Methods and apparatus to identify a mood of media

A tangible machine readable storage medium comprising instructions which, when executed, cause a machine to at least:

• access a pre-verbal utterance known to evoke a first emotion;
• create a musical instrument digital interface representation of the pre-verbal utterance;
• synthesize a first synthesized sample based on the musical instrument digital interface representation of the pre-verbal utterance using a digital musical instrument;
• calculate a first value of a first feature of the first synthesized sample;
• create a mood model based on the first value of the first feature, the mood model to correlate the first value of the first feature with the first emotion;
• identify a second value of the first feature of first media evoking an unknown emotion;
• and
• identify the unknown emotion as the first emotion when the mood model indicates that the second value corresponds to the first value.

An apparatus to identify an emotion evoked by media, the apparatus comprising:

• a musical instrument digital interface notator to create a musical instrument digital interface representation of a pre-verbal utterance associated with a first emotion;
• a synthesizer to generate, using a digital musical instrument, a first synthesized sample based on the musical instrumented digital interface representation of the pre-verbal utterance;
• a feature extractor to identify a first value of a first feature of the first synthesized sample, the feature extractor to identify a second value of the first feature of first media evoking an unknown emotion;
• and
• a classification engine to create a mood model based on the first feature, the mood model to establish a relationship between the first value of the first feature and the first emotion, the classification engine to identify the first media as evoking the first emotion when the mood model indicates that the second value corresponds to the first value.
