CONCERTO GROSSO

Concerto grosso is a form of  Baroque music.

The musical material is passed between a small group of soloist-the concertino- and a full orchestra-the ripieno or concerto grosso/big concert.

Listen to the opening of Bach's Bradenburg Corcert No4.

The solo group of violin and two flutes are prominent at the begining and are then joined by the ripieno strings.The harpsichord is playing the continuo.

.

This is in contrast to the solo concerto which features a single solo instrument with the melody line ,
accompanied by the orchestra.
