[1][2] He travelled to Europe in June 1825, and met musicians including Ignaz Moscheles, Karl Czerny and Ludwig van Beethoven; it is thought that he did not receive lessons from them.
He moved to Montreal in 1837; apparently unsuccessful there as a teacher, he returned to Quebec City by 1841.
[2] In that year Molt was appointed organist at Québec Basilica,[1][2] where he established a cathedral choir; in 1845 he published Traité élémentaire de musique vocale.
He published during this time A New and original method for the pianoforte, 51 progressive lessons, and The pupil’s guide and young teacher’s manual, or the elements of piano forte playing.
La lyre canadienne: répertoire des meilleures chansons et romances du jour, published anonymously in Quebec in 1847, is attributed to Molt.
