Why were certain instruments such as the violin used?
In order to preserve the authenticity of the time the original text was written, the musicians referred to descriptions found within the Biblical text to guide the creative process. For example, when they encountered references in the Psalms to violins, psaltery (similar to a harp) and other stringed instruments, the musicians used these or similar instruments in the appropriate song. In other words, they used instruments that most closely fit the period and specifically, the Psalms.
