Ground bow

The ground-bow, also known as an earth-bow or ground harp,[1] is a single-string bow-shaped folk musical instrument, classified as a chordophone.

In their language "galinga" means simply a hole in the ground, while the origins of "kalinga" are uncertain.

[10][11] Julio Cueva's song Tingo Talango dedicated to this musical instrument describes its construction thus:Si quieren que les describa cómo es el tingo talango tráiganme un gajo de güira o si no uno de mango.

Se abre un hueco en el suelo, encima una hoja de lata, en el centro un agujero donde un alambre se ata.

It can be played in a glissando manner: the stick is bent, struck, and released, producing a peculiar sound.
