<P> Colombian music can be divided into four musical zones: the Atlantic coast, the Pacific coast, the Andean region and Los Llanos . The Atlantic music features rhythms such as the cumbia, porros and mapalé . Music from the Pacific coast such features rhythms such as the currulao--which is tinged with Spanish influence--and the Jota chocoana (along with many more afro - drum predominating music forms)--tinged with African and Aboriginal influence . Colombian Andean has been strongly influenced by Spanish rhythms and instruments, and differs noticeably from the indigenous music of Peru or Bolivia . Typical forms include the bambuco, pasillo guabina and torbellino, played with pianos and string instruments such as the tiple guitarra . The music of Los Llanos, música llanera, is usually accompanied by a harp, a cuatro (a type of four - string guitar) and maracas . It has much in common with the music of the Venezuelan Llanos . </P> <P> Apart from these traditional forms, two newer musical styles have conquered large parts of the country: la salsa, which has spread throughout the Pacific coast and the vallenato, which originated in La Guajira and César (on the northern Caribbean coast). The latter is based on European accordion music . Merengue music is heard as well . More recently, musical styles such as reggaeton and bachata have also become popular . </P> <P> Merengue típico and Orchestra merengue have been popular in the Dominican Republic for many decades, and is widely regarded as the national music . Bachata is a more recent arrival, taking influences from the bolero and derived from the country's rural guitar music . Bachata has evolved and risen in popularity over the last 40 years in the Dominican Republic and other areas (such as Puerto Rico) with the help of artists such as Antony Santos, Luis Segura, Luis Vargas, Teodoro Reyes, Yoskar Sarante, Alex Bueno, and Aventura . Bachata, merengue and salsa are now equally popular among Spanish - speaking Caribbean people . When the Spanish conquistadors sailed across the Atlantic they brought with them a type of music known as hesparo, which contributed to the development of Dominican music . A romantic style is also popular in the Dominican Republic from vocalists such as Angela Carrasco, Anthony Rios, Dhario Primero, Maridalia Hernandez and Olga Lara . </P> <P> Traditional Ecuadorian music can be classified as mestizo, Indian and Afro - Ecuadorian music . Mestizo music evolved from the interrelation between Spanish and Indian music . It has rhythms such as pasacalles, pasillos, albazos and sanjuanitos, and is usually played by stringed instruments . There are also regional variations: coastal styles, such as vals (similar to Vals Peruano (Waltz)) and montubio music (from the coastal hill country). </P>
