The band had a major hit with "Tangá," initially a descarga (Cuban Jam) in mambo tempo with jazz soloists, spontaneously composed by Bauzá. "Tangá", which was over time arranged with a more formal arrangement. It is generally considered to be the first true
Afro-Cuban jazz tune. The first descarga [Cuban jam session] that made the world take notice is traced to a Machito rehearsal on May 29, 1943, at the Park Palace Ballroom, at 110th Street and 5th Avenue. At this time, Machito was at Fort Dix (New Jersey) in his fourth week of basic training. The day before at
La Conga Club, Mario Bauzá, Machito's trumpeter and music director, heard pianist Luis Varona and bassist Julio Andino play something which would serve as a permanent sign off (end the dance) tune. On this Monday evening, Bauzá leaned over the piano and instructed Varona to play the same piano vamp he did the night before. Varona's left hand began the introduction of Gilberto Valdes' "El Botellero." Bauza then instructed Julio Andino what to play; then the saxes; then the trumpets. The interlocking riffs soon began to take shape into an Afro-Cuban jazzed up melody. Gene Johnson's alto sax then emitted oriental-like jazz phrases. By accident,
Afro-Cuban jazz was invented when Bauzá composed "Tanga" (the Bantú Congolese word for energy) that evening. Thereafter, whenever "Tangá" was played, it sounded different, depending on a soloist's individuality. In August, 1948, when trumpeter Howard McGhee soloed with Machito's orchestra at the Apollo Theatre, his ad-libs to "Tangá" resulted in "Cu-Bop City," a tune which was recorded by Roost Records months later. The jams which took place at the
Royal Roost,
Bop City and
Birdland between 1948 and 1949, when Howard McGhee, tenor saxophonist Brew Moore, Charlie Parker and Dizzy Gillespie sat in with the Machito orchestra, were unrehearsed, uninhibited, unheard of before jam sessions which at the time, master of ceremonies Symphony Sid called
Afro-Cuban jazz. The Machito orchestra's ten to fifteen-minute jams were the first in Latin music to break away from the traditional under-four-minute recordings and live performances. In February, 1949, the Machito orchestra became the first to set a precedent in Latin music when it featured tenor saxophonist Flip Phillips in a five-minute recording of "Tangá." The twelve-inch 78 RPM, part of
The Jazz Scene album, sold for $25—Salazar (1997). The right hand of the "Tangá" piano
guajeo is in the style known as "ponchando," a type of non-arpeggiated guajeo using block chords. The sequence of attack-points is emphasized, rather than a sequence of different pitches. As a form of accompaniment it can be played in a strictly repetitive fashion or as a varied motif akin to jazz comping. The following example is in the style of a 1949 recording by Machito. 2‐3 clave, piano by René Hernández. With "Tangá," Bauzá was the first to explore modal harmony (a concept explored later by
Miles Davis and
Gil Evans) from a jazz arranging perspective. Of note is the sheet of sound effect in the arrangement through the use of multiple layering. Under Bauzá's direction, Machito and his Afro-Cubans were first band to successfully wed jazz big band arranging techniques within an original composition with jazz oriented soloists utilizing an authentic Afro-Cuban-based rhythm section in a successful manner. e.g. Gene Johnson – alto, Brew Moore – tenor, composition in "Tanga" (1943). ==Master of arranging in-clave==
