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 (shift), all of which must be done skillfully to avoid noticeable string noise. String may be indicated through Roman numerals (I-IV) or simply the string's base note's letter, fingering may be indicated through numbers for the fingers (1-4), and position may be indicated through ordinal numbers. When two strings are played at the same time it is a double stop.
