"Mucho gusto" is an instrumental piece originally recorded by Percy Faith for the 1961 album Mucho Gusto! More Music of Mexico. The piece is, like the rest of the album, influenced by Mexican music. It has a high, galloping tempo and an advanced arrangement, where the melody is played by alternating strings, brass and percussion. The piece is known for its use of whistles and whips, as well as instruments that are typical of Mexican music, like guitars, maracas and trumpets.
Mucho gusto is Spanish for "very nice (to meet)" or "bon appetit".
Theme music is a piece that is often written specifically for a radio program, television program, video game or movie, and usually played during the intro, during title sequence and/or ending credits. If it is accompanied by lyrics, most often associated with the show, it is a theme song.
The phrase theme song or signature tune may also be used to refer to a song that has become especially associated with a particular performer or dignitary; often used as they make an entrance.
"Bésame Mucho" (Kiss me a lot) is a song written in 1940 by Mexican songwriter Consuelo Velázquez.
It is one of the most famous boleros, and was recognized in 1999 as the most sung and recorded Mexican song in the world.
