Canine teeth, bicuspids, and molars all have cusps. Bicuspids typically have two cusps, one on the cheek or buccal side of the tooth, and one on the tongue or lingual side. Although bi is the prefix for two, a bicuspid tooth will sometimes have three cusps, with two on the lingual side.
The mixture of the indigenous, Spanish and African music and sounds have formed very distinctive music styles that are present today. Ecuador is well-known for marimba, a unique form of music that was introduced by the Esmeraldas. It is a direct and virtually unchanged import from the Western Africa region. Marimba is played on a musical instrument of the same name. The instrument features wooden bars tuned to produce a chromatic scale and with resonators, and these bars are played with small mallets. Pasillo, pasacalle and yarabi are also very popular forms of music in Ecuador.

It is a series of wooden bars which vibrate to produce sound when they are hit with a beater.Hanging below the bars are metal tubes of varying lengths, these are called resonators. The metal tubes affect the sound that is produced, amplifying it and making it richer.t is a series of wooden bars which vibrate to produce sound when they are hit with a beater.
