Teens on summer break may want to learn a new instrument. And guitar may be a popular choice, both because the instrument is prominent in popular music and also because the Sonoma County Library is offering free, bimonthly virtual guitar lessons. Suitable for teens and adults, the Zoom classes will teach advanced and beginner students new techniques and how to better teach themselves. The next classes will be held on July 14 and 28 at 2 p.m. Log on to sjsu.zoom.us/j/95463290909?pwd=WHhzQkNpdG9OaENWOENVNkMyQllnQT09 and enter the password guitar to enter the class.
