A device and a method for analyzing an audio datum is described, having a semitone analyzer which is implemented to analyze the audio datum with regard to a volume information distribution over an amount of semitones, and a vector calculator which is implemented to calculate a sum vector over two-dimensional intermediate vectors for each semitone or each element of the definition amount and output an analysis signal based on the sum vector, based on the volume information distribution or a distribution derived from the volume information distribution, which includes a definition amount based on the amount of semitones.
