The tres (Spanish for three) is a guitar-like three-course chordophone of Cuban origin. The most widespread variety of the instrument is the original Cuban tres with six strings. Its sound has become a defining characteristic of the Cuban son and it is commonly played in a variety of Afro-Cuban genres. In the 1930s the instrument was adapted into the Puerto Rican tres, which has nine strings and a body similar to that of the cuatro.
By most accounts, the tres was first used in several related Afro-Cuban musical genres originating in Eastern Cuba: the nengón, kiribá, changüí, and son. Benjamin Lapidus states: "The tres holds a position of great importance not only in changüí, but in the musical culture of Cuba as a whole." One theory holds that initially, a guitar, tiple or bandola, was used in the son. They were eventually replaced by a new native-born instrument, a fusion of all three, called the tres. Helio Orovio writes that in 1892, Nené Manfugás brought the tres from Baracoa, its place of origin, to Santiago de Cuba. Fernando Ortíz asserts a contrary theory that the tres is not actually a Cuban invention at all, but an instrument that had already existed in precolonial-era Spain. A musician who plays the Cuban tres is called a tresero. There are variants of the instrument in Puerto Rico and the Dominican Republic.
The Cuban tres has three courses (groups) of two strings each for a total of six strings. From the low pitch to the highest, the principal tuning is in one of two variants in C Major, either: G4 G3, C4 C4, E4 E4 (top course in unisons), or more traditionally: G4 G3, C4 C4, E3 E4 (top course in octaves). Note that when the octave tuning is used, the order of the octaves in the first course is the reverse of the order in the third course (low-high versus high-low). Today many treseros tune the whole instrument a step higher (in D major): A4 A3, D4 D4, F#4 F#4 or A4 A3, D4 D4, F#3 F#4.
The Puerto Rican tres is an adaptation of Cuban tres. Investigators agree that the creation of the instrument was probably caused by the 1929 visit of Isaac Oviedo to Puerto Rico during a tour by the Septeto Matancero. Inspired by Oviedo, guitarist Guillero "Piliche" Ayala ordered the construction of a similar instrument for which the body of a cuatro was used. As a result, the Puerto Rican tres is shaped like a Puerto Rican cuatro, with cut-outs, unlike the Cuban variety, which has a guitar-like shape. By 1934 the Puerto Rican cuatro had reached New York and nowadays most Puerto Rican tres players specialize in their national adaptation of the instrument, a notable exception being Nelson González. The Puerto Rican tres has 9 strings in 3 courses and is tuned G4 G3 G4, C4 C4 C4, E4 E3 E4. Players of the Puerto Rican tres are called tresistas.
The typical tres ostinato is the guajeo. It emerged in Cuba in the 19th century in the musical genres nengón, kiribá, changüí, and son. The tres playing technique of changüí, and to a lesser extent nengón, has influenced contemporary son musicians, most notably pianist Lilí Martínez and tresero Pancho Amat, both of whom learned the style from Chito Latamblé.
Benjamin Lapidus presents evidence of the "linear view of the son's development from nengón to kiribá and other regional styles, to changüí, and ultimately to son." The nengón has a limited harmonic range, where the tonic and dominant are accentuated, and the tres is usually placed in the traditional octave tuning (G4 G3, C4 C4, E3 E4). The following nengón guajeo is an embellishment of the rhythmic figure known as tresillo.
Closely related to nengón, the kiribá style emerged in the Baracoa region of eastern Cuba. According to musicologist Olavo Alén Rodríguez, the current thinking in Cuba discards kiribá as a distinct style since research has only found evidence of one song in that style. It was aptly named, "Kiribá".
When playing changüí, the tres is again usually given the traditional octave tuning. The following changüí tres guajeo consists of all offbeats.
According to Kevin Moore "there are two types of pure son tres guajeos: generic and song-specific. Song-specific guajeos are usually based on the song's melody, while the generic type involves simply arpeggiating triads." The rhythmic pattern of the following "generic" guajeo is used in many songs. Note that the first measure consists of all offbeats. The figure can begin in the first measure, or the second measure, depending upon the structure of the song.
Tres solos were first constructed by grouping guajeo variations together, a melodic/rhythmic approach relying on subtle variation and repetition, that maintains a "groove" for dancers. According to Lapidus, tres solos in changüí typically sound "melodic/rhythmic ideas twice before moving on. This technique allows the soloist to set up a series of expectations for the listener, which are alternately satisfied, circumvented, frustrated, or inverted. The practice has its analogue in what Paul Berliner labels 'a community of ideas,' as motives from these sequences are frequently returned to throughout the course of any given solo."
By the mid twentieth century, tres solos began incorporating the rhythmic "vocabulary" of quinto, the lead drum of rumba. The counter-metric emphasis of quinto-based phrases break free from the confines of the guajeo, which is normally "locked" to the clave cycle. Thus, quinto-based solos are capable of creating long cycles of tension—release spanning many measures.
