheel arranged between a motor pinion and a movable element including a date driving wheel. The ring and date driving wheel respectively include two sets of teeth forming a permanent gear having a relatively large clearance to define a dead angle region for the date driving wheel as the ring is positioned by a jumper. The dead angle region is used to drive the stopwatch hand independently of the ring. The permanent gear train is arranged such that torque for positioning the rotor creates for the date driving wheel a blocking torque for shock-resistance.

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.

The present disclosure discloses a method, a client and a computer storage medium for processing information, wherein the method includes: triggering a first operation; downloading a first audio file and a first text file matching the first audio file in response to the first operation; partly truncating the first audio file to obtain a first audio clip according to first indication information for identifying a truncating start position and second indication information for identifying a truncating end position; triggering a second operation; playing the first audio clip and dynamically displaying a text information part in the first text file corresponding to the first audio clip synchronously in response to the second operation; acquiring voice information of a user while playing the first audio chip; and synthesizing the first audio clip and the voice information into a first acquisition result.

A platform or system is disclosed for performing musical analysis to detect musical properties in received live or pre-recorded audio data. The analysis can include a synchronous analysis for generating estimated one or more transitory musical properties and an asynchronous analysis for generating one or more aggregate musical properties which can be applied to the transitory musical properties to generate confirmed musical properties, which can be stored as metadata associated with an audio file. In some cases, live audio data can be received, recorded, dynamically analyzed to provide realtime metadata (e.g., to a display), then the realtime metadata can be analyzed to provide confirmed, updated, or validated metadata. In some cases, initial analysis (e.g., dynamic analysis) can determine chord estimates, usable in further analysis (e.g., offline analysis) to estimate a musical key, which can then be applied to the chord estimates to determine the most likely chord estimates and determine chord progressions.

A display mechanism including a mechanism for fast correction of a position of a display wheel set, an intermediate wheel set ensuring synchronization with an automatic drive mechanism, and, inserted between the intermediate wheel set and the display wheel set, a safety lever driven by the display wheel set during periodic driving thereof, in a trajectory that interferes with a spatial volume of the intermediate wheel set, such that, when the intermediate wheel set is correctly synchronized, the trajectory of the lever does not interfere with the intermediate wheel set, and, when the intermediate wheel set is not correctly synchronized, the trajectory of the safety lever interferes with the intermediate wheel set, which the safety lever then drives in an opposite direction to a single direction of normal operation, to resynchronize the intermediate wheel set.

A music composition, editing, and playback system and method provides a user interface design based on geometric interpretation of music theory replacing traditional modern music notation with geometric shapes including chords represented by polygons that are colored with colors or hues.

Embodiments of the present invention relate to detecting irregularities in audio, such as music. An input signal corresponding to an audio stream is received. The input signal is transformed from a time domain into a frequency domain to generate a plurality of frames that each comprises frequency information for a portion of the input signal. An irregular event in a portion of the input signal corresponding to a set of frames in the plurality of frames is identified based on a comparison of frequency information of the set of frames to the frequency information of other sets of frames of the plurality of frames. This allows an indication of the irregular event to be provided, or for the input signal to be automatically synchronized to a multimedia event.

A system is described that permits identified musical phrases or themes to be synchronized and linked into changing real-world events. The achieved synchronization includes a seamless musical transitionachieved using a timing offset, such as relative advancement of an significant musical onset, that is inserted to align with a pre-existing but identified music signature, beat or timebasebetween potentially disparate pre-identified musical phrases having different emotive themes defined by their respective time signatures, intensities, keys, musical rhythms and/or musical phrasing. The system operates to augment an overall sensory experience of a user in the real world by dynamically changing, re-ordering or repeating and then playing audio themes within the context of what is occurring in the surrounding physical environment, e.g. during different phases of a cardio workout in a step class the music rate and intensity increase during sprint periods and decrease during recovery periods.

A timepiece includes a first member for displaying a local time, a second member for displaying a GMT time, a drive wheel and pinion of the first display member, a first correction mechanism arranged to be able to be kinematically linked to the drive wheel and pinion to allow simultaneous correction of the local time and the GMT time, a second correction mechanism of the second display member, arranged to correct the GMT time independently of the local time, a drive mechanism of the second display member including a differential gear including a first input arranged to be kinematically linked to the drive wheel and pinion of the first display member, a second input arranged to be kinematically linked to the second correction mechanism of the second display member, an output arranged to drive the second display member, and a geartrain mounted in parallel with the drive mechanism.
