The trikiti (standard Basque, pronounced [trikiti]) trikitixa (dialectal Basque, pronounced [trikitiʃa]), or eskusoinu txiki ("little hand-sound", pronounced [es̺kus̺oɲu tʃiki])) is a two-row Basque diatonic button accordion with right-hand rows keyed a fifth apart and twelve bass buttons. The onomatopoeia trikitixa, apparently stemming from the sound emitted by the tambourine, originally referred to a traditional Basque ensemble, made up of the instrument which now bears the name as well as alboka, txistu and other instruments.
