Jim Shubert blows on a pitch pipe Wednesday, Feb. 13, 2013 at the Jenkins' residence in Estero, Fla. The for hire barbershop quartet, The Tropical Depressions, surprises dozens of neapolitans each year by singing love songs to them in public or at their work as a gift from loved ones. They usually sing one to three songs of which "Heart of my Heart" and "Let me Call you Sweetheart," are popular favorites. Shubert arranges the music for the group sometimes in a lower key due to range constraints. B flat is "the concert key" for the group a starting position easy to work off of with several pieces.
