Prepared harp
{{Short description|Harp performance}}
Prepared harp is a method of harp performance, similar in concept to prepared piano, in which foreign objects such as pieces of paper are interwoven into the strings to change the tone of the instrument.{{cite book|title=Folk harp journal|url=https://books.google.com/books?id=00UqAQAAIAAJ|accessdate=21 April 2012|date=1 January 2004|page=68}} Among the pioneers of this technique was harpist Anne LeBaron.{{cite book|author=Karin Pendle|title=Women and Music|url=https://books.google.com/books?id=oFZucI550GIC&pg=PA336|accessdate=21 April 2012|year=2001|publisher=Indiana University Press|isbn=978-0-253-21422-5|pages=336–}}
