Música y lengua de signos a cuatro voces, una experiencia educativa y musical para la inclusión

The binomial sign language and music are gaining more and more presence in our society thanks to the media, social networks and especially YouTube. Only a small number of investigations that deal with the subject in depth. In this article, a qualitative research is presented, through a case study on the Cantatutti Inclusive Choir that signs polyphonic music, to bring people with and without hearing disabilities to the compression of this musical style. The main objective of our research has been to know the incidence that signed polyphonic music in four voices has in the interpreter and in the viewer with and without hearing impairment. After analyzing the results obtained during the process, we can conclude that polyphonic music for a signed choir extends access to culture for deaf people and reinforces the concept visually, for people without hearing impairment.
