Terrace sections 10-15 at PNC Music Pavilion are fully reserved. Each of these sections contain seven rows of seating on traditional stadium chairs. Whereas many of the Premier and Pavilion level seats are covered by the roof, the Terrace is fully exposed to the elements.

Ticket prices in these sections tend to be a lot less expensive than other reserved seating, making the Terrace a good cheap-seat alternative to the general admission (and seat-less) Lawn.
