Musicology defines the style mainly on the basis of the compositional features; the use of tools for the analysis of the sound signal to study the expressive features in argentine popular music is recently applied. We propose that the musical phrasing in tango performers could focus on the recurrent characteristics of temporal elongation and shortening of rhythmic-melodic patterns embedded in the musical structure. Thus the stylistic identity would be the result of the interaction between the musical properties and the microtiming of such patterns. In this work, we combine musical analysis and temporal microanalysis to examine the individual and joint temporal variability, comparing in the same arrangement, the phrasing of Aníbal Troilo's orchestra with other current orchestras.
