[2] Sein Beda was known for his expertise in the hsaing waing, the Burmese musical ensemble, ranging from traditional instruments such as the saung, mi gyaung, and pattala, to Western instruments like the violin, banjo, mandolin, concertina, and cornet.

[3] He was a favorite musician of Thibaw Min, the Konbaung dynasty's last reigning monarch, and was conferred the title of Nemyo Bala Kyaw Thu (နေမျိုးဗလကျော်သူ) and an appanage of a large village by Thibaw Min for his musical talents.

[4] He became the first Burmese hsaing musician to perform in British India, after being invited to the housewarming of Thibaw Min's residence in Ratnagiri.

[3] During the British colonial period, Sein Beda introduced various innovations to the ensemble, including decorating ensemble stands with traditional Burmese motifs and glass mosaic, introducing a jazz band to the ensemble, creating spotlights, and introducing musician uniforms.

[5] Beda died of a throat problem (possibly cancer) on 8 October 1942 in Rangoon.
