Dyer Observatory (1000 Oman Dr., 615/373-4897, www.dyer.vanderbilt.edu ), a working space observatory operated by Vanderbilt University , has emerged as a popular venue for music, thanks to two ongoing concert series. Music on the Mountain, with Blair School of Music, and Bluebird on the Mountain, with the the Bluebird Cafe , bring live music to this dramatic and one-of-a-kind spot. Imagine a night of fine music enjoyed under the stars, with the fresh air and the atmosphere of the forest all around you.
Every October the Grand Ole Opry  celebrates its birthday with Opry Month, four weeks of star-studded performances, including several at the Opry’s original home, the Ryman Auditorium . Get your tickets early, since these shows are always popular.
Also taking place on Thursday nights in the summer, Bluegrass Nights at the Ryman is a concert series that features some of the best pickers in the country. Starting in June and ending in July, this Ryman Auditorium  series is always popular.
For a laid-back evening in a one-of-a-kind setting, check out the Tennessee Jazz and Blues Society’s concert series Jazz on the Lawn (www.jazzblues.org ). On Sunday evenings from May to October, jazz and blues artists take the stage on the lawns of some of Nashville’s  most historic homes, including Belle Meade  and Cheekwood . Bring your own picnic and blanket.
