Leonhard von Call (19 March 1767 – 19 February 1815), sometimes referred to as "Leonhard de Call", was an Austrian composer and virtuoso on the mandolin and guitar. During his lifetime he focused less on performing and more upon teaching and writing music for others to play. A virtuoso, he wrote not for other virtuosos but for the people he was teaching or amateurs, and today it is felt by some musicians that his works "made no great technical demands".[
