Baroque instruments included some instruments from the earlier periods (e.g., the hurdy-gurdy and recorder) and a number of new instruments (e.g, the cello, contrabass and fortepiano). Some instruments from previous eras fell into disuse, such as the shawm and the wooden cornet. The key Baroque instruments for strings included the violin, viol, viola, viola d'amore, cello, contrabass, lute, theorbo (which often played the basso continuo parts), mandolin, cittern, Baroque guitar, harp and hurdy-gurdy. Woodwinds included the Baroque flute, Baroque oboe, rackett, recorder and the bassoon. Brass instruments included the cornett, natural horn, Baroque trumpet, serpent and the trombone. Keyboard instruments included the clavichord, tangent piano, the fortepiano (an early version of the piano), the harpsichord and the pipe organ. Percussion instruments included the timpani, snare drum, tambourine and the castanets.
