Real-time jamming assistance for groups of musicians

The method of claim 41, wherein:

• the self-similarity is calculated using analysing of the received real-time audio signal so as to extract an internal representation for the played music;
• and
• the internal representation comprises:
• a sequence of feature vectors that represent the musical contents of a short segments of received audio signal;
• or
• a sequence of high-level descriptors of the received audio signal, wherein the high-level descriptors comprise any one or more of chords;
• notes;
• and drum sound notes.

A method comprising

• automatically tracking beat of the played music from the real-time audio signal and accordingly automatically predicting a time of a next beat;
• automatically recognising from the real-time audio signal at least one of chords;
• notes;
• and drum sounds and accordingly automatically detecting repetitions in the played music
• automatically predicting a next development in the played music, based on the detected repetitions, comprising at least one of chords;
• notes;
• and drum sounds that will be played next, and respective timing based on the predicted time of the next beat;
• and
• automatically producing a real-time output based on the predicted next development in the played music;
• wherein a pre-defined library of musical patterns is used to assist in the predicting of the next development in the played music.

An apparatus comprising a processor and computer program code configured to cause the apparatus to automatically perform, on executing by the processor of the computer program code:

• receiving a real-time audio signal of played music that is played by at least one person;
• tracking beat of the played music from the real-time audio signal and accordingly predicting a time of next beat;
• recognising from the real-time audio signal at least one of chords;
• notes;
• and drum sounds and accordingly detecting repetitions in the played music;
• predicting a next development in the played music, based on the detected repetitions, comprising at least one of chords;
• notes;
• and drum sounds that will be played next, and respective timing based on the predicted time of the next beat;
• and
• producing a real-time output based on the predicted next development in the played music;
• wherein the processor and computer program code are configured to cause the apparatus to perform, on executing by the processor, the predicting of the at least one of:
• chords;
• notes;
• and drum sounds by detecting self-similarity in the played music.

• and
• producing a real-time output based on the predicted next development in the played music;
• wherein the processor and computer program code are configured to cause the apparatus to use a pre-defined library of musical patterns to assist in the predicting of the next development in the played music.
