Music stand
There are also digital music stands.  When the violinist Tasmin Little played the Ligeti Violin Concerto at a Prom in 2003 she used a special, computerized music stand that had been made for her.  There were no gaps in the music where she could have turned the pages of an ordinary music score.  Instead, the music was on a computer screen, and she moved to the next page by pressing a pedal with her foot.  There was also another pedal for turning back a page which was important to have when practising and for rehearsal.
