Melodic Analysis in David Cope's Experiments in Musical Intelligence

Although David Cope describes Experiments in Musical Intelligence’s (hereafter, EMI) melodic analysis in Schenkerian terms. EMI provides automated, stylistically nondiscriminatory, hierarchical and functional melodic analysis based on the terminal-point destinations, allowing the new compositions resulting from the recombination process to coherently recreate, moment by moment, middle and background structural levels (see Cope, 1996, pages 184-187).

A key point in the melodic analysis process is the concept of signature. David Cope defines signatures (Cope, 1991) as patterns of 1 to 8 contiguous melodic intervals (potentially a larger quantity if including harmonic intervals) that occur in more than one work from the same composer; that is, signatures are style-dependent but work-independent.
