Huapanguera
The huapanguera, guitarra quinta huapanguera or guitarra huapanguera is a Mexican guitar-like instrument that usually forms part of a conjunto huasteco ensemble, along with the jarana huasteca and violin. Because of its large body and deeper structure, the huapanguera is able provide a much deeper sound compared to a regular acoustic guitar. Here it takes on the role of the bass instrument using a rhythmical strumming technique. Its physical construction features a large resonating body with a short neck. It normally has around 10 frets which stop at the point where the fingerboard meets the top.
