A "Trad Session" is a gathering where musicians come together to play traditional music, often in an informal setting like a pub or community center. These sessions typically feature instruments such as the fiddle, accordion, bodhrán, and tin whistle, and focus on styles from various cultures, particularly Irish and Scottish folk music. Participants usually play by ear, sharing tunes and improvising together. The atmosphere is friendly and welcoming, encouraging both experienced musicians and newcomers to join in. Listeners often enjoy the lively performances, which can include singing and dancing, making it a vibrant cultural experience.
