Set of complex rhythmic tasks exhibiting LRC.

The exponents shown in the table were obtained using DFA and the exponents were computed via the PSD. In the set the complexity of rhythmic drum patterns decreases from tasks no. to . In tasks no. we analyzed real drum recordings that are taken from popular music songs, the two drummers are different persons. Tasks no. were performed by a third (different) drummer, where no. consisted of a short rhythmic pattern (that included beats and off-beats) repeated continuously by the drummer. We analyzed the fluctuations of both beats and off-beats (no. ) of the pattern and in addition we considered the fluctuations of the beats (task no. ) and off-beats (no. ) separately.
