(2) We want to graphically show correlations between the length of notes and their heights using a piece coded in musicxml or humdrum format (these are from our downloaded corpora):

for work in ['opus18no1', 'opus59no3']:
    movementNumber = 3
    score = corpus.parseWork(work, movementNumber)
    
    for part in score:
        instrumentName = part.getElementsByClass(instrument.Instrument)[0].findName()
        grapher = correlate.NoteAnalysis(part.flat.sorted)    
        grapher.pitchToLengthScatter(title='%s, Movement %s, %s' % (work, movementNumber, instrumentName))
