Which of these instruments is traditionally not associated with Appalachian music?

The piano is traditionally not associated with Appalachian music. Appalachian music, which encompasses a rich variety of folk styles, typically features instruments that have deep roots in the musical traditions of the region, such as the banjo, autoharp, and dobro.

The banjo has roots in African American music and became a central instrument in Appalachian folk music due to its distinctive sound and versatility. The autoharp, with its unique chord-playing capability, is often used in folk contexts, providing rhythmic and harmonic support. The dobro, a type of resonator guitar, adds a particular twang and sound that complements the vocal styles prevalent in Appalachian music.

In contrast, while the piano can certainly be found in various music genres, it is not traditionally linked to the acoustically driven and often outdoor nature of Appalachian music. Thus, it stands apart from the instruments that are characteristically used to create the distinctive sounds of this regional music.
