Singer-songwriter
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. Singer-songwriters often provide the sole musical accompaniment to an entire song. The piano is also an instrument of choice.
In the early 21st century, various digital production tools, examples including GarageBand and other software programs, began to be used by singer-songwriters to compose their music and otherwise work as an audio engineer enhancing media.
