“…A general proclivity to play sharp is substantiated by much research-based evidence (e.g., Geringer, 1978;Geringer & Witt, 1985;Madsen, Edmonson, & Madsen, 1969 ;Morrison, 2000;Salzberg, 1980;Yarbrough, Morrison, & Karrick, 1997); by a tendency to discriminate flat pitch better than sharp pitch (Dunnigan & Geringer, 2002;Geringer & Witt, 1985;Wapnick & Freeman, 1980); and by octave stretch, a general tendency to hear a 2:1 ratio octave interval as too small (e.g., Burns, 1974;Demany & Semal, 1988;Hartmann, 1993). Notably, however, comparisons between perception and performance, that is, between judging intonation and "doing" it, have not shown significant relationships (in instrumental settings, see Ely, 1992;Geringer & Witt, 1985;Yarbrough, Karrick, & Morrison, 1995;Yarbrough et al, 1997).…”
