String change
On string instruments, a string change is a change from playing on one string to another. This may also involve a simultaneous change in fingering and/or position, all of which must be done skillfully to avoid noticeable string noise. String may be indicated through Roman numerals or simply the string's base note's letter, fingering may be indicated through numbers for the fingers, and position may be indicated through ordinal numbers. When two strings are played at the same time it is a double stop.
". Note the string change to A avoided through shifting and the string change to the G string.
