The relationship between pitch-naming ability and childhood onset of music training is well established and thought to reflect both genetic predisposition and music training during a critical period. However, the importance of the amount of practice during this period has not been investigated. In a population sample of twins (N = 1447, 39% male, 367 complete twin pairs) and a sample of 290 professional musicians (51% male), we investigated the role of genes, age of onset of playing music and accumulated childhood practice on pitch-naming ability. A significant correlation between pitch-naming scores for monozygotic (r = .27, p < .001) but not dizygotic twin pairs (r = −.04, p = .63) supported the role of genetic factors. In professional musicians, the amount of practice accumulated between ages 6 and 11 predicted pitch-naming accuracy (p = .025). In twins, age of onset was no longer a significant predictor once practice was considered. Combined, these findings are in line with the notion that pitch-naming ability is associated with both genetic factors and amount of early practice, rather than just age of onset per se. This may reflect a dose–response relation between practice and pitch-naming ability in genetically predisposed individuals. Alternatively, children who excel at pitch-naming may have an increased tendency to practice.

Frederick Douglass may or may not have been the greatest African American abolitionist and orator of the 19th Century, but he was certainly the most accomplished master of self-projection. His autobiographical writings demonstrate the genius with which he seized and manipulated mainstream American symbols and values. By appropriating the Euro-American myth of the self-made man, Douglass guaranteed that his struggle would be canonized, not only within an African American tradition, but within the traditions of the mainstream as well. He manipulated the rhetoric of Anglo-Saxon manhood as skillfully as did any of his white contemporaries, including such master manipulators as Abraham Lincoln, Ralph Waldo Emerson, and Phineas T. Barnum. I mention Douglass along with these wily exemplars of American showmanship, not because I want to drag out embarrassing cliches about making heroes more human, but in order to address the truly monumental nature of Douglass's accomplishments. Douglass, like Lincoln, Emerson, and Barnum, was abundantly endowed with the spiderish craft and foxlike cunning that are often marks of self-made men.
