Soda bread versions are unleavened, but from the early 19th century bannocks have been made using baking powder, or a combination of baking soda and buttermilk or clabbered milk. Before the 19th century, bannocks were cooked on a bannock stone (Scots: stane), a large, flat, rounded piece of sandstone, placed directly onto a fire, then used as a cooking surface. Several varieties of bannock include Selkirk bannocks, beremeal bannocks, Michaelmas bannock, Yetholm bannock, and Yule bannock. The traditional soda farl is used in the full Scottish breakfast along with the potato scone (Scots: "tattie scone"). In Serbian tradition, soda bread is prepared
Irish traditional music The most common instruments used in Irish traditional dance music, whose history goes back several hundred years, are the fiddle, tin whistle, flute and Uilleann pipes. Instruments such as button accordion and concertina made their appearances in Irish traditional music late in the 19th century. The 4-string tenor banjo, first used by Irish musicians in the US in the 1920s, is now fully accepted. The guitar was used as far back as the 1930s first appearing on some of the recordings of Michael Coleman and his contemporaries. The bouzouki only entered the traditional Irish music world in the late 1960s.
