Real time music recognition and display system

A computerized method for providing a music tutor, the method comprising:

• training a system to recognize a set of notes played by a musical instrument from one or more reference notes played by the same musical instrument;
• retrieving a set of musical data comprising one or more reference notes;
• displaying at least a portion of the set of musical data, said portion including a current note from the one or more reference notes;
• receiving a played note;
• comparing the played note to the current note;
• and
• displaying an indication of whether the played note matches the current note.

A computerized system comprising:

• a processor and a memory coupled to the processor;
• an analog to digital (A/D) converter coupled to the processor;
• a sound input device coupled to the A/D converter;
• a database;
• and
• a display;
• wherein the analog to digital converter is operable to receive sound input from the sound input device and wherein the processor is operable to:
• receive a set of data from the A/D converter, said data representing at least one note,
• extract note features from the set of data,
• applying a weighting to at least a subset of the note features, and
• identify the note based on matching the data representing at least one note to the set of database data, said identification occurring in near real-time, wherein a match occurs when at least a subset of the extracted features match a note in the dataset of saved note features.

A computer-readable medium having computer-executable instructions for performing a method for recognizing music, the method comprising:

• receiving an input data representing a played note;
• performing time alignment on the input data;
• extracting features from the input data;
• weighting at least a subset of the features;
• and
• comparing according to the weighting the extracted features to a dataset of saved note features to determine a matching note;
• wherein a match occurs when at least a subset of the extracted features match a note in the dataset of saved note features.

A computer-readable medium having computer-executable instructions for performing a method for providing a music tutor, the method comprising:

• training a system to recognize a set of notes played by a musical instrument to create one or more reference notes played by the same musical instrument;
• retrieving a set of musical data comprising one or more reference notes;
• displaying at least a portion of the set of musical data, said portion including a current note from the one or more reference notes;
• receiving a played note;
• comparing the played note to the current note;
• and
• displaying an indication of whether the played note matches the current note.

A computerized system comprising:

• a database having a set of data representing at least one database note;
• a sound input interface;
• a pattern matching module coupled to the database and the sound input interface and operable to compare a set of data representing at least one played note with the set of data representing the at least one musical note and to identify the played note, the identification comprising applying a weighting to at least a subset of a set of note features in the set of data and performing a comparison of the weighted set of note features of the at least one played note to the set of data representing the at least one musical note;
• a compose segment module operable to receive the identified played note and to output the played note.
