Its main instruments are associated with the Goombay drum, Accordion also known as a Concertina, and a Hand saw. In 1886 an article in the Nassau Guardian mentions the usage of the Banjo, Drums, Concertina and other instruments during a celebration by Black Bahamians. The Concertina is also referenced to be in use in Nassau by Black Bahamians by William Drysdale in his book "In sunny lands: out-door life in Nassau and Cuba pg 29" written in the early 1880's.

Pounds per square inch be added to any pressure reading made in air at sea level. The converse is pounds per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psia) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to something other than ambient atmospheric pressure, then the units would be pounds per square inch differential (psid). The kilopound per square inch (ksi) is a scaled unit derived from psi, equivalent to
