Wikipedia: Domenico Alberti

He is known in musical history as the writer of dozens of sonatas in which the melody is supported from beginning to end by an extremely familiar formula of arpeggio accompaniment, consequently known as the Alberti bass. He thus shows how advanced was the decay ofpolyphonic sensibility (as a negative preparation for the advent of the sonata-style) already during the lifetime of Johann Sebastian Bach. His works have no other special qualities, though it is probable that Mozart's first violin sonatas, written at the age of seven, were modelled on Alberti in spite of their superior cleverness.
