Biographie du compositeur:
Alessandro Rolla was an Italian viola and violin virtuoso, composer, conductor and teacher. His son, Antonio Rolla, was also a violin virtuoso and composer.
His fame now rests mainly as "teacher of the great Paganini", yet his role was very important in the development of violin and viola technique. Some of the technical innovations that Paganini later used largely, such as left-hand pizzicato, chromatic ascending and descending scales, the use of very high positions on violin and viola, octave passages, were first introduced by Rolla.
