Music selection and organization using rhythm, texture and pitch

A method for assigning mood to music, comprising:

• determining a first score corresponding to a rhythm of the music;
• determining a second score corresponding to a texture of the music, wherein determining the second score includes:
• determining an average of frequency densities for the music;
• and
• mapping the average of frequency densities to the second score;
• determining a third score corresponding to a pitch of the music, wherein the first score, the second score and the third score define a rhythm, texture and pitch (RTP) vector for the music;
• comparing the RTP vector to a set of predetermined RTP vectors, wherein each predetermined RTP vector among the set of predetermined RTP vectors is unique and corresponds to only one predetermined mood among a set of predetermined moods;
• and
• assigning a predetermined mood among the set of predetermined moods to the music based on a match between the RTP vector and one of the predetermined RTP vectors among the set of predetermined RTP vectors.

A method for assigning mood to music, comprising:

• determining a first score corresponding to a rhythm of the music;
• determining a second score corresponding to a texture of the music;
• determining a third score corresponding to a pitch of the music, wherein determining a third score includes:
• determining a chromagram for the music;
• determining a chromagram vector for the music from the chromagram;
• comparing the chromagram vector to a set of predetermined chromagram vectors, wherein each predetermined chromagram vector among the set of predetermined chromagram vectors is unique and corresponds to one value of the third score among a set of predetermined values for the third score;
• and
• assigning a value of the third score to the music based on a match between the chromagram vector and one of the predetermined chromagram vectors among the set of predetermined chromagram vectors;
• wherein the first score, the second score and the third score define a rhythm, texture and pitch (RTP) vector for the music;
• comparing the RTP vector to a set of predetermined RTP vectors, wherein each predetermined RTP vector among the set of predetermined RTP vectors is unique and corresponds to only one predetermined mood among a set of predetermined moods;
• and
• assigning a predetermined mood among the set of predetermined moods to the music based on a match between the RTP vector and one of the predetermined RTP vectors among the set of predetermined RTP vectors.

A method for assigning mood to music, comprising:

• determining a first score corresponding to a rhythm of the music wherein the rhythm includes time signatures of the music;
• determining a second score corresponding to a texture of the music, wherein the texture includes frequency densities for the music;
• determining a third score corresponding to a pitch of the music, wherein the first score, the second score and the third score define a rhythm, texture and pitch (RTP) vector for the music;
• comparing the RTP vector to a set of predetermined RTP vectors, wherein each predetermined RTP vector among the set of predetermined RTP vectors is unique and corresponds to only one predetermined mood among a set of predetermined moods;
• and
• assigning a predetermined mood among the set of predetermined moods to the music based on a match between the RTP vector and one of the predetermined RTP vectors among the set of predetermined RTP vectors.

A content selection and organization system, comprising:

• a sampler configured to sample frequency data from a plurality of content and to generate rhythm data, texture data, and static representations based on the sampled frequency data, wherein the content includes music;
• a filter configured to capture intensity differences represented in the static representations and generate pitch data;
• an analyzer configured to generate a first score based on the rhythm data, wherein the rhythm data includes time signatures of the music, a second score based on the texture data, wherein the texture data includes frequency densities for the music, and a third score based on the pitch data, wherein the first score, the second score and the third score define a rhythm, texture and pitch (RTP) vector for the music, wherein the analyzer is further configured to compare the RTP vector to a set of predetermined RTP vectors, wherein each predetermined RTP vector among the set of predetermined RTP vectors is unique and corresponds to only one predetermined mood among a set of predetermined moods;
• and wherein the analyzer is further configured to assign a predetermined mood among the set of predetermined moods to the content based on a match between the RTP vector and one of the predetermined RTP vectors among the set of predetermined RTP vectors;
• and
• a user interface configured to enable a user to view and to select content from the plurality of content based on the assigned predetermined moods.
