When I started playing with solo strings I used Corelli because it was the only set of solo strings I had. They had been given to me, I couldn't afford a new set. Corelli strings are very dangerous, they are very thin and give a very bright sound. The player thinks it works well and from the players seat they do sound well. In the concert hall they don't sound at all. The sound is so small that the player simply looks like a very shy person who is afraid of playing. I also had problems with intonation when using these strings, if your tone isn't working the intonation will probably be bad so this is my warning to you. Don't use Corelli solo strings! They might be ok for recording...haven't tryed that.
