[2][3] The style of Gaelic psalm singing is influenced by piobaireachd music native to the Scottish Highlands, with frequent and distinctive use of ornamentation and grace notes.
Lined out singing was the main form of worship throughout colonial America and the early United States, as English, lowland Scottish, and Ulster-Scots immigrants would all have utilized the style.
Gaelic psalm singing was the main inspiration behind the Runrig song "An Ubhal as Àirde (The Highest Apple)" on their album The Cutter and the Clan.
Gaelic psalm singing has been made widely available through the "Salm" series of albums produced by Lewis native Calum Martin.
Three volumes have been released so far, as well as a live album recorded at Celtic Connections entitled Salm and Soul featuring the Gaelic singing paired with an African-American gospel choir.
