SALAMI ObjectivesSALAMI == Structural Analysis of Large amounts of Music InformationMusical analysis has traditionally been conducted by individuals and on a small scaleComputational approach, combined with the huge volume of data now available, will Deliver substantive corpus of musical analyses in common framework for music scholarsand studentsEstablish a methodology and tooling so that community can sustain and enhance this resourcewww.diggingintodata.org
MotivationA resource of this size empowers musicologists to approach their work in a new and different way, starting with the data, and to ask research questions that have not been possible beforeThe analysis is useful in classifying different genres of music and can be used to compare different styles of composition within a composer’s works or between composersIt can also be used to understand historical influences over time and location
