As a part of the general human development, musical abilities start to develop before birth and end virtually with death. Every human being has a musical biography containing his or her musical experiences, potentials and activities. Up to the present, research on music abilities and biographies from a lifespan perspective is scarce. This volume presents insights into different aspects of the lifespan development of professional instrumentalists and singers. Ten empirical studies deal with topics like the stages of career development of professional musicians, the development of the singing voice, musical expertise and others. They are of interest for musicians, music teachers, musicologists and other people, who are interested in the developmental psychology of music.
