It must be made of weighty American pernambuco or of logwood. The head may not be too low, and must be at least as high again as that of a violoncello bow. The frog is made
From contemporary reports it is clear that Müller´s large and intensive sound was very convincing. None less than Hector Berlioz wrote in his Mémoires about Müller:
"There is a remarkable artist in the Darmstadt orchestra. His name is Müller...

I heard him play a wonderful Adagio, causing a critical audience to become deeply moved."
Müller was involved in the festival for the unveiling of the Mozart monument in Salzburg in September 1842, including in the performance of Mozart´s aria
