During this century, a seemingly strengthening trend can be observed in business research-several subfields, including project management, have been'jazzed'. It can be noticed that music and orchestras, particularly jazz, are common metaphors in project, as well as in general and other business fields studies. Another proliferating trend is linking different, ostensibly separated subfields in business research. These initial observations lead to the question: what have the'jazzed'subfields in common, what have they learned and can still learn from jazz (or more broadly, from music), and what can different subfields of business learn from each other? Jazz music approach is a very inclusive, democratic, horizontal, leadership and team-group balanced discipline, using'improvisation'as the main vehicle for problem solving and development of new strategies. In this paper we carry out a literature review, examining what, how, etc. has been'jazzed'so far, concentrating on general organization and project management studies. Next, we analyse the main findings and juxtapose the findings from jazz (or music) with counterparts in project management. In the discussion part we reveal possible developments and possibilities for fostering mutual learning and enrichment and provide suggestions for further advancement.
