20080289480 | ELECTRONIC KEYBOARD MUSICAL INSTRUMENT FOR ASSISTING IN IMPROVISATION - A musical keyboard includes a plurality of white keys and black keys. As a number of keys are depressed simultaneously, a pattern of the depressed keys is judged as categorized in a number of predetermined patterns of depressed keys in view of the white keys and the black keys based on the input note data acquired from the depressed keys. A plurality of types of harmonization are predetermined, from among which a type of harmonization is determined. According to the determined type of harmonization, the input note data representing the notes of the depressed keys are adjusted so that inadequate notes included in the input notes are changed to adequate notes to constitute a chord as permitted by the type of harmonization in view of musical grammar. An unskilled player can play music incorporating improvisation which would need higher musical skill, as the inadvertently erroneous depression of the keys is rectified in the note data processing. | 11-27-2008 |

Provided herein is a method, computer program product and electronic device for assigning a set of pitches to a plurality of cells of an electronic device having a touch screen input device. The method may include the steps of obtaining an input chord, disassembling the chord into at least one base note and a plurality of individual voices, arranging a predetermined number of voices of the chord according to at least one predefined rule, and assigning at least one set of pitches to a plurality of cells of an electronic device, said set of pitches corresponding to the base note and arranged predetermined number of voices of the chord. The present method allows a musician to freely play along without the possibility of playing an errant note as the user does not control the actual pitch associated with the cells being indicated by a user on the touch screen. | 05-19-2016 |
20160148604 | AUTOMATIC COMPOSITION APPARATUS, AUTOMATIC COMPOSITION METHOD AND STORAGE MEDIUM - An automatic composition apparatus includes a processing unit. The processing unit performs (i) a calculation process of calculating a matching level of each chord progression data item for a motif including a plurality of note data items, with reference to a plurality of note connection rules each of which defines a connection relation of consecutive note types, and (ii) a melody generating process of generating a melody based on the motif and the chord progression data items which matching levels are calculated. | 05-26-2016 |
20160379611 | Systems and Method for Music Remixing - Systems and methods for creating, modifying, interacting with and playing music are provided, preferably employing a top-down process, where the user is provided with a musical composition that may be modified and interacted with and played and/or stored (for later play). The system preferably is provided in a handheld form factor, and a graphical display is provided to display status information, graphical representations of musical lanes or components which preferably vary in shape as musical parameters and the like are changed for particular instruments or musical components such as a microphone input or audio samples. An interactive auto-composition process preferably employs musical rules and a pseudo random number generator, which may also incorporate randomness introduced by timing of user input or the like. The user may quickly begin creating desirable music in accordance with one or a variety of musical styles, with the user modifying the auto-composed (or previously created) musical composition, either for a real time performance and/or for storing and subsequent playback. An analysis process flow also is disclosed for using pre-existing music as input(s) to an algorithm to derive music rules that may be used as part of a music style in a subsequent auto-composition process. In addition, the present invention makes use of node-based music generation as part of a system and method to broadcast and receive music data files, which are then used to generate and play music. By incorporating the music generation process into a node/subscriber unit, bandwidth requirements are lowered, and consequently the bandwidth can preferably be used for additional features such as node-to-node and node-to-base music data transmission. The present invention is characterized by the broadcast of relatively small data files that contain various parameters sufficient to describe the music to the node/subscriber music generator. In addition, improved audio synthesis in a portable environment is provided with the present invention by performing audio synthesis in a manner that simplifies design requirements and/or minimizes cost, while still providing quality audio synthesis features targeted for a portable system (e.g., portable telephone). In addition, problems associated with the tradeoff between overall sound quality and memory requirements in a MIDI sound bank are addressed in the present invention by providing systems and methods for a reduced memory size footprint MIDI sound bank. In addition, music ringtone alert tone remixing, navigation, and purchasing capabilities are disclosed that are particularly advantageous in the context of a portable communications device, such as a cellular telephone, in connection with a communications network. | 12-29-2016 |
