A singer-songwriter is a musician who writes, composes, and performs their own musical material, including lyrics and melodies. In the United States, the category is built on the folk-acoustic tradition with a guitar, although this role has transmuted through different eras of popular music. Traditionally, these musicians would write and sing songs personal to them. Singer-songwriters often provide the sole musical accompaniment to an entire song. The piano is also an instrument of choice.
