Constantinescu stands out among the composers who followed George Enescu into the Romanian musical limelight during the first half of the 20th century. On the one hand, through his diverse oeuvre, which encompasses almost all of the genres from chamber music to film music, and on the other hand, through his own musical language, consisting of great color and harmonic variety. Skilfully adapted ecclesiastic Byzantine modes and chants, modal scales, and the authentic and fascinating melodies of Romanian folk music merge within Constantinescu's oeuvre, which stands balanced somewhere between Western tradition and a national musical idiom.
