Castañeda had the opportunity to train in Paris . When he returned home, Guatemala founded the Ars Nova Orchestra , made up of professionals and amateurs. At the request of President Jorge Ubico -who was his cousin- this orchestra was converted into the official state grouping, having to take the name of "Progressive Orchestra" (1936). After the 1944 Revolution , the orchestra was renamed the National Symphony Orchestra (1945), a name that it has preserved to this day.
