Domenico Alberti (c. 1710 – 14 October 1740) was an Italian singer, harpsichordist, and composer whose works bridge the Baroque and Classical periods.
Alberti was born in Venice and studied music with Antonio Lotti. He wrote operas, songs, and sonatas for keyboard instruments, for which he is best known today. These sonatas frequently employ a particular kind of arpeggiated accompaniment in the left hand that is now known as the Alberti bass. It consists of regular broken chords, with the lowest note sounding first, then the highest, then the middle and then the highest again. This pattern is repeated. Today, Alberti is regarded as a minor composer, and his works are played or recorded only irregularly. The Alberti bass was used by many later composers, and it became an important element in much keyboard music of the Classical music era.
