Johann Baptist Wanhal (May 12, 1739 – August 20, 1813), also spelled Waṅhal (the spelling the composer himself and at least one of his publishers used), Wanhall, Vanhal and Van Hall (the modern Czech form Jan Křtitel Vaňhal was introduced in the 20th century), was an important Czech classical music composer. He was born in Nechanice, Bohemia, and died in Vienna.
Wanhal was born in Nechanice, Bohemia, into serfdom in a Czech peasant family. He received his first musical training from his family and local musicians, excelling at the violin and organ from an early age. From these humble beginnings he was able to earn a living as a village organist and choirmaster. He was also taught German from an early age, as this was required for someone wishing to make a career in music within the Habsburg empire.
By the age of 21 Wanhal must have been well under way to become a skilled performer and composer, as his patron, the Countess Schaffgotsch, took him to Vienna as part of her personal train in 1760. There he quickly established himself as a teacher of singing, violin and piano to the high nobility, and he was invited to conduct his symphonies for illustrious patrons such as the Erdődy families and Baron Isaac von Riesch of Dresden. During the years 1762-63, he is supposed to have been the student of Karl Ditters von Dittersdorf, even though they were born the same year. Baron Riesch sponsored a trip to Italy in 1769, so that Wanhal could learn the Italian style of composition, which was very much in fashion. To return the favour, Wanhal was supposed to become Riesch's Kapellmeister.
The details of Wanhal's journey to Italy are scant, but it is known that he met his fellow Bohemians Gluck and Florian Gassmann in Venice and Rome respectively. The Italian journeys present the only knowledge we have of Wanhal writing operas: He is supposed either to have written operas over the Metastasian operas Il Trionfo di Clelia and Demofonte, either by himself, or as a cooperation with Gassmann, where Wanhal supplied some or all of the arias; these works have been lost. In additions to his documented travels in northern and central Italy, Wanhal was supposed to travel to Naples – arguably the most important centre of music in Italy at the time – but never seems to have gotten there.
