Cristina Alís Raurich plays several early keyboard instruments of the Middle Ages and the Early Renaissance: portative organ, positive organ, clavicimbalum, hammered clavicimbalum and clavicytherium. Her repertoire consists of music from the High Middle Ages to the 16th century.
She has been collaborating with the organ maker Walter Chinaglia with whom she has developed a new model of portative organ. This instrument, developed through the study of written and iconographic sources, combines elements of late 12th- and 13th- century organ models: The prototype presents a small goldsmith-bellow attached to the instrument, a mostly diatonic keyboard, copper pipes (cuprum purissimum) and a strip that allows for the instrument to be hanged from the body. This is the first reconstruction of an instruments of its kind.
