Sound can help people understand visual art.

Experiencing art involves an emotional component, a visceral reaction.  Sound can bring that component to the experience of a work of visual art for a person who is blind or has low vision.

Recordings of audio descriptions are, of course, sound. But combining audio description with sound effects, ambience, music, and sound as analogue can help people with vision loss experience visual art.

For Art Education for the Blind (now Art Beyond Sight), 
I have produced two types of sound recordings: 
(Note: These recordings are designed to be listened to with headphones.)

1. Recordings about specific works of art that use narration, sound effects, and music to    create historical and physical context, or sound analogues to convey visual elements. Here are examples.  You can hear more at American Art.

Louisiana Rice Fields (Thomas Hart Benton) 4:32
Nude Descending a Staircase (Marcel DuChamp) 4:40 
Still Life with Parrots (Jan Davidzon de Heem) 5:38
Number 27 Jackson Pollock) 4:15

2. Recordings that use narration, music, and sound  effects to explain
    the Building Blocks of visual art and the artistic styles of Cubism, Abstraction, and     
    Surrealism. These can be used with both sighted and blind students of art and art history.
