This evening of music was organized, in part, to highlight the sound of the pardessus de viole, a tiny member of the viola family that was primarily played in 18th century France by upper-class women. It has been rescued from obscurity by players like Tina Chancey, who's visiting Portland on the 16th to lecture a bit about these antique instruments and perform works from the baroque period. The program includes what is being called the first "modern performance" of Antoine Forqueray's lilting and ornate bass viol suites using the pardessus de viol and harpischord. ROBERT HAM
