so when kalkbrenner heard stamaty play a quadrille with variations of his own composition he approached stamaty and made him a business proposal: stamaty would become his pupil and his répètiteur at the same time. a "répètiteur" was an auxiliary teacher to kalkbrenner who in his later years did little teaching himself. kalkbrenner gave fashionable and very expensive piano courses for selected pupils, while stamaty would prepare students for these courses and do all the preparatory teaching.
