An Tiompan Gàidhealach
The word 'timpán' was of both masculine and feminine gender in classical Irish. It is theorised to derive from the Latin word 'tympanum' (tambourine or kettle drum) and 'timpán' does appear to be used in certain ancient texts to describe a drum.
The adjective 'timpánach' referred to a performer on the instrument but is also recorded in one instance in the Dánta Grádha as describing a cruit. The feminine noun 'timpánacht' referred to the art or practice of playing the tiompán.
