Performance content synchronization based on audio

A music creation apparatus for creating a musical work based on combination of a plurality of performance content items, the performance content items, including first, second, third, and fourth performance content items, each containing at least audio data, the music creation apparatus comprising:

• a memory;
• and
• a processor configured to implement instructions stored in the memory and execute a plurality of tasks, including:
• a displaying task that displays, on a display device, a music creation screen displaying a plurality of blocks, including first, second, third, and fourth blocks, arranged in a matrix arrangement for displaying the plurality of performance content items constituting the musical work, the first, second, third, and fourth blocks being designatable to reproduce at least an audio from the first, second, third, and fourth performance content items, respectively;
• and
• a reproducing task that, in response to a single reproduction instruction given by the user, reproduces at least the audios based on the performance content items associated with the plurality of blocks,
• wherein the reproducing task simultaneously plays at least first and second audios associated with at least the first and second performance content items of at least the first and second blocks arranged in one of one row or column, without playing at least third and fourth audios associated with at least the third and fourth content items of at least the third and fourth blocks arranged in one of another row or column, and thereafter, without playing the at least the first and second audios, sequentially plays at least the third and fourth audios associated with the at least the third and fourth performance content items of the at least the third and fourth blocks arranged in the one of another row or column, respectively after playing of the at least the first and second audios ends, the at least the third and fourth audios, when played, also being simultaneously played together.

A non-transitory computer-readable storage medium storing instructions executable by a computer to perform a method of creating a musical work based on combination of a plurality of performance content items, including first, second, third, and fourth performance content items, each containing at least audio data, the method comprising:

• a displaying step of displaying, on a display device, a music creation screen displaying a plurality of blocks, including first, second, third, and fourth blocks, arranged in a matrix arrangement for displaying the plurality of performance content items constituting the musical work, the first, second, third, and fourth blocks being designatable to reproduce at least an audio from the first, second, third, and fourth performance content items, respectively;
• and
• a reproducing step of, in response to a single reproduction instruction given by the user, reproducing at least the audios based on the performance content items associated with the plurality of blocks,
• wherein the reproducing step simultaneously plays at least first and second audios associated with at least the first and second performance content items of at least the first and second blocks arranged in one of one row or column, without playing at least third and fourth audios associated with at least the third and fourth content items of at least the third and fourth blocks arranged in one of another row or column, and thereafter, without playing the at least the first and second audios, sequentially playing at least the third and fourth audios associated with the at least the third and fourth performance content items of the at least the third and fourth blocks arranged in the one of another row or column, respectively after playing of the at least the first and second audios ends, the at least the third and fourth audios, when played, also being simultaneously played together.

A music creation system for creating a musical work based on combination of a plurality of performance content items, including first, second, third, and fourth performance content items, each containing at least audio data, the music creation system comprising:

• a server including a database storing the plurality of performance content items constituting a musical work;
• and
• a client terminal communicable with the server via a network and comprising:
• a memory;
• and
• a processor configured to implement instructions stored in the memory and execute a plurality of tasks, including:
• a content item-acquiring task that acquires from the database of the server, the plurality of performance content items constituting the musical work;
• a displaying task that displays, on a display device, a music creation screen displaying a plurality of blocks, including first, second, third, and fourth blocks, arranged in a matrix arrangement for displaying the plurality of performance content items constituting the musical work, the first, second, third, and fourth blocks being designatable to reproduce at least an audio from the first, second, third, and fourth performance content items, respectively;
• and
• a reproducing task that, in response to a single reproduction instruction given by the user, reproduces at least the audios based on the performance content items associated with the plurality of blocks,
• wherein the reproducing task simultaneously plays at least first and second audios associated with at least the first and second performance content items of at least the first and second blocks arranged in one of one row or column, without playing at least third and fourth audios associated with at least the third and fourth content items of at least the third and fourth blocks arranged in one of another row or column, and thereafter, without playing the at least the first and second audios, sequentially plays at least the third and fourth audios associated with the at least the third and fourth performance content items of the at least the third and fourth blocks arranged in the one of another row or column, respectively after playing of the at least the first and second audios ends, the at least the third and fourth audios, when played, also being simultaneously played together.
