When i first began learning the violin in Grade school a violin teacher told me that when I am not playing and the violin is in its case to keep the violin strings tight and tuned.  But yet another teacher told me to loosen the strings when I am not playing. Still yet a third teacher told me to keep the strings tuned and tight even when i am not playing however, to loosen the strings if and when I am storing the violin for a prolonged period (say a few weeks) without playing.  Over the years I have heard all sorts of conflicting advice.

From my own experience I have found that storing with the strings tight and tuned has never caused any problems. On the other hand frequent loosening and tightening of the strings seems to cause much more frequent string breakage.   So, out of my own experience I tend to keep my strings tight and tuned, even when the violin is stored for a week or more..

Is there any official consensus on this among violin players ? Should I be loosening the strings if I plan to store thhe violin without playing for some time ?
