Choro is a musical style from Brazil in which typically a mandolin, clarinet or another lead instrument is backed up by plucked instruments like the guitar and cavaquinho (a small four-stringed guitar), and by percussion instruments such as the pandeiro (similar to a tambourine).
The music is mostly virtuoso and rythmically complex. A master of the genre was the mandolinist Jacob Bittencourt, known as Jacob do Bandolim. His recordings are still listened to today and contemporary groups learn from them.
Some mandolinists who come from classical or bluegrass backgrounds play Brazilian choro
