A local municipal official named W. Schmölzl introduced him to the guitar, giving him scores and tuition materials from Sor, Giuliani, Legnani, and Mertz.
[1] In 1848, after a number of successful recitals in his hometown, he set out on a tour through Germany together with a certain Loe, one of his most talented pupils.
Apparently, they were not successful and on the brink of returning home when at Darmstadt, their fate turned: "Having to pass through Darmstadt on their journey they were quite unexpectedly commanded to play before the court and they received genuine and hearty applause from the Hereditary Grand Duke and Duchess, the latter being a daughter of King Ludwig of Bavaria.
For some of his publications, he used the pseudonym "A. Caroli", for example for his guitar method Vollständige Guitarreschule and his two collections of short pieces called Esmeralda.
In spite of his international tours and his method being translated into English and French, Bone (1914) wrote "Bayer is held in the highest estimation as a composer by his countrymen, but he is practically unknown out of Germany".
