The musical style of 21st-century Catholic music varies greatly. Much of it is composed so that choir and assembly can be accompanied by organ, piano, or guitar. More recently, due to style preferences and cost, trends show fewer and fewer parishes use the traditional pipe organ, therefore this music has generally been written for chorus with piano, guitar, and/or percussion accompaniment. Some songs including "One Bread, One Body" (Foley) were arranged, often by others than the composers, for pipe organ. Although initially, the late 20th-century genre was "folk-sounding", it has matured over the last 30 years to a much more eclectic sound of its own.
