National Anthems of countries like Bosina, Herzegovina, Kosovo, San Marino actually have no official lyrics but only musical instrumentals. The Marcha Real, which translates to "Royal March" in English, is the national anthem of Spain. It is one of the few national anthems in the world that is purely instrumental, without any lyrics. The anthem has a long history and is closely associated with the Spanish monarchy. The Marcha Real was originally composed in the late 18th century by an unknown composer, although it is often attributed to Manuel de Espinosa de los Monteros. It was first adopted as the Spanish national anthem in 1770 by King Carlos III, making it one of the oldest national anthems in the world. The Marcha Real has undergone several modifications and adaptations over the years, but its basic melody has remained largely unchanged. It is a lively and majestic march, characterized by its distinctive rhythm and powerful brass instrumentation

Despite its long history and traditional status, the Marcha Real has been a subject of controversy and debate in Spain. Some critics argue that the anthem's lack of lyrics makes it less inclusive and representative of the country's diverse population. Calls for adding lyrics to the anthem have been made over the years, but no changes have been officially implemented. Overall, the Marcha Real remains an important symbol of Spanish identity and heritage, and is played on official occasions such as state ceremonies, sporting events, and military parades. It is a source of national pride for many Spaniards and is recognized as a powerful musical emblem of the country.
