When Irish emigrants left Ireland for America, many carried with them physical artefacts of their music – musical instruments and precious manuscripts of song, story, and language – along with the songs and tunes in their memories. In America, greater access to literacy and technology enabled them to create additional musical material: contemporary manuscripts, newspaper columns and contributions, and early sound recordings. While sources of Irish vernacular music abound in America, many remain under-explored. This workshop focuses on written and audio archives of Irish language song produced in America, and considers how such sources might document historical musical idiom.
