Biographies of classical musci composers were examined for family constellation information. Usable data were found for 80 composers. Firstborns, especially only children, were found significantly more frequently than in a sample of creative writers studied by Bliss. Increased frequency of firstborns was also suggested in a study of musical performers by Raychaudhuri. Classical musci composition was seen as an ability more similar to usual academic pursuits than creative writing.
