With the possible exception of the guitar in contemporary popular music, the piano has proven itself the most popular Western musical instrument. For decades during the later nineteenth and most of the twentieth centuries, almost every upper- and middle-class European and American family owned one. Furthermore, the piano possesses a larger and more variegated repertory than even the violin. In addition to their concerts and recorded legacies, two pianists—Leslie Howard and the late Charles Rosen—have contributed to musical scholarship. A third performer, Garrick Ohlsson, speaks about his own pianistic preferences without an interviewer’s queries and prompts.
