usually refers to the storage of a
stringed instrument (i.e. guitar, violin). When resting, a stringed instrument kept within
a case in the playing position may stay in tune more effectively, since its parts will
have less adjusting to do when the instrument is being played.
Guitarists should keep their instruments in a
hard case,
storing it long-ways in the playing position so that the
instrument looks just like it would if it were being held and played.
