A steel band consists of many different sets of steel pans. This can be related to any type of band, choir, or orchestra. The Steel Drum orchestra consists of 4 main voices of Steel pans, but there as many as 8 types that can be built. I will explain 6 types here.

Triple Cello - This set is used to support the upper notes of the bass line. It is also sometimes known to play the melody. This set consists of 3 pans per player, with the sides of the drum cut to about 3/4 of the barrel's full length. These are known to have a very mellow tone. Each barrel has 8 to 9 notes.
